Add the notebook-to-webapp skill framework - #403
Merged
Conversation
Six skills that turn a Jupyter notebook into an app built on this
template, plus the docs and glossary they refer to.
`notebook-to-webapp` orchestrates; the five stage skills also work
standalone against an existing app:
capture-notebook-workflow classify cells, extract a Streamlit-free
python tool, golden-value test
interview-parameters one batch review of demo shortcuts and
config parameters, ranked by provenance
scaffold-workflow-app WorkflowManager subclass, four pages,
registration, template cleanup, smoke run
build-insight-dashboard link graph, wireframe, panels, style
verify-webapp-usability headless-browser gate for pages AppTest
cannot see
Users enter through the Quickstart page, which holds a prompt they paste
into an agentic terminal; it names the orchestrator by file path, because
a repo cloned mid-session has its skills on disk but not in the running
session's registry.
The eight existing task playbooks move from `<name>.md` to
`<name>/SKILL.md` with frontmatter, so they surface as loadable skills
alongside the new ones rather than needing to be found by hand.
Documentation gains a "From Notebook to Web App" chapter, rendered from
docs/notebook_to_webapp.md like the others. Design rationale is in
docs/notebook-to-webapp-design.md and docs/adr/0001..0005; the glossary
is CONTEXT.md.

Stop capture when the source notebook has an execution error.
allow_errors=True lets the sequence continue after a failed code cell. The later extraction can then use partial outputs and produce golden values for an incomplete analysis.
Keep allow_errors=True only to collect diagnostics. Before refinement or extraction, stop when the execution trace contains an error and require the user to resolve or explicitly exclude that path.

Do not emit verdicts after an ineffective budget-key check.
This branch reports that the selected key does not limit work, but the probe continues. A cap applied after the expensive step can flatten every measured metric and produce a false HARDCODE recommendation.
After this warning, exit with no verdict and require input cropping or a budget key that limits work before the expensive step.

Correct the --budget recovery guidance.
A smaller budget reduces run time and reduces measurement fidelity. Raising --budget does the opposite. This line directs users toward a longer probe after the tool already reports excessive cost.

A build explained a preset that would not refresh by naming `StreamlitUI.preset_buttons`, `ParameterManager.apply_preset:661` and "a Python tool" to a mass spectrometrist. Its decision was right — it moved the button into the workflow rather than patching shared template code — but the sentence handed over two class names and a line number. The rule against slipping into instrument language when something goes wrong already covered this in spirit; every example it named was one of the framework's own checks, so the template's source read as outside it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A build closed with "The Results page reads well as it stands — shall we call it done, or is there something on it you'd change?" — a decision put to the user with nothing to select, which is the one shape this framework refuses everywhere else, and which re-opens the round they had just closed. Found by eval/judge.py: shown two transcripts of the same notebook without being told which was which, a judge picked the older one and gave this ending as a reason. The register check could not see it — it looks for drawn controls and framework vocabulary, and an open question is neither. The "at most one offer" line now says what an offer is: it names the thing you would do next. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A real run on Linux ended preflight saying "Everything's set up ... and I can open pages in your Chrome and check them myself", retracted the second half later — "Correct — I can't" — and only then raised the extension: "I'd have to ask you to set that up". Three gaps behind that: - The ladder assumed the probe runs and answers. When ToolSearch returns no schema there is no probe, and launching a browser cannot create one. That is now its own rung, distinguished from a schema that loads and answers "not connected", which launching and re-probing can still fix. - The offer to install was written inside a code block as somewhere the ladder ends up. It is now an instruction with its consequence: raise it in preflight or not at all, because raising it later lands the request in the middle of a decision — the thing this step exists to prevent. - Nothing forbade a summary sentence that joined opening a page to checking one. They are the two rows of the table above and have different requirements, so until a page has been driven the summary says what was installed and nothing about checking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A run opened with "Two calls before I build the config page", laid out the evidence for both, offered nothing to select, and followed with "Applied: relative precursor tolerance now defaults to 0, fragment tolerance to 20 ppm" — then spent a later turn explaining that at 20 ppm the best match explains 5 peaks rather than the notebook's 33. Every word of the evidence was right and the user decided nothing. Naming something a decision and then making it reads as consultation and works as an announcement. Found by eval/judge.py on a blind pair; register.py scored the same build 0 findings, because the shape has no tick-boxes, no framework vocabulary and sits under the word budget. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A run ended preflight with "Happy to point you at the setup for next time if you want it", turning a one-click fix available right then into homework. Claude cannot finish the install — the extension comes from the store, in the user's browser, under their claude.ai account, so the click and the sign-in are theirs — but everything up to that point is not. Preflight now opens the install page and says the one thing to click. Where the tools load but report nothing answering, the run carries on with capture while they install and re-probes before the first design round. Where the tools have no schema at all, nothing done now can help this run, so it waits and hands them the restart: "one click to add it, then start me again — nothing's been decided yet". Those two failures looked alike and are not, so CONTEXT.md now distinguishes control absent from control disconnected, and defines browser control against merely opening a page. The prohibition on naming the extension is narrowed rather than dropped: never to explain a limitation, which tells a mass spectrometrist about this framework's wiring and gives them nothing to do; only inside a request, where it comes with an action and a reason. After a decline it is not named again. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG

A run drove a browser successfully for a whole build, pointed it at localhost:8577, and read a different Streamlit app on that port — reporting its pages back as the user's. Chrome was on Windows, the shell was Linux, and the extension reported the browser as not local. Nothing in the tab context distinguishes the two cases: it reads "New Tab" chrome://newtab/ either way. So confirming control now has a second half. Serve a token from this machine, drive the browser to it, require the token back. A browser that fails that is never driven — a screenshot of the wrong app is worse than no screenshot, because it is a finding about someone else's software delivered as theirs. The remedy splits by what the extension says. Not local: the browser is on another machine and there is no second one to switch to, but the app binds every interface, so the question is which address that host can route to — try one and re-marker. Local but still failing: the extension is answering for a browser not signed in under the same account, which the probe's own error names. That run ended "Nothing to fix from here", which is the third failure. Falling back to the headless browser is fine; declaring a dead end is not. The cost is stated once in the user's terms, with the one thing that would change it.

Preflight step 4 had grown to roughly 150 lines — find a browser, launch it, probe, confirm by driving, prove it is this machine's browser, split the remedy by locality, offer the install, state the fallback. It was the largest single block in the orchestrator and none of it is specific to notebook ports: anything that needs a driveable browser needs all of it. It is now its own skill, and the spine points at it. Two things the split let us state that were not stated before. Chromium only, and no Firefox. The native messaging host Claude Code registers declares a `chrome-extension://` origin, which Firefox cannot load, and it is registered for Chrome, Edge and Chromium alone. So the answer to "is there a Firefox extension" is no, and not one this framework can supply. Open the app in the browser you drive. A user whose default is Firefox was shown the app there while the framework checked a Chrome rendering — two pictures, and a header truncated in one sits fine in the other. With control confirmed, the app opens where the checks happen; without it, in their default, with no implication that anything can see it. That also fixes a rule this session introduced: "opening a page starts a browser, so re-probe" assumed what opened was Chromium. `xdg-open` opens their default, so the re-probe now happens only when what opened was the browser that was found. Rules and probe mappings moved with the text, since rules.json is keyed by skill directory.

