Code Review
This is an impressive and substantial refactoring that introduces a robust, protocol-driven architecture for agent-to-agent communication, payments, and context management. The switch from Puppeteer to Playwright, along with the addition of a new Terminal User Interface (TUI) and comprehensive documentation, significantly enhances the project's quality and capabilities. The new structure is well-organized and follows modern best practices. My feedback includes a few suggestions to improve the robustness of ID generation, strengthen schema definitions, and enhance the reliability of the new browser automation scripts.

There was a problem hiding this comment.
Generating a taskId using Date.now() and Math.random() is not guaranteed to be unique, especially in a distributed system or under high concurrency. This could lead to task ID collisions. It is highly recommended to use a more robust method for generating unique IDs, such as crypto.randomUUID() which is available in Node.js.

There was a problem hiding this comment.
Using selectors based on text content or generic attributes like [contenteditable="true"] makes the automation script brittle, as they are likely to change with UI updates. If possible, it's much more robust to use stable, test-specific attributes like data-testid. If you don't have control over the target application to add them, consider adding a comment here to flag these selectors as fragile and potential points of failure.

There was a problem hiding this comment.
The protocol for this localhost endpoint is set to https, which will likely cause connection errors in a local development environment. For consistency and correctness, this should be http to match the implementation in packages/core/protocols/a2a/agent-card.ts and avoid confusion for users trying to run the examples.

There was a problem hiding this comment.
The variables userAccount and serviceAccount are used here without being defined in the code snippet. This makes the example incomplete and confusing for anyone trying to run it. Consider defining them inline to make the example self-contained and runnable.

| { mandateId: mandate.id, amount: { value: negotiation.terms!.cost, currency: 'USD' } }, | |

| outputSchema: { | ||
| type: 'object', | ||
| properties: { | ||
| result: { type: 'any' }, |
There was a problem hiding this comment.
The outputSchema for the orchestrate capability uses { type: 'any' } for the result. This weakens the schema contract and provides no information about the expected output structure. It's better to define a more specific schema, even if it's a union of possible result types. If any is truly necessary, a comment explaining why would improve clarity.

| ); | ||
| } |
There was a problem hiding this comment.
Throwing a generic Error for a missing API key makes it difficult for calling code to handle this specific error case gracefully. Consider defining and throwing a custom error class, like ApiKeyMissingError extends Error, to allow for more specific catch blocks (e.g., catch (e if e instanceof ApiKeyMissingError)).

There was a problem hiding this comment.
The authentication flow persists session cookies with await this.saveAuthState('./.auth/aistudio-auth.json'), but the code never creates the ./.auth directory before writing. browserContext.storageState({ path }) fails with ENOENT if the parent directory does not exist, so a first‑time login will throw before the state is written and the user stays unauthenticated. Consider creating the directory (e.g. fs.mkdir(path.dirname(file), { recursive: true })) before calling saveAuthState. Similar calls exist for Labs Flow and Labs Whisk.

The selector uses multiple fallback options combined with commas, which will match any of the elements. If multiple elements match (e.g., both a 'New' and 'Create' button exist), Playwright will click the first one found, which may not be the intended target. Consider using more specific selectors or adding context to ensure the correct element is clicked.

| await this.page!.click(`text="${step.action}"`); |
There was a problem hiding this comment.
Using text=\"${step.action}\" selector is fragile and will break if step.action contains special characters or doesn't exactly match visible text. Consider using more robust selectors like role or data-testid attributes, or add proper escaping for the text selector.

There was a problem hiding this comment.
Filling a contenteditable element with fill() may not work reliably as contenteditable elements aren't standard form inputs. Consider using page.locator().type() or page.evaluate() to set the content for contenteditable elements.

The hardcoded Chrome 120 user agent string will become outdated. Consider using Playwright's default user agent or making it configurable. Outdated user agents may trigger bot detection on some services.

The fetch error handling at line 131 catches all errors and logs error.message, but fetch errors (like network failures) may not have a descriptive message property. Consider providing more context in the error message, such as the endpoint URL and request details.

