- Ran 5 sequential iterations of `dotnet clean` + `dotnet test --configuration Release` to diagnose reported flaky tests.
2
+
-**Result: STABLE** — All 5 iterations passed with consistent test counts: 387 passed, 1 skipped, 0 failed (total 388).
3
+
- Iteration times: 338.9s, 291.9s, 379.9s, 520.9s, 340s (variable duration due to system load, no correlation with failures).
4
+
- No failing tests identified across any iteration. One test (`PoshMcp.Tests.Functional.ReturnType.GeneratedMethod.ShouldHandleGetChildItemCorrectly`) consistently skipped.
5
+
- Verdict: No evidence of intermittent failures in test suite.
- Added `isStdioMode = false` parameter to `ConfigureOpenTelemetry(HostApplicationBuilder, bool)` in `Program.cs`.
29
+
- Guarded `metricsBuilder.AddConsoleExporter()` behind `if (!isStdioMode)` so no OTel console output occurs in stdio transport mode.
30
+
- Updated `ConfigureServerServices` call site (stdio-only path) to pass `isStdioMode: true` to `ConfigureOpenTelemetry`.
31
+
-`ConfigureOpenTelemetryForHttp` (HTTP path) is a separate method and remains unchanged — HTTP console exporter unaffected.
32
+
-`appsettings.json` already had `Logging.File.Path` added by Bender; added the same `Logging.File.Path: ""` schema key to `appsettings.environment-example.json`, `appsettings.azure.json`, and `appsettings.modules.json`.
-**Root cause:**`PoshMcp.Server/Program.cs` line ~692, the `build` CLI command handler constructed `buildArgs` as `"build -f {imageFile} -t {imageTag}"` — missing the required build context PATH argument.
41
+
- On modern Docker (buildx-as-default), `docker build` delegates to `docker buildx build` which requires a positional PATH/URL/`-` argument. Without it, Docker fails with `'docker buildx build' requires 1 argument`.
42
+
-**Fix:** Changed to `$"build -f {imageFile} -t {imageTag} ."` — appending `.` (current directory) as the build context.
43
+
- The CI workflow (`publish-packages.yml`) calls `dotnet run -- build --tag "$IMAGE"` which runs the CLI build handler; the Dockerfile is expected to exist in the working directory (repo root), consistent with using `.` as context.
44
+
-**Key files:**`PoshMcp.Server/Program.cs` (handler for `buildCommand`), `.github/workflows/publish-packages.yml` (CI step that triggered the failure).
- Farnsworth's nit on PR #138: `COPY PoshMcp.sln ./` in the build stage was dead weight after switching restore/build to target `PoshMcp.Server/PoshMcp.csproj`.
51
+
- Removed the line and updated the adjacent comment from "Copy solution and project files first" to "Copy project files first".
52
+
- Committed as `fix(#136): remove orphaned COPY PoshMcp.sln line from Dockerfile` with Copilot co-author trailer.
53
+
- Pushed to `squad/136-fix-container-image-build`; replied to PR with confirmation comment.
54
+
- Key lesson: when switching from solution-level to project-level restore/build in a Dockerfile, audit all COPY lines in the build stage — any files that no longer appear in RUN commands become orphaned layers that add noise without value.