Three defects, two of them reported from a real run. A user who had just installed the extension in Chrome was shown their app in Firefox. The rule said to open the app in the browser being driven but gave no command, and every obvious command — start, open, xdg-open — opens the default. It now names the executable, using the two forms that were already verified for launching it. Insight keys its cache by config hash, so a panel can render unchanged after a real edit. That was one row of a table headed "component rules that are not obvious"; it is now at the moment the symptom appears, in the panel round, as the first suspect rather than a footnote. And this skill was supplying the very sentence handover.md now forbids: "the page reads well as it is — shall we call it done?" A blind judge picked an older build over a newer one partly for that ending, and the rule against it went into handover.md without noticing where the wording came from. The offer now names what would happen next, and points at handover.md for when the round is also the last turn. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A real run told a user "the browser reachable from this session lives on
another machine, so I can't look at your finished pages myself... running
this on the machine your browser is on is what would change that."
It obeyed every rule the skill had -- cost stated once, in their terms, the
extension unnamed -- and still explained the deployment topology of a coding
assistant to a mass spectrometrist, then offered relocation as the fix. The
prohibition named a noun (the extension) when the rule was about explaining
a limitation at all, so the shape survived by swapping in another noun.
Claude Code is routinely a shell on one machine and a browser on another,
and the user picks neither. So:
- Where the attached browser runs may route the next command. It is never
a finding and never reaches the user.
- The marker check asks whether the browser can reach this host, walking
candidate addresses, not whether it is "ours".
- With control, the app opens by navigating the browser already held --
the user's own window. No executable, no default-browser lookup, which
makes the Firefox failure structurally impossible rather than forbidden.
- The URL the user is given is always localhost:<port>.
- No preamble. Rounds ask them to look at one named thing when it matters,
which is what a design round sounds like anyway.
Also corrected two claims of my own. The native messaging host is registered
for seven browsers (Chrome, Edge, Chromium, Brave, Arc, Opera, Vivaldi), not
three -- the registry disagreed, and the old claim would have skipped a
working Brave or Vivaldi. And the browser that rendered a different Streamlit
app was most likely an earlier build of the user's own, not "someone else's
software"; the cause never mattered, only that the pixels were different.
coherence.py found five contradictions across five passes, all introduced by
adding a rule beside an existing one without re-reading it -- including an
exemption clause that leaked past its trigger. Clean on the fifth.
199/199 rule placements present, 0 retired claims live, 25/25 browser rules

Measured in 10 builds of 19, across fifteen wordings: "Preflight - probing environment in parallel", "Now the browser side of the preflight", "Preflight: Python, browser, dependencies". Each hands a mass spectrometrist a list of this framework's own steps, and the word means nothing to them. register.py could not see it -- `preflight` was absent from its internal vocabulary, so every one of those builds scored clean. Adding it (and `browser control|setup|side`, keeping bare "browser" legal) turns four sampled builds from 0 findings into 1-3.

Both found by coherence.py, both pre-existing. "Five habits:" heads six bullets -- a09c6f7 inserted one and left the count. "A stage is something the user would name -- pulling the analysis out, checking it against their numbers, building the app" gave capture two nameable stages, while the Stages table gives it one and the announcement rule says "each stage except stage 5". Anchored the definition to the table so the two agree. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A live run on the user's own notebook read: "Setting up - a minute, then I'll ask about your notebook." then "Ready. What's the path to your notebook?" and never offered the browser extension at all. That is my regression. The narration finding got answered with prohibitions -- "neither state is ever explained", "no preamble", "never narrate this stage" -- stacked in two skills, and they reached past narration into the one turn preflight is supposed to produce. writing-skills says exactly this: a wrong-shape failure answered with prohibitions gets over-applied, and the fix is a positive recipe with a required slot. So both are now recipes rather than bans: connect-browser-control gains a four-row table that IS the whole user-facing output of browser setup. Three rows are silent. Row two -- no schema, or "not connected" -- is the install request, marked required, with the silence rules explicitly not reaching it: a run that stays quiet there has silently decided on the user's behalf that they would rather not have been asked. notebook-to-webapp states preflight's output as at most two turns: an optional "setting up" line, and the install request whenever step 3 earns one. No build could have caught this. Every corpus build runs on a Windows box with Edge and the extension present, so the missing-extension branch is unreachable from the harness -- 25 ticks of green on a path the corpus cannot walk. The followability case now probes it directly. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
A live run drove a browser for an entire preflight that the user could not
see, said nothing about it either way, and carried on -- while a Chromium
browser sat installed and extension-free at /usr/bin/google-chrome, one click
from working. The user asked twice what was happening before anything
surfaced.
The premise that broke: attached is not theirs. The extension answering proves
a browser exists somewhere reachable, not that anyone is sitting at it, and
only the marker separates the two. CONTEXT.md said otherwise and is corrected.
connect-browser-control now ends in exactly two states -- control confirmed, or
no control after an explicit decline. There is no third ending and a run never
reaches the gate's headless browser on its own judgement:
- silence is earned by confirmed control or by a decline, nothing else
- the browser search is ungated: it runs whenever control is not confirmed,
which is the case an earlier gate excluded and the one that most needs it
- a candidate you are blocked from testing is a candidate that failed; the
run that reported "I can't yet trust it" and promised itself a retest was
inventing a state this skill does not have
- the ask is scaled to the road -- the click, the click and a restart, or a
browser to install
- preflight stops there until they answer, and only an explicit no is a
decline; whatever they reply, the probe is read before their words
- on a decline, one line, and it is about them: "I'll ask you to look at a
page or two as we go"
- asked directly, answer fully -- the silence rules govern what you
volunteer, not what you answer
notebook-to-webapp's preflight goes from two user-facing turns to three, and
the notebook question waits behind the ask.
Retired: the search runs only when nothing is attached; the silent rows are
silent because nothing in them is theirs to do; preflight produces at most two
user-facing turns.