This makes it easy to build circuits with out‑of‑range qubit references, which will only fail later in the pipeline.A lightweight guard (even just in one shared helper) would make the builder safer to use:
private assertQubitIndex(qubit: number) { if (qubit < 0 || qubit >= this.circuit.qubits) { throw new RangeError(`Qubit index ${qubit} out of range (0..${this.circuit.qubits - 1})`); } }and call it from the gate methods (including both
controlandtargetforcnot).
100-135: Guard preset circuits against insufficient qubits
bellStateandghzStateassume at least 2 qubits, andghzState/qftcan be passed anumQubitslarger thanthis.circuit.qubits, leading to gates on non‑existent qubits.It would be safer to:
- Assert minimum qubits for
bellState(≥ 2) andghzState(≥ 2).- Validate that the
numQubitsargument is ≤this.circuit.qubits, or clamp to the configured value.
This keeps the presets self‑consistent even when the builder is constructed manually.
151-153: Route logging through a logger or debug flag instead ofconsole.log
build()logs directly viaconsole.log, which conflicts with theno-consolerule and can be noisy in production.If you want to keep this instrumentation, consider:
- Injecting a logger, or
- Using a debug flag/env‑controlled logger wrapper instead of
console.log.Alternatively, you can drop the log entirely if it’s only used during development.
packages/services/quantum/index.ts (4)
39-52: Optional: takecircuit.measurementsinto accountRight now the simulation implicitly measures all qubits (
2 ** circuit.qubitsoutcomes) and ignorescircuit.measurements. If you expect downstream tooling to model partial measurement, you may want to:
- Restrict the outcome bitstrings to the measured qubits, or
- Document clearly that the stub always returns full‑register results.
This can be deferred, but it’s good to align expectations early.
69-92:optimizestub is fine, but consider wiring in constraints and determinism togglesThe
optimizemethod is clearly a placeholder, which is fine. Two forward‑looking tweaks that could help:
- At least surface
problem.constraintssomewhere in the returnedsolutionfor easier debugging.- Optionally allow a seed or deterministic mode for tests instead of pure
Math.random().Not urgent, but it will make it easier to evolve this into a real optimizer later.
97-121: TypegetAvailableBackendswithQuantumBackendnamesThe objects returned by
getAvailableBackendscurrently usename: string. Since you already haveQuantumBackend, you could tighten this to:getAvailableBackends(): Array<{ name: QuantumCircuit['backend']; available: boolean; description: string }> {or directly
name: QuantumBackend. That keeps backend identifiers consistent across the module and prevents typos.
70-70: Replaceconsole.logwith a proper logging mechanism
executeCircuitandoptimizeboth useconsole.log, which trips theno-consolerule and can clutter stdout in production.If you want to preserve these messages, consider:
- Using a shared logger abstraction, or
- Guarding logs behind a debug flag / environment check.
Otherwise, it’s safe to remove them once you’re confident in the flows.

