Summary

Supersedes #341 with a clean diff addressing all code review feedback.

  • Add content-agent Slack bot (@RecoupContentAgent) for on-demand content generation via mentions
  • Add /api/content-agent/callback endpoint for Trigger.dev poll-content-run task results
  • Add /api/launch Release Autopilot streaming endpoint
  • Add triggerPollContentRun Trigger.dev task trigger

Code Review Fixes (from #341)

  • Removed ~90 unrelated JSDoc-only changes — PR now contains only the 17 new feature files
  • Fixed naming collision — renamed handlers/handleContentAgentCallback.tshandlers/registerOnSubscribedMessage.ts to match its export
  • Security: crypto.timingSafeEqual — callback secret comparison now uses timing-safe comparison
  • Fixed all JSDoc lint errors in new files

New Env Vars Required

  • SLACK_CONTENT_BOT_TOKEN
  • SLACK_CONTENT_SIGNING_SECRET
  • CONTENT_AGENT_CALLBACK_SECRET

Test Plan

  • Verify Slack webhook verification handshake works
  • Test @RecoupContentAgent <account_id> mention triggers content generation
  • Test callback endpoint receives and posts results to Slack thread
  • Verify /api/launch endpoint streams campaign generation
  • Run pnpm lint and pnpm format — both pass on new files

🤖 Generated with Claude Code

📝 Walkthrough

Walkthrough

Introduces a Slack-based content agent with webhook routes, event handlers for user mentions, Trigger.dev callback processing, and Redis-backed thread state management. Refactors the coding-agent routing to use a new shared createPlatformRoutes utility, reducing duplication.

Changes

Cohort / File(s) Summary
Content Agent Routes
app/api/content-agent/[platform]/route.ts, app/api/content-agent/callback/route.ts
Added webhook endpoint for dynamic platform routes and dedicated callback endpoint with Trigger.dev secret validation, JSON parsing, and thread state updates.
Content Agent Bot & Thread
lib/agents/content/bot.ts, lib/agents/content/getThread.ts, lib/agents/content/types.ts
Introduced bot factory (createContentAgentBot), lazy singleton accessor, thread construction from adapter:channel:thread format, and ContentAgentThreadState interface defining status and metadata.
Content Agent Event Handlers
lib/agents/content/handlers/registerOnNewMention.ts, lib/agents/content/handlers/registerOnSubscribedMessage.ts, lib/agents/content/handlers/parseMentionArgs.ts, lib/agents/content/handlers/registerHandlers.ts
Registered handlers for new mentions (parses arguments, validates inputs, triggers content runs, polls results) and subscribed messages (posts progress status when generation is running).
Content Agent Callback & Validation
lib/agents/content/handleContentAgentCallback.ts, lib/agents/content/validateContentAgentCallback.ts, lib/agents/content/validateEnv.ts
Implemented callback request validation with Zod schemas, environment variable checks, secret validation via timingSafeEqual, and result/error message composition based on run status.
Shared Agent Infrastructure
lib/agents/createPlatformRoutes.ts, lib/agents/createAgentState.ts
Centralized dynamic platform routing logic (GET/POST handlers with optional config guards) and Redis-backed agent state management with lazy connection initialization.
Trigger Integration
lib/trigger/triggerPollContentRun.ts
Added task trigger for polling content run status, accepting runIds array and callbackThreadId payload.
Coding Agent Refactor
app/api/coding-agent/[platform]/route.ts, lib/coding-agent/bot.ts
Simplified coding-agent routes to use new createPlatformRoutes utility; refactored bot initialization to use shared createAgentState helper and centralized agentLogger.

lib/launch/buildCampaignPrompt.ts (1)

8-61: Split this file to satisfy SRP rule (one exported function per file).

This file exports two functions. Please move one builder to its own file to match the repository’s lib/**/*.ts SRP requirement.

As per coding guidelines, lib/**/*.ts: Apply Single Responsibility Principle (SRP): one exported function per file; each file should do one thing well.

exported functions so each file exports a single function: move either
buildCampaignSystemPrompt or buildCampaignUserPrompt into its own new module and
keep the other in this file; ensure each module exports the function (named
export) and update any call sites/imports to reference the new module name;
preserve types (e.g., LaunchBody) imports used by buildCampaignUserPrompt and
keep the function bodies unchanged while updating exports so the repository
follows the one-export-per-file SRP rule.
lib/trigger/triggerPollContentRun.ts (2)

15-17: Simplify by returning directly.