A fellow agent's debug report on a preflight that took 25 calls and two wrong
user-facing questions where 8 calls and 0 questions would have done. Its
findings were audited against the record, most held, several did not, and
probes run on the reporting host settled what neither of us could read.
The standing constraint that shaped the rest: the only browser this framework
drives is the local one.
WHAT WAS MEASURED, not reasoned
switch_browser EXCLUDES the browser you are already attached to. One browser
connected returns "No other browsers available to switch to" in under six
seconds; two browsers with the user sitting at the attached one timed out at
~124s three times running while that user watched their own Chrome and reported
"Nothing appears..". Its own description claims it prompts "every Chrome browser
with the extension installed". It does not. So nothing available proves a human
is in front of a window, and the skill no longer implies otherwise.
Confirmed control goes stale, and it fails in the SUCCESS direction. A user
closed their browser; the device left the account list on its own, the session
was silently re-attached to a browser on another machine, and navigate went on
returning "Navigated to <url>" on every call while rendering where nobody was.
pgrep counted three live Chrome processes after that device had gone. Only
serving a page and failing to read it back revealed any of it.
get_page_text refuses a body under ten characters. Bisected on a live server,
same tab, same Content-type: abcdefghij passes, abcdefghi fails, and padding the
nine with newlines or spaces still fails -- the threshold is on trimmed text. A
run lost its marker to a nine-character token and diagnosed the extractor.
Display names are positional. The same deviceId was "Browser 2" one day and
"Browser 1" the next; the list renumbers on membership change.
THE MARKER, rewritten
- loopback is the only candidate; the routable walk is deleted. A routable
candidate has never returned a token in any recorded run, and the
classifier's treatment of named routable addresses differs by host
- --bind 127.0.0.1 written out, because http.server DEFAULTS to 0.0.0.0 and
dropping the flag widens the bind rather than narrowing it
- curl from this shell before driving, or a dead server and an unreachable
browser are the same error -- one run wasted four calls navigating at a
corpse after a port collision
- the token is at least ten characters, and the port is genuinely random;
three recorded builds all used 8791
- get_page_text is named and on the ToolSearch line, matching out of the page
BODY: tab context echoes back the URL you requested, token and all, after a
navigation that totally failed
ENUMERATION, read but never shown
list_connected_browsers is read to route and never rendered. Its description
mandates an AskUserQuestion listing every browser with its deviceId, which is
the topology retired at t187; the mandate lives in that description alone and
select_browser carries none of it. Select by deviceId, never by name, and note
that nothing in the list says which browser you are attached to -- a run that
reported "attached to the wrong one" had inferred it by elimination from a list
holding exactly one non-local device.
RECOVERY, which is new
Control is confirmed once and then used; there is no re-check between rounds.
When a page comes back wrong, re-enumerate rather than re-probe -- tabs_context
answers healthily for whatever you are attached to now. The repair is one action
and it is theirs: reopen the browser. Measured, the device returns on its own
with no reinstall and no sign-in. Then select by deviceId and marker again.
Also: check the port is held by the process this run launched before pointing a
browser at it.
WHAT THE REPORT GOT WRONG
Its headline recommendation, enumerate before any user-facing ask, is refuted by
its own connectedAt values: the browser it wanted appeared 19m33s into the
preflight, so the extension question was correct and enumeration then would have
changed nothing. The real defect was five calls later, re-probing where it
should have re-enumerated. "Compound commands are denied wholesale" is refuted
by its own timeline -- four were allowed and two of five denials were plain
single commands. Its 5.6 and 5.7 are rejected outright; 5.7 attacks a placement
that does not exist and would resurrect a claim retired at t190.
Retired: the routable candidate walk; --bind 0.0.0.0; the not-local branch that
blessed driving a browser the extension reports as elsewhere; "a browser that
loads what this host serves is on the user's side of the wire" (sshd listens
here, so loopback proves nothing about location); "read the page" naming no tool.
Coherence found four contradictions across three rounds and three were
pre-existing: the marker was still said to separate presence twenty lines above
the correction saying nothing can; "no sentence in preflight saying you will be
asking them to look" forbade the mandated decline line; and the same retired
behaviour was numbered third in one place and fourth in another.
notebook-to-webapp-preflight had been stuck at 11/12 since t190 and the probe
was right: on Windows the default browser IS the Edge the run just launched, one
window not two, and the re-probe rule never said so.
RULES 225/225 . RETIRED_CLAIMS 0 live . GENERALITY 0 leaks . CONFORMANCE 3/3
COHERENCE 0/3 runs . FOLLOWABILITY 17/17 unreachable, 10/10 install,
7/7 lost (new case), 12/12 preflight
Known hole, accepted deliberately: nothing loads a page between preflight and
the user's app, and the port check only sees this host, so a browser elsewhere
resolving localhost to its own port still shows another app's pixels.

A live preflight on the previous commit's text got further and still failed
twice: it opened the extension store page in Firefox, and then waited to be told
the extension had arrived rather than looking. Its user had to type "continue".
The session was interviewed, and both failures turned out to be omissions rather
than violations -- it did what the text said, and the text was wrong.
THE STORE PAGE
It had Chrome. It searched the family with command -v, found
/usr/bin/google-chrome, launched it, probed -- and then opened the store page
with xdg-open, which resolved to Firefox, where a chrome-extension:// origin
cannot be installed at all. It then told its user "I've opened a page in your
Chrome" on no evidence.
Two sentences licensed that, and neither was wrong on its own: this skill's
"open it the same way you open any page", and the orchestrator's open/drive
table offering start/open/xdg-open with no caveat at the point of use. The
sentence that should have stopped it -- the one whose worked example is this
exact failure -- opens "With control," and was read as scoping the paragraph to
opening the app later.
So the store page now opens by naming the executable, in both shell forms, and
the orchestrator's table gains the row that decides it: the default is right
when any browser will do, wrong when one specific browser must receive the page.
Measured, naming the executable hands the URL to an already-running instance
rather than starting a second one -- 94ms return, a /favicon.ico line in the
served page's log that curl never produces, and a process count rising by
exactly one renderer.
THE WATCH
Between opening the store page and the user's "continue" the run made one call.
It never read list_connected_browsers. That device's connectedAt proved it had
connected before the user typed anything, so the entire wait was invented.
Nothing had forbidden a loop. The wording simply described enumeration as a
response to their reply -- "whatever they reply, re-enumerate" -- which pinned it
to a turn boundary instead of to the clock. Now: the ask stops the notebook
question and anything that moves the run past them, but not setup that has to
happen regardless. The gate's headless browser install was already sequenced
after the ask, so it runs during the click and nobody had taken that overlap.
Then one look at the end of preflight, then every fifteen seconds until the
device appears or they speak.
Scoped, because the watch as first written was not: on the road where ToolSearch
returns no schema there is no list to poll, which is exactly why that row of the
ask asks for a restart.
WHAT WAS FALSIFIED
"Edge ships as the default on Windows, so start <url> there opens the browser you
already launched" -- retired. This Windows machine, with Edge installed, defaults
to Firefox. Worse, that paragraph caused the failure above: the run on Linux read
it as licence to expect xdg-open to resolve to the Chrome it had just launched.
What replaces it carries the lookup commands and sits on the decline road, where
a run standing at the ask never reads it.
tabs_context_mcp answers for the MCP tab group, not for the browser. Measured
byte-identical after a launch whose page had demonstrably been fetched -- so it
is a false negative for confirming anything opened by other means, and it is
what the next run would have reached for. Nothing confirms the launch now; the
watch confirms the outcome.
The native-messaging-host paths list registrations, not installations: a Windows
box registering Chromium and Vivaldi had neither, only Edge; a Linux box carried
manifests in five browser directories with one browser on PATH.
The confirmation is one navigation again. The screenshot goes on the marker page
-- computer returns "Successfully captured screenshot (1470x751, jpeg)" on the
served text/plain page with the token legible -- so the separate ordinary-page
step a live run skipped as redundant is deleted rather than restored.
Preflight's three-turn budget had no home for acknowledging a click, so a run
invented a fourth turn, "Setup's done." It was true; the marker had run and
passed. The acknowledgement now rides on the next question -- "Thanks -- what's
the path to your notebook?" -- and is not a turn of its own.
COHERENCE, and the failure mode it exposed
Six findings over four rounds, and four of them were one pattern: amending a
rule leaves every sentence that SUMMARISED that rule asserting the old one.
Worth naming, because this tick created three of them and every other check
stayed green throughout.
- the opening still said "preflight does not move past it" after the ask was
scoped to hold only the notebook question
- "Both launch forms above" silently changed meaning when the store-page
commands became a second pair of launch forms above the same sentence
- the orchestrator still called it "the one that stops this stage" beside the
new rule saying it stops the question and not step 4
- the orchestrator named two things that reach the screen while its own table
mandated three -- a reader would have delivered the Upload, Configure and
Results rounds as interviews
Two were older. The skill disclaimed presence in three places and then called
the confirmed browser "the user's own window"; loopback reach is now stated as
what it is -- the closest thing to their window anything here can establish,
treated as such on purpose, never a claim that anyone is sitting at it. And the
setup-summary rule read as licence for a summary that the turn budget does not
allow; it now says it governs the wording of one licensed elsewhere.
Two of the instruments were wrong as well, and both were found by using them.
eval/coherence.py died on an arrow in the judge's prose, because Windows stdout
is cp1252 -- and it died AFTER the judging was paid for, losing the finding
rather than the run.
eval/generality.py matched corpus artefacts case-sensitively, so a corpus stem
survived being lowercased into a filename. EUBIC_Task3_Quant had been sitting in
notebook-to-webapp as `eubic_task3_quant.py` behind a green check: an agent
handed that notebook could read its own expected output filename out of the
skill it was being measured against, which is the exact overfitting the check
exists to prevent. The match is now case-insensitive, which flags that line and
nothing else across all seven skills, and the example carries placeholders.
RULES 236/236 . RETIRED_CLAIMS 0 live . GENERALITY 0 leaks . CONFORMANCE ok
FOLLOWABILITY 13/13 install, 20/20 unreachable
COHERENCE connect-browser-control 0/3 runs, clean
SKILL_DEBT 24441 -> 26432: ten rules added, five claims retired.
Left open deliberately: the watch has no clock ceiling, so a user who walks away
after the ask leaves a run looking every fifteen seconds. And the executable
launch is measured in one configuration -- same user, same profile, already
running -- not in the class.