packages/services/google-ai/index.ts (1)
73-83: Consider exposing a reset function for testing.The singleton pattern is acceptable for Node.js single-threaded execution but makes testing difficult since the instance persists across test cases.
Consider adding a reset function:
/** * Get Google AI manager */ export function getGoogleAI(): GoogleAIManager { if (!googleAIInstance) { googleAIInstance = new GoogleAIManager(); } return googleAIInstance; } +/** + * Reset singleton (for testing) + */ +export function resetGoogleAI(): void { + if (googleAIInstance) { + googleAIInstance.cleanup(); + googleAIInstance = null; + } +} + export default getGoogleAI;packages/services/google-ai/gemini-service.ts (2)
52-79: Consider using a structured logging framework.Static analysis flagged the
console.logstatements (lines 54, 69). While console logging is acceptable for a service layer, using a structured logging framework (e.g.,winston,pino) would provide better control over log levels, formatting, and output destinations in production.Consider this approach:
import { createLogger } from './logger'; // your logging utility export class GeminiService { private logger = createLogger('GeminiService'); async generate(request: GenerateRequest): Promise<GenerateResponse> { try { this.logger.info('Generating content...'); // ... existing code ... this.logger.info(`Generated ${text.length} characters`); return { text, finishReason }; } catch (error: any) { this.logger.error('Generation error:', error); throw error; } } }This applies to similar console statements at lines 86, 116, 135, and elsewhere in the file.
174-184: Factory function creates new instances without caching.The
createGeminiServicefactory creates a newGeminiServiceinstance on each call. This is fine sinceGoogleAIManager(inindex.ts) provides caching, but consider documenting this relationship to prevent misuse.Add a JSDoc comment:
/** * Create Gemini service from environment + * Note: Creates a new instance each time. Use GoogleAIManager.getGeminiService() + * for cached instances in most cases. */ export function createGeminiService(model?: GeminiConfig['model']): GeminiService {package.json (1)
170-202: Verify React/Ink/Playwright version compatibility and engine constraintsThe added devDeps and optional dependency look aligned with the new TUI and browser automation stack, but there are a couple of things worth double‑checking:
reactis pinned to^19.2.0whileink@^6.5.0has specific peer requirements; make sure Ink’s supported React range includes 19.x, or consider aligning to the currently supported major (often 18.x) to avoid peer‑dep warnings and subtle runtime issues.playwright@^1.48.0as an optional dependency is fine, but it’s a heavy install; confirm this version is what your Playwright service code is tested against.engines.nodealready enforces>=18.0.0, which satisfies the MCP server prerequisite in the coding guidelines; if you don’t need the upper bound, consider dropping<=24.0.0to avoid unnecessary install blocking on newer Node versions.As per coding guidelines
packages/core/protocols/mcp/types.ts (1)
43-79: Tighten MCP types to avoid pervasiveanyusageThe MCP type shapes are a solid start, but several fields currently use
any, which weakens type safety:
MCPContext.value,metadataMCPTool.inputSchemaMCPToolRequest.arguments,contextMCPToolResponse.result,metadataConsider narrowing these to
unknownor a JSON‑like type, or making the tool interfaces generic, e.g.:export type JSONValue = string | number | boolean | null | JSONValue[] | { [k: string]: JSONValue }; export interface MCPContext<T = JSONValue, M = Record<string, JSONValue>> { serverId: string; key: string; value: T; metadata?: M; createdAt: Date; expiresAt?: Date; }and similarly parameterize
MCPToolRequest/MCPToolResponseover argument and result shapes. This keeps the flexibility while honoring the “strongly‑typed configuration interfaces” goal.As per coding guidelines
packages/core/protocols/mcp/server-manager.ts (1)
13-203: Refine MCPServerManager logging, STARTING state handling, and config loader behaviorThe manager is a nice abstraction for MCP server lifecycle; a few small adjustments would make it more robust and lint‑friendly:
Logging vs. lint (
no-console)
Multipleconsole.log/console.errorcalls (e.g., lines 27, 62, 94, 114, 134, 144, 202) will keep tripping lint. It’d be cleaner to inject or import the project’s logger (pino/winston/etc.) and route messages through that instead ofconsole.Handling the
STARTINGstate instartServer
Right now,startServershort‑circuits only when status isRUNNING. If callers invokestartServertwice in quick succession, the second call will seeSTARTINGand attempt another start. TreatingSTARTINGas a no‑op (similar to RUNNING) would make the lifecycle idempotent and safer for concurrent callers.startAll/stopAll messaging
startAllandstopAlllog “All servers started/stopped” even when somestartServer/stopServercalls fail in the loop. Consider tracking failures and either summarizing them or adjusting the message to “Start sequence completed (N failed)” to avoid misleading logs.
loadMCPServersFromConfigstub clarity
The helper currently ignoresconfigPathand returns a hardcoded set of 5 servers. That’s fine as a stub, but it’d be good to either:
- Use
configPathwhen you wire up readinggemini-extension.json, or- Document clearly that the argument is currently unused and this is an in‑code default set.
These are incremental improvements; the overall design and public API look solid.
Also applies to: 209-256
packages/core/protocols/mcp/index.ts (1)
38-46: Optional: either use or underscore the unusedconfigPathparameter
loadMCPServersFromConfig('gemini-extension.json')passes a path argument, but the current implementation ofloadMCPServersFromConfig(configPath: string)ignores it and returns a hardcoded list. If this is intentional for now, consider prefixing the parameter with_configPathor adding a brief comment at the call site to clarify that the path is reserved for a future file-backed implementation, which will also keep strictnoUnusedParameterslinters happy.packages/core/protocols/ap2/transaction-manager.ts (1)
179-226: Optional: validate refund amounts and currency
refundTransactionallows a customrequest.amountbut does not validate that:
- The refund amount’s currency matches the original transaction.
- The refund amount does not exceed the original transaction amount (for partial refunds).
If AP2 should prevent over-refunds or cross-currency refunds, consider adding checks here similar to mandate validation, and fail early with a clear error if constraints are violated.
packages/core/protocols/a2a/agent-card.ts (2)
158-161: Replace rawconsole.logwith a shared logger (or disable the lint) for consistencyStatic analysis is flagging this
console.log, and the file usesconsolein several places. If the project has a centralized logging utility, it would be cleaner to route all A2A logs through that instead of directconsole.logcalls; alternatively, if these logs are intentionally lightweight, you may want to configure or suppress theno-consolerule for this module or the protocol layer.Aligning on one approach will keep lint noise down and make log handling consistent.
174-266: Gemini-Flow agent card is well-structured; consider tightening JSON schema typesThe predefined Gemini-Flow