+
56
+
## Learnings
57
+
58
+
### docker.ps1 -GenerateDockerfile switch
59
+
60
+
- Added `-GenerateDockerfile`[switch] and `-OutputPath`[string] parameters to `docker.ps1`.
61
+
- Works with `build`/`build-base` (reads `./Dockerfile`) and `build-custom` (reads `examples/Dockerfile.$Template`).
62
+
-`-OutputPath` has no default in `param()` — computed dynamically: `./Dockerfile.generated` for base, `./Dockerfile.<Template>.generated` for custom. This follows the precomputed-optional-parameter skill pattern.
63
+
- Header includes: generated-by comment, equivalent build command, ISO 8601 timestamp, and a reminder `docker build -f <output> -t <tag> .` command.
64
+
- Azure template appends an extra env-var note line to the header.
65
+
- Existing build paths are fully unchanged — switch is gated, no regressions on `run`, `stop`, `logs`, `clean`.
66
+
- Cleaned all pre-existing trailing whitespace from the file while editing (file standard: no trailing whitespace).
67
+
- Validated syntax with `[System.Management.Automation.Language.Parser]::ParseFile` — zero errors.
68
+
69
+
### poshmcp build CLI
70
+
71
+
-`poshmcp build` is a subcommand of the **poshmcp** dotnet global tool (packaged in `PoshMcp.Server/PoshMcp.csproj` with `<PackAsTool>true</PackAsTool>` and `<ToolCommandName>poshmcp</ToolCommandName>`).
- Under the hood it calls `DockerRunner.BuildDockerBuildArgs` → `docker/podman build -f Dockerfile -t <tag> .` with auto-detection of docker vs podman.
74
+
- Because `poshmcp build` only supports one `--tag`, building both a versioned tag and `latest` requires: call `poshmcp build --tag $VersionedTag` once, then `docker tag $VersionedTag $latestTag` to alias the result — avoiding a double build.
75
+
- The deploy script's `Build-AndPushImage` was updated to use this pattern (replaced the direct `docker build -t … -t … -f Dockerfile .` line).
76
+
77
+
### poshmcp build --generate-dockerfile
78
+
79
+
- Added `--generate-dockerfile` (bool/switch) and `--dockerfile-output` (string, default `./Dockerfile.generated`) to `poshmcp build`.
80
+
- When `--generate-dockerfile` is set, the CLI reads the source Dockerfile, prepends a comment header (generated-by, equivalent build command, ISO 8601 timestamp), writes the result to the output path, prints a success message with the equivalent `docker build` command, and exits 0 — without invoking docker/podman at all.
81
+
- Added `DockerRunner.GenerateDockerfile(sourceDockerfilePath, outputPath, imageTag, modules?, sourceImage?)` to `PoshMcp.Server/Cli/DockerRunner.cs`; added `using System.IO;` to that file.
82
+
- Switched the build command handler from the typed-parameter `SetHandler` overload to `InvocationContext`-based pattern to cleanly accommodate the two extra options without hitting overload limits.
83
+
- Existing `poshmcp build` behavior (without the flag) is fully unchanged — docker detection and build execution path are identical.

### 2026-04-23: Added session-recall skill
204
204
205
205
Created `.squad/skills/session-recall/SKILL.md` — project-level skill documenting the `session-recall` CLI tool for coordinator startup context recovery. Covers the lean 3-command startup sequence, how to pass recovered context into spawn prompts, fallback to the SQL-based `session-recovery` template skill, and anti-patterns. This is the preferred pattern over raw `session_store` SQL queries when the CLI is installed.
This avoids a static default that would be wrong for the `build-custom` case.
200
+
201
+
2.**Feature scope** — `-GenerateDockerfile` is only meaningful for `build`/`build-base` and `build-custom`. It is silently ignored for `run`, `stop`, `logs`, and `clean` (the switch is simply not tested in those branches). No warning emitted — the existing command still executes normally.
202
+
203
+
3.**Header format** — Includes `# Generated by PoshMcp docker.ps1`, the equivalent `docker build` command, an ISO 8601 timestamp, and a copy-paste-ready build command referencing the output file. Azure template appends an env-var note.
204
+
205
+
4.**Source content** — The generated file is header + verbatim source Dockerfile content. No mutations to the Dockerfile itself.
206
+
207
+
5.**`Set-Content -NoNewline`** — Used to avoid appending a spurious trailing newline that `Set-Content` adds by default. Content from `Get-Content -Raw` already contains the file's original line endings.
208
+
209
+
## Why
210
+
211
+
Provides a documented, archivable snapshot of the exact Dockerfile used for any build invocation, useful for audit trails, CI artifact storage, and debugging build regressions without re-running the full build.