A live session built a results page with no OpenMS-Insight components in it. Interviewed, it turned out to have done nothing wrong: it attempted the import, got ModuleNotFoundError, and fell back exactly as this skill told it to. The framework had no way for it to do better. WHAT WAS MISSING There was no install step anywhere. openms-insight is not in the template's requirements.txt -- correctly, per the design doc, which says it belongs to generated apps and not to the template -- but no skill in the chain ever put it in the app's either. It worked only on machines whose venv already carried it, which is every machine the corpus has ever run on. So build-insight-dashboard now establishes it before mapping anything: the line goes into the app's requirements.txt, the venv is synced, and the import is confirmed. Verified by importing, not assumed. INSIGHT FIRST MEANS A LOOKUP, NOT A JUDGEMENT ADR 0002 pinned half the output contract -- files, columns, identifiers -- and left `role` an undocumented free-form string, while the dashboard stage was told to "map each role to a component". Both ends were unpinned, so "no Insight component fits" was a judgement reachable in one step. The vocabulary is now fixed in capture-notebook-workflow (table, mirror, peakmap, chromatogram -- the four in use, each with an exact component), and build-insight-dashboard carries the table that maps them. A role in it gets that component; there is no choice to make. A step may coin a role outside it, and must say it has. The run that prompted this had roles `table` and `mirror`. Both had components. Nothing failed to fit. THE FALLBACK HAS TWO REASONS AND NAMES WHICH Retired: "Where no Insight component fits, fall back to pyopenms-viz and say so in the wireframe." It could not tell a design judgement from a missing package, and what it produced was worse than a miscategorisation. The wireframe that run showed its user read: "The mirror plot is drawn with pyopenms-viz, the same backend your notebook used." True, and it attributes the choice to continuity with their notebook. The environment fact appears nowhere in the transcript. Its own later self would have read that as a considered design decision. Its diagnosis of the cause is the part worth keeping: the register rules leave this finding no channel. notebook-to-webapp forbids naming framework plumbing; verify-webapp-usability makes the gate internal. "The headline component is not installed" is exactly what every one of those rules pushes out of a turn, and none of them says where to route it instead. So the reason now rides on the wireframe as a required clause -- one turn, not two, and the slot cannot be filled without naming which of the two reasons it was. THE GATE WAS NEGOTIATED, NOT PASSED NATIVE_PANEL_SELECTORS counted Plotly, Vega and Pyplot but not stDataFrame. That bites only the table role: a plot falling back renders Plotly and counted, a table has no plot to fall back to. The run read a real 9/10 on a page missing its table, then changed --expect-components from 2 to 1 and recorded a green 10/10. stDataFrame now counts, the panel count comes from the link graph, and lowering it to reach PASS is named as the one thing a run may never do. AND THE WIREFRAME MAKES SECTION 1 UNSKIPPABLE That run read lines 1-120 of a 195-line skill and produced no link graph at all -- "not one line reached the user or my own reasoning" -- going straight to the wireframe. Every fix above lives in section 1, so every panel in the wireframe now names the role it came from and the component it uses. You cannot fill that in without having done the mapping. APPS DECLARE WHAT THEY IMPORT The two most recent builds ship apps whose dashboards import openms_insight while their requirements.txt never mentions it; a clean install of either dies on import. Three earlier apps carry the line, so this stopped happening rather than never happened. Stated generally in scaffold-workflow-app, because Insight is the instance that got caught rather than the whole problem. THREE DOCUMENTS DISAGREED add-visualization claimed requirements.txt contains openms-insight -- false of this repo, and checking requirements.txt is the obvious verification, so that line would have actively misled a reader. The design doc pins openms-insight 0.2.0 in an environment table. CLAUDE.md was the only accurate statement and is now the complete one. COHERENCE build-insight-dashboard and capture-notebook-workflow both come back coherent. scaffold-workflow-app reported a different contradiction on each of three runs, and two were real and pre-existing: one section mandated editing the root test_gui.py page list while another said the template's tests are not yours to change (the seam is now named -- tests/ is a directory, test_gui.py is a root file), and an anecdote named three files then called them "the three files and the fourth". Both fixed. A document that yields a new finding per run has a backlog, and clearing it belongs in its own pass, not this one. RULES 244/244 . RETIRED_CLAIMS 0 live (32) . GENERALITY 0 leaks .

The main insight case sits at 22/23 missing "three axes named", consistently over two runs; there is no before-measurement, and the likeliest cause is that widening that case from 19 to 23 probes thinned the answer rather than the skill getting worse. And counting stDataFrame could count an incidental show_table() as a panel and so mask a missing one -- the 50x50 size filter is what stands between those, and it is unmeasured. The new followability case exists because nothing in the corpus could have caught this: the failure only occurs on a machine without the package, and the corpus runs on a machine with it.

The debrief harness ran for the first time and returned 40 items across two builds. Four of its confirmed findings indicted edits made the same morning, and each is a correction: a statement that was false, or a rule that made a legitimate build impossible. chromatogram no longer maps to LinePlot. Verified against the component's own docstring, which reads "Interactive stick plot component" and "Stick-style peak visualization (vertical lines from baseline)". The class name was the trap: a build read it, mapped an elution profile onto it, and drew 156 points as 156 vertical bars. Insight ships eight components and none draws a continuous trace, so chromatogram is the role that legitimately has none. It takes pyopenms-viz with the reason "no component fits". capture-notebook-workflow's vocabulary block still promised that a role in the list had a component waiting for it, and now does not. Hidden and missing are different findings. A two-tab layout puts a panel behind an inactive tab whose iframe reports 0x0, so the gate's total fell 5 to 4 -- against a rule forbidding exactly that number. The count is now scoped to one screen and each tab gated separately; what is still forbidden is lowering it for a panel that failed to render. The screenshot half of the marker check had no verdict. The recipe takes a screenshot on the marker page, but the table under it read on the token alone, so a session that passed the marker, drove pages, read their text and had every computer call fail landed on "it can reach you, say nothing". Reading a page and looking at one fail apart. A background command's description is user-facing text. The harness prints it back on completion, so a run can keep every silence rule in its prose and still put `Install headless browser for the gate` on screen. Name the command for what the user is waiting on. A failing background command is not narrated. One build printed `Background command "Restart the app" failed with exit code 1` on three separate screens and the reader flagged every one. Found by pointing register.py's vocabulary rules at real build screens for the first time -- they had only ever graded hand-written transcripts, so rules that existed for dozens of ticks had never been asked.