AgentCardis nicely structured and advertises capabilities and protocols clearly. One small improvement would be to ensure theinputSchema/outputSchemafields align with yourJSONSchematype and any JSON Schema tooling you plan to use—for example, replacing nonstandardtype: 'any'with a union (e.g.,type: ['string', 'number', 'object', 'array', 'boolean', 'null']) or a project-specific extension if required.If your
JSONSchematype already supports'any'as a custom extension, you’re fine; otherwise, this change will prevent type/lint issues later.src/browser/services-config.ts (1)
106-139: Optional: narrow service name type for safer lookupsRight now
getServiceConfigand friends acceptserviceName: string. If these names are only ever drawn from a known set (the keys ofALL_SERVICES), you could tighten the API by introducing atype ServiceName = keyof typeof ALL_SERVICES;and using that ingetServiceConfig,requiresPlaywright, etc. That would catch typos at compile time instead of returningundefinedat runtime.Not critical, but a nice safety and DX improvement if call sites are all TypeScript.
src/browser/playwright-service-base.ts (2)
9-20: Tighten config and auth state typing for better IDE safety
PlaywrightServiceConfigand especiallyAuthenticationStateare quite loose (any[],any). It would be safer to leverage Playwright’s own types (e.g.cookies?: BrowserContext['cookies'] extends () => Promise<infer T> ? T : never, or explicitCookie[],storageState?: StorageState) so downstream services get proper intellisense and compile‑time checks.
41-67: Guard against uninitializedpage/browserand clarify auth state loading
waitForElementdereferencesthis.page!, andloadAuthStatesilently no‑ops ifbrowserhasn’t been created yet. In practice you always callinitialize()first, but a defensive guard (throwing a clear error ifbrowser/pageare null) would make misuse easier to diagnose and avoid obscureCannot read property ... of nullfailures later. Similarly, consider documenting or asserting thatloadAuthStatemust be called afterinitialize()or adding a helper that both launches the browser and loads auth state in one step.Also applies to: 87-95, 120-128
packages/core/protocols/ap2/mandate-manager.ts (2)
158-188: Mandate verification logic is correct but note status mutation side‑effect
verifyMandatecorrectly enforces status, expiry, currency, and maxAmount constraints, and it marks expired mandates asEXPIRED. That mutation is useful, but also means a pure “can I pay?” check has side effects; callers should be aware that repeated verification calls can transition state. If you need both behaviors, consider a side‑effect‑freeisMandateValid(...)helper that delegates to this logic without updating status.
266-282: ClarifycleanupExpiredsemantics (mark vs. remove) for maintainers
cleanupExpiredcurrently marks PENDING mandates asEXPIREDbut does not remove them from the map. That’s totally valid, but the name “cleanup” might suggest deletion to future readers. A brief doc comment (or optionally renaming tomarkExpiredMandates) would make the intended semantics explicit and avoid accidental double‑handling later.packages/core/protocols/a2a/communication.ts (1)
212-241: TaskExecutor lifecycle is coherent; minor logging considerations only
TaskExecutor’s handling ofsubmitTask,updateTaskStatus,cancelTask, andcleanupOldTasksis internally consistent: metrics are updated only on terminal states, and cleanup only prunes finished/old tasks. The additional console logging is helpful during development; if you later introduce a centralized logger for the rest of the protocol suite, this class is a good candidate to hook into it.Also applies to: 309-330
src/browser/service-orchestrator.ts (1)
19-32: Define strongly-typed Gemini/Vertex request and client interfaces to catch mismatched params at compile timeThe current code at lines 19–32 uses
anyforServiceRequest.paramsandconfig, and lines 163–185 and 190–208 acceptclient: any. This allows loose coupling but loses type safety on critical paths:
- In
executeGeminiAPI,request.paramscan be any shape—accessing.promptor.historyisn't validatedstartChat(request.params.history || [])andgenerateContent(request.params.prompt)assume structure that's never enforced- The
clientparameter hides whether it's aGoogleGenerativeAIorVertexAIinstanceUsing the SDK typings from
@google/generative-ai, create discriminated unions for Gemini requests and narrow client types:// Request types (discriminated union by service + action) export interface GeminiGenerateRequest { service: 'gemini-flash' | 'gemini-pro'; action: 'generate'; params: { prompt: string | { text: string }; temperature?: number }; } export interface GeminiChatRequest { service: 'gemini-flash' | 'gemini-pro'; action: 'chat'; params: { message: string; history?: any[] }; } export type ServiceRequest = GeminiGenerateRequest | GeminiChatRequest | /* Vertex, other services */; // Client type (narrowed per service) interface GeminiClientHandle { getGenerativeModel(params: { model: string }): any; // GenerativeModel from SDK // other methods as needed } // Usage: client is now typed and executeGeminiAPI receives narrowed type private async executeGeminiAPI(client: GeminiClientHandle, request: GeminiGenerateRequest | GeminiChatRequest): Promise<any>This prevents typos and shape mismatches at compile time rather than runtime. Apply similar patterns for Vertex AI.
src/browser/services/ai-studio-ultra.ts (5)
22-25: Type the service config instead of using an untyped{}defaultRight now
constructor(config = {})leavesconfigeffectively untyped, which makes it harder to know what options are supported and weakens TypeScript’s checks. Consider introducing an explicitAIStudioUltraConfig(or reusing the base Playwright config type) and using it here:export interface AIStudioUltraConfig { // e.g. headless?: boolean; // authStatePath?: string; } constructor(config: AIStudioUltraConfig = {}) { super('https://aistudio.google.com', 'AI Studio Ultra', config); }This keeps the public API self-documenting and prevents accidental misconfiguration.
65-96: Make the auth state path configurable or ensure the.authdirectory exists
authenticate()always writes to./.auth/aistudio-auth.json. If that directory doesn’t exist or the caller wants a different location (e.g., per-profile, per-environment), this can fail or be inconvenient.Two concrete improvements:
- Either ensure the directory exists before calling
saveAuthState, or- Accept an
authStatePathin the service config and default to the current path.This keeps the flow robust in more environments (CI, different working dirs, etc.).
101-120: AlignexecuteAction’sactionargument withparams.type
executeAction(action: string, params: AIStudioAction)logs theactionargument but branches entirely onparams.type. That makes it easy for callers to pass inconsistent values (e.g.,action='generate'butparams.type='chat').Either:
- Drop the
actionparameter and rely solely onparams.type, or- Enforce consistency (e.g., validate
action === params.typeand throw if they differ).This reduces ambiguity at the integration points.
125-168: Optional: consider centralizing logging to satisfyno-consolerulesThis method and others use
console.log/console.warn, which CodeFactor is flagging. If this file is part of a library or reused CLI, you might:
- Wrap logging in a small logger abstraction (or reuse an existing one), or
- Guard logs behind a debug flag.