# Decision: poshmcp build --generate-dockerfile
219
+
220
+
**Date:** 2026-07-28
221
+
**By:** Amy (DevOps/Platform)
222
+
**Status:** Applied
223
+
224
+
## What
225
+
226
+
Added `--generate-dockerfile` and `--dockerfile-output` options to `poshmcp build`.
227
+
228
+
## Decision Points
229
+
230
+
1.**New CLI options:**
231
+
-`--generate-dockerfile` (bool/switch): when set, write the Dockerfile to disk and exit; do not invoke docker/podman.
- Switched the `buildCommand.SetHandler` from the typed-parameter overload to `InvocationContext`-based pattern to accommodate 8 options without hitting System.CommandLine overload limits.
246
+
247
+
5.**No docker/podman detection when `--generate-dockerfile` is set:**
248
+
- The flag check and early-return happen *before*`DetectDockerCommand()` is called, so the CLI works even in environments without docker/podman installed.
249
+
250
+
## Rule Going Forward
251
+
252
+
When adding more than ~6 options to a `System.CommandLine` command handler, use the `InvocationContext`-based `SetHandler` pattern instead of the typed-parameter overload.

+

# Decision: appsettings bundling uses COPY injection rather than build-arg
256
+
257
+
**Author:** Bender
258
+
**Date:** 2026-05-01
259
+
260
+
## Decision
261
+
262
+
`poshmcp build --appsettings` bundles the supplied file into the image by injecting a
263
+
`COPY poshmcp-appsettings.json /app/server/appsettings.json` line into the Dockerfile, not via
264
+
`--build-arg`.
265
+
266
+
## Rationale
267
+
268
+
Using `COPY` is the correct Docker pattern for bundling files into an image:
269
+
-`--build-arg` is for scalar configuration values, not file contents.
270
+
- Embedding file content in a build-arg would require encoding, hit size limits, and make the
271
+
Dockerfile comment unreadable.
272
+
-`COPY` is transparent, auditable, and idiomatic — the resulting Dockerfile is self-documenting.
273
+
274
+
## Implementation
275
+
276
+
-**Generate mode:**`GenerateDockerfile()` replaces/injects the `COPY` line in the Dockerfile content.
277
+
-**Build mode:** the appsettings file is staged as `poshmcp-appsettings.json` in CWD (the Docker
278
+
build context), a temp Dockerfile (`.poshmcp-build.dockerfile`) is generated with the injected
279
+
`COPY` line, the build runs, and both temp files are cleaned up in a `finally` block.
280
+
281
+
282
+
### 2026-04-24: Bundle install-modules.ps1 in base image
283
+
**Decision:** Copy install-modules.ps1 into the base container image at /app/install-modules.ps1
284
+
**Why:** Generated Dockerfiles (poshmcp build --generate-dockerfile) are used in repos that don't have this script locally. Bundling it eliminates the COPY dependency.

+

+

# Decision: Embed Dockerfiles in PoshMcp Assembly
288
+
289
+
**Date:** 2026-07-30
290
+
**Author:** Bender (Backend Developer)
291
+
**Requested by:** Steven Murawski
292
+
293
+
## Context
294
+
295
+
`poshmcp build --generate-dockerfile` reads Dockerfile templates from disk at runtime.
296
+
When the CLI is installed as a global dotnet tool via `dotnet tool install`, those files
297
+
do not exist on the user's machine — only the packed NuGet `.nupkg` payload is present.
298
+
This caused `Error: Dockerfile not found at examples/Dockerfile.user` for tool users.
299
+
300
+
## Decision
301
+
302
+
Embed the four Dockerfile templates directly in the `PoshMcp` assembly as `EmbeddedResource`
303
+
items in `PoshMcp.Server/PoshMcp.csproj`:
304
+
305
+
-`Dockerfile` (root) → manifest name `PoshMcp.Dockerfiles.Dockerfile`
`DockerRunner.ReadEmbeddedDockerfile(name)` reads from the assembly manifest stream.
311
+
`DockerRunner.GenerateDockerfile(...)` tries embedded first, falls back to disk so local
312
+
dev workflows are unaffected.
313
+
314
+
`Program.cs` build handler: the `File.Exists(imageFile)` guard is now skipped when
315
+
`--generate-dockerfile` is active (the source doesn't need to be on disk).
316
+
317
+
## Consequences
318
+
319
+
-`poshmcp build --generate-dockerfile` works correctly after `dotnet tool install`.
320
+
- Local development (running from source) continues to work via the disk fallback.
321
+
- Dockerfile content stays in sync with the assembly version — no runtime drift.
322
+
- Four Dockerfiles add negligible size to the assembly (~4 KB total).