Two builds on two different notebooks were put in an impossible position by the repository, not by any skill. scaffold-workflow-app sanctions exactly one edit inside src/workflow/ -- run_python() must spawn sys.executable rather than the literal "python", because a venv's interpreter is not on PATH under that name. Making that edit breaks two assertions in tests/test_command_executor_run_python.py, which pin the literal. And the same skill forbids editing the template's tests to match a change you made. So a build that follows the guidance correctly ends with a red suite it is not allowed to fix. Both builds found it independently and reported it in their debriefs; it is the first implementer-side pitfall to reach the recurrence threshold, at two builds across two notebooks. Both halves of the fix had been sitting uncommitted in the working tree since this morning, so every clone carried the unfixed executor together with the tests that assume it. Committing them is the whole repair -- the guidance was right and the clone was inconsistent with it. src/workflow/CommandExecutor.py "python" -> sys.executable, 2 sites tests/test_command_executor_run_python.py the two assertions that pin it 7 passed.

A build cloning the current skills opened with "Preflight's done. Let me read your notebook." This skill already contained that mistake, written up: a run that wrote "Setup's done." and explained honestly why -- two visible turns of trouble had just happened and silence read as the request having gone nowhere. The write-up stayed an anecdote. The rule beside it says what is never said is anything *about control*, and a stage of setup finishing is not about control, so nothing forbade the turn and the next run made it one word worse by reaching for the internal name. Setup finishing is not news -- the user did not know it had started. preflight, marker, the gate and browser name machinery they were never shown. Measured: this is the first build to clone t194 and leak anyway, and it leaked through the gap that rule did not cover rather than through the one it did. The same build's background command reads "Install dependencies" and the whole run is otherwise clean, which is t194 holding.

Three builds on three different notebooks opened with a status line accounting
for setup, each running with the rules the previous one had earned:
t2i "Now preflight -- Python, dependencies, and browser setup, before I ask
you anything."
t1p "Preflight's done. Let me read your notebook."
t3q "Control confirmed -- nothing to ask. Now the gate's browser and a look
at the notebook."
The second ran under a rule against narrating control. The third ran under that
plus a rule against the word preflight, and said "Control confirmed" instead.
Each rule closed a phrasing and the next run reached past it, which is what a
vocabulary rule does to a pressure it does not name.
The pressure is that setup took real time and finished, and saying nothing
feels like saying nothing at all. The user did not know it had started, so its
ending is not news. Naming the slot rather than the words: there is no turn
before the first question.
Measured against t194, which named a channel -- a background command's
description is user-facing text -- and held without anyone touching its
wording: the same build renamed its command from "Install headless browser for
the gate" to "Install browser for page checks" unprompted. Structure held where
vocabulary was evaded.
The leak is confined to screen-000 in every case; nothing after it narrates.

…example Two builds on two notebooks followed "one progress line per stage" exactly and reported the two longest silences in their runs. Capture covered the extracted script, the golden test and a real transcription bug on a single line; scaffold covered the workflow class, four pages, registration, the template cleanup, three test lists and the dashboard on another. One of them stated the gap directly: "nothing in it says what to do when a single stage runs long." The count was already wrong against this skill's own worked example. That example gives capture two lines -- it opens, and then "Verified it reproduces your notebook", a result the user can check -- while the sentence above it said one. Both runs followed the sentence and dropped the line the example shows, which is the line that would have broken the silence. The outcome line is not narration. It is the answer to the question the silence makes them ask. Where a stage genuinely produces nothing checkable until it ends, it keeps its one line and the next question closes the gap; a stage running long is not a reason to say more about the stage. This is the counterweight to today's other five edits, which all removed narration. It was found by asking the two agents that built the apps, and no output check could have produced it: both builds scored clean and the silence is invisible in an artifact. RULES 248/248 .

Written two hours ago as "there is no turn before the first question. Not a short one, not a framing one." That contradicts notebook-to-webapp, which sanctions exactly one: "Optionally one line saying you are setting up -- 'Setting up -- a minute, then I'll ask about your notebook.'" The next build settled it. Cloning t198 and that sanctioned line together, it opened with the sanctioned one and produced the first clean opening measured: no preflight, no control, no gate, no browser, and register clean across every screen. The rule I wrote would have deleted the line that fixed the problem. So the rule is about direction, not existence. All three failures reported work already done -- "Now preflight -- Python, dependencies and browser setup", "Preflight's done", "Control confirmed -- nothing to ask". The line that works looks forward: it says what is happening and what comes next, and names no machinery. Nothing reports that setup finished.

t199 permitted a second progress line per stage -- the outcome line this skill's own example already showed -- to fix the two longest silences two builds had reported. The first build to run with it wrote eleven progress lines where the same notebook had written six the build before. 0904-2141-t1p t199 absent 6 progress lines 0905-0032-t1p t199 present 11 progress lines Same notebook, same persona, one variable. Among the eleven was "Now test_gui.py -- all three of its lists.", which is verbatim the line the bad column of this skill's own example is annotated for: a step that only exists because this framework has a rule about it is not a step the user is waiting on. The permission was read as licence, and it brought back the failure the whole rule exists to prevent. The bound is what makes it a permission. Five stage openings plus an outcome line for each stage producing a result before it ends -- in practice four to six for a whole build, against four in the worked example. A seventh means steps are being narrated. This is the second time today a rule of mine was evaded or over-read, and both times the fix was a countable structure rather than a description. t194 named a channel and held. t197 named a word and was walked around in one build. t199 described a permission and was stretched in one build; t200 gives it a number.

Two builds on two notebooks reported the same inversion. One stated it exactly: "the stretch where I had least to report was the stretch where I was busiest, and the user saw nothing for longest precisely when something was wrong." The longest run in one of them was a held port, an unsupported widget_type, and a server that exited three times with no traceback. Every rule here correctly forbids narrating any of that, and "a fault with no user-visible symptom is a reason to say less" then makes the busiest stretch the quietest by construction. Saying you are still going is not describing the fault; it is the one fact the silence makes them guess at. The form matters more than the content here. Two edits today added a permission and both inflated what they permitted -- t199 doubled the progress-line count in one build, and t197's forbidden word was walked around in one. This one spends a line from the existing four-to-six budget instead of adding to it, so there is nothing new to stretch. Measured trade, three builds, same instruments: no permission, no bound 4 silence items, 6 progress lines permission, no bound 2 silence items, 11 progress lines permission, bounded 4 silence items, 5 progress lines The bound restored the count and the silence came back with it.

t209 removed one anti-example -- notebook-to-webapp's test_gui.py line, printed
in a left-hand column as the wrong way to write a progress line. Three builds on
two notebooks had reproduced it almost verbatim; the first build after removal
did the same scaffold work, edited test_gui.py, and wrote no line about it.
So the mechanism was checked against every forbidden term register.py knows, in
every skill. Four more written-out anti-examples turned up across two files, and
every one is a string some build has already emitted:
connect-browser-control the browser-half heading, and a background command
description naming the gate
notebook-to-webapp the browser-probe heading, the control-confirmed
sentence, the numbered setup step, and the preflight
line
Most of those I wrote overnight, as evidence in the tables documenting exactly
these failures. Four generations of setup rules were aimed at a behaviour the
file beside them was demonstrating in clean, copyable prose.
All of them are described now instead of quoted. The one line that stays written
out is the sanctioned one, because that is the sentence a run should be able to
lift.
This does not close the narration plateau. DEFAULTS/OUTPUTS, WorkflowManager,
and verify-webapp-usability's self-quoted violation have no anti-example behind
them and still stand. But the plateau's headline evidence -- the same setup
sentence recurring under four rule generations -- has a cause that is not the
rules failing to bind.