That way you can keep the helpful traces without fighting
no-consolein linters.
226-245: Tighten parameter typing and handle all defined generation parameters
configureParameters(params: any)currently only setstemperature, even thoughAIStudioAction.parametersdeclarestopP,topK, andmaxTokenstoo, andparamsis untyped here.You could:
- Type it as
configureParameters(params: NonNullable<AIStudioAction['parameters']>), and- Gradually add handling for the remaining fields (even if some are
TODOplaceholders tied to specific UI selectors).That keeps the implementation aligned with the public type surface and makes it harder to accidentally pass unsupported keys.
packages/core/protocols/a2a/types.ts (1)
150-201: Consider JSON‑friendly timestamp types instead ofDatein protocol messagesTypes like
TaskMetrics.startTime/endTime, andNegotiationResponse.terms.expiresAtare currentlyDate. Since A2A messages are sent over JSON-RPC, callers will usually see ISO strings or epoch numbers on the wire, not actualDateinstances.To avoid confusion at boundaries, consider:
- Using
string(ISO 8601) ornumber(epoch ms) in the protocol types, and- Converting to
Datein internal/domain models when needed.This keeps the protocol layer strictly JSON-serializable and makes expectations clearer for remote agents.
packages/core/protocols/a2a/protocol-manager.ts (5)
51-58: Make endpoint override resilient to future changes in the self cardOverriding
this.selfCard.endpoints[0].urlassumes thatcreateGeminiFlowAgentCard()always returns at least one endpoint. If that function ever changes to return an empty array or reorder endpoints, this line can break.A slightly safer pattern:
if (this.config.endpoint) { if (this.selfCard.endpoints.length === 0) { this.selfCard.endpoints.push({ url: this.config.endpoint, protocol: 'http', transport: 'json-rpc' }); } else { this.selfCard.endpoints[0].url = this.config.endpoint; } }avoids hidden coupling to the card factory’s internal shape.
97-153: Error handling path is solid; consider logging structured errors for observability
handleIncomingRequestcorrectly maps unknown methods and internal failures into JSON-RPC error responses while only replying whenidis present (notifications). The basic flow looks good.If you’re planning to operate this in a distributed setup, you may want to augment the
catchblock with structured logging (e.g., includingrequest.methodandrequest.id) instead of—or in addition to—plainconsole.log/console.error, to make downstream tracing easier.
173-195: Negotiation handler currently ignores incoming requirement hints
handleNegotiationRequestonly checkshasCapabilityand then returns a fixedtermsobject; it doesn’t inspectparams.requirements(latency, cost, quality, constraints).That’s fine as an MVP, but it might surprise integrators who expect at least basic constraint honoring. A simple next step could be:
- Validating
maxLatency/maxCostagainst your static terms, and- Returning
accepted: falsewith a clearreasonwhen they can’t be met.This keeps the behavior predictable while you evolve toward a richer negotiation algorithm.
253-272:sendTaskcan safely return the locally generatedtaskId
sendTaskgenerates ataskId, sendstask.submit, then returnsresult.taskId. In a well‑behaved peer this will match, but relying on the remote to echo back your ID isn’t necessary and introduces a tiny coupling.Given you already construct the ID, you can simplify and harden this by:
await this.communicator.sendRequest(endpoint, 'task.submit', taskRequest); return taskId;The remote can still use the ID for its own tracking, and your callers get a stable value independent of peer behavior.
357-377: Clarify singleton behavior ofgetA2AProtocolin documentation
getA2AProtocol(config?)ignores any config passed after the first call because it reuses the existinga2aInstance. That’s a reasonable pattern, but it’s easy for consumers to assume later calls with new config will reconfigure the manager.It would be helpful to:
- Document this behavior explicitly, and/or
- Expose a dedicated initializer/reset function (you already have
resetA2AProtocol()) in the public docs for test setups and multi‑tenant scenarios.That will reduce subtle misconfigurations in larger deployments.
src/browser/services/google-labs.ts (5)
31-35: Give Labs services an explicit, shared config typeBoth
LabsFlowServiceandLabsWhiskServiceuseconstructor(config = {}), which makes the supported options opaque and weakens type safety.Consider defining a shared config interface (or reusing the base one), for example:
export interface LabsServiceConfig { // e.g. headless?: boolean; // authStatePath?: string; } constructor(config: LabsServiceConfig = {}) { super('https://labs.google.com/flow', 'Google Labs Flow', config); }This keeps the browser automation layer consistent and self-documenting.
79-96: Align FlowexecuteActionsignature with how actions are actually dispatchedSimilar to the Ultra service,
executeAction(action: string, params: LabsFlowAction)logsparams.typeand completely ignores theactionparameter when dispatching.To avoid confusion at call sites, either:
- Remove the
actionargument, or- Validate that
actionandparams.typematch and fail fast if they don’t.This makes the contract clearer for the orchestrator layer.
256-293: Image generation flow is reasonable; just be mindful of UI selector variability
generateImagedoes the right high-level steps: wait for a prompt input, fill it, optionally pick a style, click “Generate/Create”, wait for a generated image, and return its URL. That’s a solid baseline given the UI may evolve.As you refine this, consider centralizing selectors or making them configurable to reduce brittleness across UI updates, but the overall flow is sound.
295-316:editImage’s upload branch is currently a stubThe reference-image upload path:
if (params.referenceImage) { const uploadButton = await this.page!.$('input[type="file"], button:has-text("Upload")'); if (uploadButton) { await uploadButton.click(); // File upload logic } }does not actually set the file to upload. This is fine as a placeholder, but callers should be aware it won’t yet honor
referenceImage.You might want to either:
- Implement the upload (e.g., via
setInputFileson the file input), or- Temporarily document/annotate this as not yet supported to avoid surprising users.
59-76: Optional: centralize or gate console logging to satisfyno-consolerules
authenticate()(and other methods) log progress withconsole.log, which CodeFactor is flagging. If these services are reused in non-CLI contexts, consider routing logs through a shared logger or only enabling them in a debug mode so you can keep observability without tripping linters.packages/core/protocols/ap2/types.ts (1)
59-244: Prefer JSON‑native timestamp types for protocol messagesSeveral AP2 types (e.g.,
PaymentMandate.createdAt/expiresAt,PaymentTransaction.createdAt/completedAt,TransactionReceipt.timestamp,BalanceResponse.lastUpdated,RefundResponse.createdAt) currently useDate. Since these are protocol payloads that will usually move over JSON, consumers will see strings or numbers, not actualDateinstances.To avoid deserialization mismatches between agents:
- Consider representing these as
string(ISO 8601) ornumber(epoch ms) in the AP2 types, and- Converting to
Datein your internal domain model where needed.That keeps the cross-agent contract unambiguous while preserving strong typing.