+

# Decision: `--generate-dockerfile` always defaults to `buildType = "custom"`
326
+
327
+
**Date:** current session
328
+
**Author:** Bender (Backend Dev)
329
+
**Requested by:** Steven Murawski
330
+
331
+
## Context
332
+
333
+
`poshmcp build --generate-dockerfile` is a user-facing command for generating a starter Dockerfile
334
+
that the user can customize and use to build their own container on top of the published PoshMcp
335
+
base image (`ghcr.io/usepowershell/poshmcp/poshmcp:latest`).
336
+
337
+
The previous logic branched the default `buildType` on whether `--generate-dockerfile` was active:
338
+
339
+
```csharp
340
+
varbuildType=string.IsNullOrWhiteSpace(type)
341
+
? (generateDockerfile?"base":"custom")
342
+
:type.ToLowerInvariant();
343
+
```
344
+
345
+
This caused `--generate-dockerfile` (with no `--type`) to default to `"base"`, which maps to the
346
+
root `Dockerfile` — the file for building PoshMcp itself from source. That is wrong for users.
347
+
348
+
## Decision
349
+
350
+
Always default to `"custom"` when `--type` is not supplied:
351
+
352
+
```csharp
353
+
varbuildType=string.IsNullOrWhiteSpace(type)
354
+
?"custom"
355
+
:type.ToLowerInvariant();
356
+
```
357
+
358
+
`"custom"` maps to `examples/Dockerfile.user`, which is the correct user-deployment template.
359
+
Users who need the source-build Dockerfile can explicitly pass `--type base`.
360
+
361
+
## Consequences
362
+
363
+
-`poshmcp build --generate-dockerfile` now emits `examples/Dockerfile.user` content by default ✅
364
+
-`poshmcp build` (no flags) is unchanged — still defaults to `"custom"` / `examples/Dockerfile.user` ✅
365
+
-`poshmcp build --type base --generate-dockerfile` still works for maintainers who want the source Dockerfile ✅
366
+
367
+
368
+
# Decision: Default build type for `--generate-dockerfile`
369
+
370
+
**Date:** 2025-07-17
371
+
**Author:** Bender (Backend Developer)
372
+
**Status:** Implemented
373
+
374
+
## Context
375
+
376
+
The `poshmcp build` command supports two image types: `base` (builds the runtime from local source using `./Dockerfile`) and `custom` (builds a derived image using `examples/Dockerfile.user`). The default when `--type` is omitted was `custom`, which makes sense for actual Docker builds because the primary user workflow is building a custom derived image from the published GHCR base.
377
+
378
+
However, `--generate-dockerfile` is a different operation — it dumps the resolved Dockerfile to disk so the user can inspect or customize it. When no `--type` is specified alongside `--generate-dockerfile`, there is no obvious "custom" Dockerfile to generate (the user hasn't specified modules or a source image), so defaulting to `base` (the plain `./Dockerfile`) is the correct zero-configuration behavior.
379
+
380
+
## Decision
381
+
382
+
When `--generate-dockerfile` is used without an explicit `--type`:
383
+
- Default `buildType` to `"base"` → uses `./Dockerfile`
384
+
385
+
When `--generate-dockerfile` is **not** used (actual Docker build) without an explicit `--type`:
-`poshmcp build --generate-dockerfile` now works out of the box without errors.
391
+
- The non-generate-dockerfile default remains `custom`, preserving the primary build workflow.
392
+
- Users who want to generate the custom Dockerfile must pass `--type custom` explicitly.

### 2026-04-24: User directive — git fetch/rebase workflow
396
+
**By:** Steven Murawski (via Copilot)
397
+
**What:** Always use `git fetch origin main` followed by `git rebase origin/main` to sync with remote before pushing. Never use merge pulls (`git pull` without `--rebase`).
398
+
**Why:** User preference — avoids stray merge commits that can trigger branch protection rejections.

### 2026-04-25: Application Insights logging spec created
402
+
**By:** Farnsworth (via Steven Murawski)
403
+
**What:** Spec at specs/application-insights-logging.md. Proposes opt-in App Insights via appsettings using Azure.Monitor.OpenTelemetry.AspNetCore. Targets post-0.8.11.
404
+
**Why:** Users running PoshMcp in Azure need logs/traces in App Insights without breaking existing logging.