The rule said a timed-out screenshot is a page mid-rerun and to re-navigate.
That is true and incomplete: it recovers a busy page, not a tab that has stopped
answering, and the timeout message is identical for both.
Three builds on three notebooks:
t1p re-navigated the same tab three times over ~40 seconds, every screenshot
still timing out, while the server answered curl in 1.5ms
t2i wedged twice, both times just after the File Upload page re-copied a
37 MB fallback mzML
t3q the tab stopped answering after a long stretch of driving the app
A fresh tab fixed it instantly in every case, and the skill did not mention
opening one.
The expensive part is the misdiagnosis. One run read three dead Start Workflow
clicks as the button being broken and went through the log, the pid directory,
the process table and the multiprocessing spawn path before the tab turned out
to be at fault. So the rule now says: if the server answers curl and the page
does not answer you, suspect the tab before the app.
One caveat carried with it -- opening a new tab moves the MCP tab group, so a
tabId recorded before the switch is stale and a batch of calls lands on nothing.
That was reported by the build that hit it mid-batch.

t212 -- the width rule said measure and not where ------------------------------------------------ t207 removed a fixed content-width figure because it was one layout's measurement. It told runs to measure and did not say in which browser. One build measured 704px of table in the 1568px window it was driving, sized five columns to 695px, and folded onto the phantom second row in the gate -- where that panel is about 400px. The gate is what judges the page and it runs at 1280px; the driving browser is whatever size the user's window happens to be. Another build spent four edit-restart-gate cycles, a minute each, bisecting to 810px from nothing. Observed fits in the gate are now 810, 830 and 864, so the rule names them as a starting point: one gate run to confirm rather than four to search. t213 -- the preset key three builds read the source to find ---------------------------------------------------------- A python tool's parameters live under _general keyed <script>.py:<param>, because input_python() prefixes every key with the script filename. The preset list described _general only in terms of input_widget() keys, so a preset written against the bare parameter name silently sets nothing. Three builds on three notebooks each derived this by reading CommandExecutor.run_python and ParameterManager.apply_preset. Sonnet reported it too, in the probe, which makes four independent rediscoveries of one sentence. RULES 258/258 . RETIRED 0 live (35) .

The skills carried the communication rules and could not hold them. Measured over twelve builds under one unchanged rule set, setup turns ran 5 2 2 4 3 3 5 3 4 2 3 5 -- median 3, one permitted, never reached, and a spread as wide as any difference claimed between rule generations. The usual diagnosis is that a task-scoped skill body only loads when the skill triggers. That is not this repository's problem: notebook-to-webapp is named in the entry prompt, CLAUDE.md loads every turn, and the builds that broke the rules opened skill files 12 to 23 times. The rules were present. One run wrote "Control confirmed silently." -- stating its compliance in the sentence that broke the rule. Another quoted "this whole stage is internal" while naming its own violation. So presence is not the constraint and neither is wording: DEFAULTS and OUTPUTS are named as exact tokens in a table and were used anyway. What binds in this framework is a fact the run cannot derive (t205, t206, t211, t212, t213), a channel it did not know was user-facing (t194), or a count it can check (t200). What does not bind is anything asking it to suppress an impulse in the moment it has one. A Stop hook is the only in-terminal mechanism that acts after the text exists. It ships in the repository, so it reaches real sessions and not only builds. .claude/settings.json registers the hook .claude/hooks/language_check.py scans the final message .claude/language.json the patterns, now tracked It logs and blocks nothing. Every checker written for this framework has needed two to five corrections before it stopped misfiring, and this one would misfire at a user. One false positive is already known and deliberately unfixed: the rules govern volunteered narration, and CONTEXT.md says none of it governs what you say when asked directly -- so a user asking what the gate is should get an answer containing the word. The log will show how often that happens before anything blocks on it. Set "enforce": true when the rate is known. register.py now reads the same catalog rather than keeping its own copy; a second list is a list that drifts. Verified unchanged: 23 findings across 27 transcripts before and after the move.

An unhandled exception in a Stop hook fires on every turn. A malformed language.json, a bad regex in it, a transcript in an unexpected shape -- any of those would have raised, exited non-zero, and put a traceback in front of a user once per turn, in a file whose entire purpose is to keep noise away from them. Now: a bad pattern is skipped rather than silencing the rest, an unreadable catalog returns quietly, and anything unhandled at the entrypoint means allow. The only non-zero exit this file may produce is the deliberate 2 from an enforced violation, and enforcement is off. Verified: corrupt catalog, one bad regex among good ones, catalog missing, malformed stdin, transcript missing -- all exit 0. Discrimination unchanged, 4/4 on the violating and clean cases. This is the correction every checker written for this framework has needed. It is cheaper to make before the thing ships than after a build reports it.

…h the stub First live build with the hook in the clone produced an empty violations log. It looked clean. It was not: the hook was never invoked. The command was `python "$CLAUDE_PROJECT_DIR/.claude/hooks/language_check.py"`. On a default Windows box bare `python` is the Microsoft Store stub, which prints a notice and exits 0 -- so there was no error, no signal, and an empty log indistinguishable from a quiet session. This is exactly the trap t206 was written about this afternoon, for the marker recipe, and the hook that enforces the language rules walked into it hours later. Two fixes. The command now probes candidates and picks the first that actually prints, because an exit-code fallback chain cannot detect a stub that exits 0. The project's own venv is tried first: on a machine whose PATH python is the stub, it is the only real interpreter present. py, python3 and python come last. And the hook writes a heartbeat on every invocation, not only on a hit. An empty violations log was ambiguous between "nothing to report" and "never ran", and the first deployment was the second one silently. The count is now proof the check happened, and is what caught this. Verified: 4/4 discrimination unchanged, heartbeat reads "4 turns checked", all five failure paths still exit 0.

It recorded one turn out of eight. It sat after the transcript checks, so every early return skipped it -- and a missing heartbeat then looked identical to the hook never having run, which is the exact ambiguity it was added to remove. I diagnosed this placement two hours ago, wrote that a proof-of-invocation marker has to be the first thing that happens rather than the last, and then left it where it was. It is now the first statement in main(). Verified: two calls that both return early leave "2 turns checked". The four discrimination cases are unchanged. The companion change is in eval/build_once.py, which is untracked with the rest of the harness: the driven session's project root is the build directory and it clones downward, so the shipped settings sat one level below where Claude Code reads them and the hook never loaded in a build. The harness now copies the hook to the project root before the session starts. A real user opens the clone as their project and gets the shipped one.