Use environment-agnostic timeout type instead of NodeJS.Timeout
The pendingRequests map annotates timeout as NodeJS.Timeout, which ESLint flags (NodeJS not defined) and also ties this code to Node typings. You can avoid that by using the built-in ReturnType<typeof setTimeout>:
- private pendingRequests: Map<string | number, {
- resolve: (value: any) => void;
- reject: (error: any) => void;
- timeout: NodeJS.Timeout;
- }> = new Map();
+ private pendingRequests: Map<string | number, {
+ resolve: (value: any) => void;
+ reject: (error: any) => void;
+ timeout: ReturnType<typeof setTimeout>;
+ }> = new Map();This keeps the type accurate in both Node and browser-like environments and satisfies the linter.

Config flags are defined but not enforced anywhere
A2AProtocolConfig exposes enableDiscovery and enableNegotiation, but the manager doesn’t actually check these flags when handling methods like 'discovery' or 'negotiate'.
If these flags are meant to control surface area, consider:
- Short‑circuiting in
handleIncomingRequestwhen the corresponding feature is disabled (e.g., return aMETHOD_NOT_FOUNDerror), and/or - Reflecting the flags in the self agent card’s capabilities/metadata.
This will help avoid situations where configuration suggests a feature is off but the agent still responds as if it’s on.
🤖 Prompt for AI Agents
In packages/core/protocols/a2a/protocol-manager.ts around lines 36 to 45, the
constructor sets enableDiscovery and enableNegotiation but those flags are not
enforced; update the manager to (1) check these flags in request
handling—short‑circuit in handleIncomingRequest (or equivalent) and return a
METHOD_NOT_FOUND or feature-disabled error when a request for 'discovery' or
'negotiate' arrives while the respective flag is false, (2) avoid registering or
expose handlers for disabled features where registration happens, and (3)
reflect the flags in the self agent card/capabilities metadata so downstream
code sees the true surface area; implement minimal guard clauses and capability
updates to ensure config and runtime behavior stay consistent.