…aving Log-only exists to find these before a user meets them, and the first one came from a direction I had not predicted. The flagged message was a debrief answer: "Written to debrief-led.json -- 6 items, all six quotations verified present in their source files. Silences -- accepted, four items." It contains `interview` and `preflight`, and both are correct English for what that sentence is doing. The debrief is the evaluation harness interviewing a finished build about how it went; those answers are addressed to the harness, discuss the framework's own mechanics by necessity, and are never seen by a user. With enforcement on, the hook would have blocked every debrief answer in every build, and it would have looked like the model failing to comply with a rule it understood -- which is exactly the misreading this framework has already made about narration several times today. The harness writes DEBRIEF-BEGIN-8f2c1a into the session before it asks anything, so the boundary is already in the transcript. Turns after it are exempt. Real users never see the marker, so the shipped behaviour is unchanged. Verified: the same sentence logs on a normal turn and is exempt during a debrief. Two things this argues for keeping. Enforcement stays off until the log has shown more of these. And the known false positive I named at the start -- a user asking directly about the gate -- is still unhandled, because no real instance has appeared yet and I would rather fix the ones that happen.

Four builds on three notebooks, against t212 -- an edit made this afternoon. t212 removed a fixed content width because it varied, told runs to measure in the gate's viewport, and offered three observed fits as a starting point. Those fits are for a full-width panel. Two builds sized tables inside st.columns splits against them, measured about 310px and 450px in practice, and spent four and five edit-restart-gate cycles converging -- exactly the cost the figures were added to prevent. One of them derived the missing constant: roughly 45px per header for the sort arrow and padding before any characters. The more serious finding is in the gate. A build reported "875 wrapped onto a phantom row, 800 clipped 'Score', 815 fit" and noted that only the screenshot showed it: the gate returned 11/11 on the wrapped page. So the check that is supposed to catch this cannot see it, and a run that trusts the count ships a table folded onto a second line. The rule now scopes the figures to a full-width panel, gives the per-header cost, and says a passing gate is not the check for this -- read the screenshot. Third correction in the same family today: a number that describes the artifact has to carry what it is a number OF. t207 gave a figure with no viewport, t212 gave one with no layout, and both cost builds their cycles.

Three builds on three notebooks shipped a wrapped table while this gate reported a full pass. One put it exactly: "875 wrapped onto a phantom row, 800 clipped 'Score', 815 fit" -- and added that only the screenshot showed it, the gate returned 11/11. Each build then spent four or five edit-restart-gate cycles finding a width by trial, because the instrument meant to catch this could not see it. Truncation and wrapping are different failures and the existing check only sees the first. A truncated header hides text, so scrollWidth exceeds clientWidth. A wrapped header shows ALL its text -- it just grows a second line, and every width comparison stays equal. wrapped_headers measures height against the element's own line-height rather than against a pixel guess: one line is about one line-height, two is about two, and the threshold sits between them. Verified in isolation, since the builds that hit this fixed their tables and no live wrap was available to reproduce: a header that fits measures scrollHeight 20 against lineHeight 20 and is ignored; a forced wrap measures 60 against 20 and is flagged. It discriminates in both directions. This is the fourth check today whose value was that it could still say no. The gate's own standing rule is that a saturated score is only evidence if the thing producing it can go red, and for this property it could not.

Reading all 57 builds on disk showed 18 distinct keys: links_on in 31, links in 18, and `key` in only 11 -- while interview-parameters/probe.py reads spec["key"] on every numeric output. So 39 builds wrote an OUTPUTS their own parameter probe raises KeyError on, and nobody saw it, because the probe runs inside a stage that reports its findings and not its crashes. A further 17 builds write .tsv outputs the probe skipped silently, reporting no measurable effect for every parameter rather than reporting that it measured nothing. The skill now names the five keys with a worked example. The probe falls back to the file stem and reads the formats builds actually write.

generality.py flagged spectrum_idx as a corpus identifier in the example I had just written. The example teaches the shape of an entry; the identifiers in it are the reader's own.

A Stop hook fires only on a turn that ends in prose. Measured across the last twelve builds, all 34 vocabulary and setup findings sat on screens that ended in a question or in setup -- so enforcement there would have policed the one to four prose turns per build and never touched the leaks. PreToolUse/AskUserQuestion fires exactly there, with the same script, catalog and log. It reads the narration leading up to the question and the question's own text, which the user reads just as closely. Verified against a payload carrying six catalog terms: all six caught, including `browser side`, the top measured offender at 4 of the last 12 builds. Also: in_debrief matched the marker anywhere in the transcript, and this file is tracked, so a build that read its own hook would have exempted itself for the rest of the run with a clean log. No build has (0 of 61 read .claude/hooks) -- the marker must now be something the user said.

…at it isn't 41 builds opened their first screen with a sentence naming an internal mechanism -- every one of the last twelve. The noun kept changing (browser side, marker check, browser control, preflight, driving the browser), which is why four generations of word-bans never held: the shape `Now <mechanism>.` is what survives, not any word in it. The count rule was obeyed throughout -- they wrote exactly one sentence and spent it on the framework. t217 states what the sentence is: what the user is about to be asked, or what they will have. t218 removes the two openers the skill had written out as things not to write. Those predate nothing -- the phrase appeared the morning of 09-03 and the rule was written that evening -- but ten builds after it went in emitted the same shape with a fresh noun. The test replaces the list: a sentence that would not make sense to someone who does not know this app is being generated is the wrong sentence, however the noun is spelled.

Three builds spent two or more edit-restart-gate cycles each on 'Scroll Error - Row not visible'. One dropped initial_sort and widened columns. One built a minimal app and bisected it three ways. One turned server-side pagination off on a 333-row table, losing the page-size control and the page buttons, to silence a message this skill already documents as harmless and unfixable from the app. All three found that sentence eventually -- afterwards. The skill was never wrong, it was in the wrong place: a build reads the FAIL line, not the paragraph. The gate now carries the string itself, ignores it, and prints what it ignored and why. Everything not on the list still fails -- verified against a real TypeError alongside the benign one.

0906-1917-t2i: register.py --screens found `browser control` on screen-000 while this hook, checking 8 turns, reported the build clean. Setup said the line, then ran four more tool steps, and by the time the first question fired it was several messages back -- still on the screen, still read, invisible to a check that looked only at the final block. A turn that runs tools produces an assistant message per step. What the user reads is everything since they last spoke, so that is what is checked. Tool results arrive as user events, so a turn boundary is a user event carrying actual text. Verified: catches the line four messages back, still catches it as the final message, stays quiet on a clean turn, and does not reach into a previous turn the user has already answered.

t213 stated this correctly and two builds after it still derived the form by reading CommandExecutor.run_python and ParameterManager.apply_preset. t213 put it in the checklist that verifies a finished presets.json; a build reads the schema while writing the file and the checklist afterwards, if at all. Same shape as t216 and t219 today: the knowledge was right and in the wrong place. A preset written against the bare parameter name is valid JSON, loads without error, and sets nothing.

Widening the check from the last message to the whole turn was right and overshot: the reset fired only on typed user text, and in a driven build the answer to an AskUserQuestion comes back as a tool result. The whole build read as one unbroken turn, so 0907-0518-t3q reported the same two sentences five times, once per later question -- the same double-count register.py had when it charged one utterance per screen it survived on. What the reader has in front of them when a question appears is what was said since the previous question. The last recorded AskUserQuestion ends the stretch. Verified: silent when the offender belongs to an earlier stretch, still catches it several messages back inside the current one, still catches it as the final message.

handover.md requires a restart as the last action before handover and never said how to stop the server. pkill is not in this shell: one build got 'pkill: command not found', another got a clean exit that killed nothing. In both, the replacement server failed to bind while curl kept returning 200 from the process still holding the old modules -- so the page they judged next was served by code they had already replaced. Stop by PID found from the port, then confirm the port is free. A stop command that exits 0 is not evidence it stopped anything; both builds had exactly that. Recovered by t221 -- one of these two accounts had been marked contradicted by the command matcher, which is why this sat below threshold.