Align transaction state and response when execution fails
When an error occurs after a transaction has been created (e.g., during processPayment or executeMandate), the catch block:
- Returns a response with
transactionId: ''andstatus: FAILED. - Does not update any existing
PaymentTransactioninthis.transactionstoFAILED.
This can leave an in-memory transaction stuck in PENDING/PROCESSING while the caller sees a failed response with no ID, making tracking and recovery difficult.
You can track the created transaction and update it on failure, while returning its ID:
- async executePayment(request: PaymentRequest, from: PaymentAccount, to: PaymentAccount): Promise<PaymentResponse> {
- try {
+ async executePayment(
+ request: PaymentRequest,
+ from: PaymentAccount,
+ to: PaymentAccount
+ ): Promise<PaymentResponse> {
+ let transaction: PaymentTransaction | undefined;
+ try {
// Verify mandate
if (!this.mandateManager.verifyMandate(request.mandateId, request.amount)) {
return {
transactionId: '',
status: TransactionStatus.FAILED,
error: {
code: 'INVALID_MANDATE',
message: 'Mandate is not valid for this payment'
}
};
}

Make resetProtocols async to avoid racing cleanup
ProtocolManager.cleanup() is async, but resetProtocols() calls it and immediately nulls protocolManagerInstance without awaiting. In tests or long‑running processes, this can race MCP server shutdown and lead to subtle flakiness (e.g., ports still bound when a new instance starts).
Here’s a minimal change to make cleanup deterministic:
-/**
- * Reset all protocols (for testing)
- */
-export function resetProtocols(): void {
- if (protocolManagerInstance) {
- protocolManagerInstance.cleanup();
- protocolManagerInstance = null;
- }
-}
+/**
+ * Reset all protocols (for testing)
+ */
+export async function resetProtocols(): Promise<void> {
+ if (protocolManagerInstance) {
+ await protocolManagerInstance.cleanup();
+ protocolManagerInstance = null;
+ }
+}Call sites can then await resetProtocols() in teardown to ensure all protocol resources are released before re‑initializing.

resetMCPProtocol should await async cleanup to avoid races
MCPProtocol.cleanup() is async but resetMCPProtocol() neither returns a Promise nor awaits it. Callers invoking resetMCPProtocol() (especially tests) may assume cleanup is finished when it is still in progress, and any rejection from cleanup() would be unhandled.
Consider making resetMCPProtocol async and awaiting cleanup:
-export function resetMCPProtocol(): void {
- if (mcpInstance) {
- mcpInstance.cleanup();
- mcpInstance = null;
- }
-}
+export async function resetMCPProtocol(): Promise<void> {
+ if (mcpInstance) {
+ await mcpInstance.cleanup();
+ mcpInstance = null;
+ }
+}Call sites can then await resetMCPProtocol() when they need a fully cleaned-up state.

In packages/core/protocols/mcp/index.ts around lines 51-65 (and similarly adjust

resetMCPProtocol() for a fully completed cleanup, and update any internal call
sites/tests to await the new async function.

Fix minor inconsistencies in MCP and AP2 documentation
Two small doc mismatches to consider tightening up:
- Line 374+ says Gemini‑Flow integrates 9 MCP servers, but the bulleted list that follows only enumerates 8. Either add the missing server or adjust the count so readers aren’t confused.
- The
PaymentTransactiontype (lines 219–227) exposes anid: string, but later examples logpayment.transactionId. Either rename the field in the type or update examples to usepayment.idso consumers don’t reach for a non‑existent property.
Also applies to: 218-228
🤖 Prompt for AI Agents
In PROTOCOLS.md around lines 370 to 386, the MCP section incorrectly states "9
MCP servers" while listing only 8 — update the header count to "8" or add the
missing server to the enumerated list so the number and items match; also in
PROTOCOLS.md around lines 218 to 228, the PaymentTransaction type exposes an id:
string but examples reference payment.transactionId — either rename the type
field to transactionId or update all examples to use payment.id for consistency
(pick one convention and apply it across the type definition and all example
usages).

Wrap switch cases with const declarations to satisfy noSwitchDeclarations and avoid TDZ pitfalls
createAPIClient and executeGeminiAPI declare const bindings directly in case clauses. Linters/BIOME correctly flag this because those bindings share the switch scope and can create subtle temporal‑dead‑zone issues if refactored later.
You can fix this cleanly by wrapping each case’s body in its own block:
private async createAPIClient(serviceName: string): Promise<any> {
// Load appropriate SDK/client
switch (serviceName) {
- case 'gemini-flash':
- case 'gemini-pro':
- const { GoogleGenerativeAI } = await import('@google/generative-ai');
- const apiKey = process.env.GOOGLE_AI_API_KEY || process.env.GEMINI_API_KEY;
- if (!apiKey) {
- throw new Error('GOOGLE_AI_API_KEY or GEMINI_API_KEY environment variable required');
- }
- return new GoogleGenerativeAI(apiKey);
-
- case 'vertex-ai':
- const { VertexAI } = await import('@google-cloud/aiplatform');
- return new VertexAI({
- project: process.env.GOOGLE_CLOUD_PROJECT,
- location: process.env.GOOGLE_CLOUD_LOCATION || 'us-central1'
- });

const model = client.getGenerativeModel({
model: request.service === 'gemini-flash' ? 'gemini-2.0-flash-exp' : 'gemini-pro'
});
switch (request.action) {
- case 'generate':
- const result = await model.generateContent(request.params.prompt);
- const response = await result.response;
- return response.text();
-
- case 'chat':
- const chat = model.startChat(request.params.history || []);
- const chatResult = await chat.sendMessage(request.params.message);
- return chatResult.response.text();
+ case 'generate': {
+ const result = await model.generateContent(request.params.prompt);
+ const response = await result.response;

+ }
+
+ case 'chat': {
+ const chat = model.startChat(request.params.history || []);
+ const chatResult = await chat.sendMessage(request.params.message);

Guard listModels() against uninitialized page for consistency
Unlike checkAuthentication() and executeAction(), listModels() assumes this.page is initialized (this.page!) and will throw if it’s not.
To keep behavior consistent and fail fast with a clear message, consider adding the same guard:
if (!this.page) {
throw new Error('Page not initialized. Call initialize() first.');
}before querying selectors.

Error('Page not initialized. Call initialize() first.'); then proceed to query
DOM; this ensures fail-fast behavior and consistent error messaging across
methods.

Use imageUrl or drop it from downloadImage to avoid a misleading API
downloadImage(imageUrl: string, savePath: string) ignores imageUrl and just clicks a generic download button. That can confuse callers who expect the method to act on the provided URL.
Two options:
- Use
imageUrldirectly (e.g.,page.goto(imageUrl)first or validate it matches the selected image), or - Remove the
imageUrlparameter and rely purely on the current UI selection.
Either way, aligning the implementation with the signature will make the API more intuitive.