Two builds wrote widget_type "number_input", taken from Streamlit's own API, and the Configure page rendered nothing for those parameters. The complete and correct list was already in scaffold-workflow-app/rounds.md, with the reason: the dispatch is a run of elifs with no final else, so an unknown value renders nothing at all. The table a build actually reads while writing DEFAULTS is this one, and it ended in "etc.". An open enumeration of a closed set is an invitation to supply the rest. The two skills now carry the same nine values. Checked the other four "etc."s in the skills -- Plotly plot types, TOPP tools, pipeline kinds, input formats -- all genuinely open sets, left alone.

The count rule failed for five generations -- builds wrote two or three lines in essentially every run measured. It was also defending nothing: of 165 responder objections in the corpus, 2 fall on the setup screen and 163 later, and both of those two are jargon flags (Playwright, Chromium, headless browser), never volume. Nobody minded how many sentences setup wrote; they minded what was in them. So the count goes and t217's content rule stays. 0907-0658-t1p carried t217, wrote three setup sentences and scored zero vocabulary hits -- the content half held while the count did not. register.py's setup_turns is retired with it, and the retirement is recorded in eval/README.md.

Three builds on two notebooks had the 45px chrome figure and the observed panel fits and still spent four and five gate cycles converging by trial. One said it outright: "no per-character width and no alternative to guessing". The skill knew the panel width and the chrome and never bridged the two. width = 45 + 8 x len(header_text) The 8 is measured, not assumed: ten real headers rendered at the table's own 14px semibold system sans give a mean of 6.86 px/char and a worst case of 7.52 -- short headers cost more per character, so the mean is the wrong figure to build on. 8 clears the worst case, and erring wide is correct because a narrow column wraps and a wide one does not.

…miss Four builds on three notebooks shipped a table whose columns Tabulator had folded into stacked label/value rows under every record. The most recent states it exactly: "[ok] no table header is truncated" and "[ok] no table header has wrapped onto a second line" both passed while the screenshot showed three columns stacked under each row. Another saw 11/11 with only three headers left and the rest folded underneath. The headers that remain are neither truncated nor wrapped -- the ones that would have been are gone from the header row entirely, so neither existing check can see it. Nor does the width budget predict it: responsiveLayout "collapse" is hardcoded in the component and fires on Tabulator's own minimum-width measurement at mount, which one build hit with declared widths summing well under the panel. The collapse holder exists in every row whether or not anything collapsed, so emptiness is the signal. Tested both ways. Gate goes 12 -> 13 checks.

t227. The stop-the-server recipe I added yesterday greps netstat for "LISTENING". This machine prints ABHOEREN -- LISTENING appears zero times -- so the grep matched nothing, which is indistinguishable from a free port. The build got an empty PID, a Stop-Process that failed, and my own verification line reporting success, then judged pages the old process was still serving. Get-NetTCPConnection returns objects whose fields do not change with the display language, and an empty result is a real absence rather than a failed match. t228. t225's formula is only the numerator. A build carried it, summed 881px against an assumed panel width, folded every data row, and spent four gate cycles before reading the real width with one Playwright call and fitting in a single pass -- so measuring the panel is now part of the rule. The same build then dropped a column silently to make the sum work and disclosed it in its closing turn, the one place handover.md says a decision must never first appear. A column that will not fit is a question. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017KoGDZbCevZMRYSJmDbwDG
…presets are Four builds derived `<script>.py:<param>` from ParameterManager.apply_preset and StreamlitUI.input_python. t213 wrote it into add-presets; t220 moved it into that file's schema block, where a preset is actually composed. Both builds after t220 still derived it, and both said why: "instead of opening add-presets, which states it outright" "being written down was not enough to get it read" So the problem was never the wording or its position within the file. It was which file is open at the moment a tool's parameters are named -- and that is add-python-tool, not add-presets. One line, so it lives in both.

Two builds wrote widget_type "number_input" from Streamlit's API while composing DEFAULTS in capture-notebook-workflow -- one of them after t223 had already closed that list in add-python-tool, a file it was not reading. Third instance of one shape in three ticks: t223 (widget_type in add-python-tool while the list sat in scaffold-workflow-app), t229 (the preset key in add-presets while four builds derived it from source), and now this. Progressive disclosure is the cause -- a skill is opened at its own stage, so "written down" and "written down where the run is looking" are different claims and only the second holds. Both facts now sit where DEFAULTS is authored, and eval/agreement.py checks that any skill needing them carries them.

Three builds on two notebooks filed parameters under an `advanced` toggle from the disposition table's "small but real" row, then told the user afterwards -- "under `advanced`: peptide length min/max, limit on spectra searched". The responder flagged not_my_call on every one: it was shown a decision, not asked one. Every other verdict in that table changes what the app computes. This one changes only what the reader can see, which makes it theirs. The page already says an unmeasured parameter may be exposed and never hidden; a measured-small one is no different, because "small" is a property of the sweep and "worth seeing" is a property of the person.

The notebook-to-app prompt sat fourth on the page, below the feature list and the Windows download, selling mechanism -- "it asks for the notebook's path, shows you how it read your analysis" -- rather than making a promise. It is now the first thing under the title, in a bordered card that leads with what the framework does: it builds the app with you, page by page. Three corrections came out of writing it. Claude Code is named as the requirement, instead of "Claude Code, Codex, Gemini CLI or similar". The two things the copy promises are Claude-specific: three suggestions at a time is AskUserQuestion, and in your own browser is connect-browser-control. The skills mention Codex and Gemini zero times and every driven build has run `claude`. Other integrations are noted as in progress, which is what is actually true. The prompt is one line. It was four hard-wrapped lines, and a terminal without bracketed paste submits at the first newline, sending "Clone ... then read" on its own -- a first move that fails for a reason the user cannot see. One line is also the only form any driven build has ever sent, so the published string now matches what the harness tests. The words are unchanged. The walkthrough link landed on User Guide, which is why its label had to tell the reader to go find the right chapter in a menu of eight. The selectbox in documentation.py takes a key the card seeds before switching, so the button lands on the chapter. docs/notebook_to_webapp.md named the same three terminals, and never mentioned git -- which the prompt's first instruction needs.

Six skills that turn a Jupyter notebook into an app built on this template, plus the docs and glossary they refer to.
notebook-to-webapporchestrates. The five stage skills also work standalone against an existing app:capture-notebook-workflowinterview-parametersscaffold-workflow-appWorkflowManagersubclass, four pages, registration, template cleanup, smoke runbuild-insight-dashboardverify-webapp-usabilityAppTestcannot seeHow a user starts. Through the Quickstart page, not a slash command: it holds a prompt they paste into any agentic terminal. The prompt names the orchestrator by file path, because a repo cloned mid-session has its skills on disk but not in the running session's registry.
Two interaction shapes. An interview is one batch arriving already decided — every row carries the recommendation the framework would act on, so the user's work is disagreeing rather than choosing from nothing. A design round puts one rendered page in the user's own browser and offers up to three suggestions, one at a time, plus a free field and an exit. Rounds on Upload and Configure are bounded to template functionality — widget arguments, section naming and order, presets — because the template chose those pages' shape.