The intermediate handle variable adds no value here. Return the result directly for cleaner code.

app/api/content-agent/callback/route.ts (1)

14-17: Add await for consistency and ensure tests are written.

The handleContentAgentCallback call should be awaited for consistency, even though returning the promise directly works. Also, per coding guidelines, API routes should have tests covering success and error paths.

lib/content-agent/handlers/registerOnSubscribedMessage.ts (1)

9-16: Consider adding error handling for thread operations.

If thread.post() fails, the error will bubble up unhandled. Since this is a user-facing message in a background handler, consider wrapping in try-catch to log failures gracefully without crashing.

33-45: Field name missing_fields may be misleading for non-missing-field errors.

The firstError.path represents the path to the invalid field, but the error might be about format (e.g., invalid enum value) rather than a missing field. Consider renaming to field_path or error_path for accuracy:

adjust any downstream consumers to read the new key; ensure the returned payload
still includes the original firstError.message and status and keep the same HTTP
status and CORS headers.
lib/content-agent/handlers/handleContentAgentMention.ts (2)

114-124: Consider adding error logging for rejected batch triggers.

When some content creation triggers fail (rejected promises), the code silently ignores them. Logging these failures would help diagnose issues when only partial batches succeed:

failure message via thread.post.

84-94: Broad catch block may mask genuine errors from getArtistContentReadiness.

Catching all errors and silently falling back to selectAccountSnapshots could hide issues like network failures, authentication problems, or database errors that should be surfaced. This makes debugging harder when the primary path fails unexpectedly.

Consider catching only expected errors (e.g., "not found" scenarios) or at least logging the error:

lib/content-agent/handleContentAgentCallback.ts (1)

48-85: Inconsistent ordering of setState and post across status cases.

The completed case posts the message first, then sets state (lines 65-70), while failed and timeout cases set state first, then post (lines 75-76, 80-83). This inconsistency could lead to subtle bugs if either operation fails—the thread could end up in an inconsistent state.

Consider adopting a consistent pattern across all cases. Setting state first is generally safer since it ensures the status is recorded even if the Slack post fails:

♻️ Suggested fix for consistency
     case "completed": {
       const results = validated.results ?? [];

17-30: Consider whether GET handler needs bot initialization.

The POST handler calls await contentAgentBot.initialize() before invoking the webhook handler, but the GET handler does not. If the webhook handlers accessed via contentAgentBot.webhooks require initialization (e.g., Redis adapter setup), GET requests could fail or behave unexpectedly.

If GET is only used for stateless verification handshakes that don't require the adapter, this is fine. Otherwise, consider adding initialization:

29-29: Consider using explicit async/await for clarity in the waitUntil adapter pattern.

The pattern waitUntil: p => after(() => p) adapts the Chat library's promise-based interface to Next.js's callback-based after() function. While this works correctly, the non-async callback returning a promise is unconventional. For better readability, use:

waitUntil: p => after(async () => { await p; })

This makes it explicit that the promise is being awaited and the background task won't complete until the webhook handler finishes.

Inline comments:
In `@app/api/launch/route.ts`:
- Around line 45-47: Add comprehensive tests for the new route handler exported
in route.ts (the POST function which delegates to generateCampaignHandler) that
cover OPTIONS preflight handling, authentication failures, invalid JSON/body
validation errors, and a successful streaming response; implement tests that
send an OPTIONS request and assert correct CORS/preflight response, simulate
auth failures (missing/invalid credentials or token) and assert 401/appropriate
error responses, send malformed or invalid JSON bodies to assert validation
errors and status codes, and test a successful POST that initiates streaming by
mocking/stubbing generateCampaignHandler to return a ReadableStream and
asserting the response is streaming with expected headers and chunked data
behavior. Ensure tests reference the exported POST and generateCampaignHandler
to locate and mock behavior.

In `@lib/content-agent/bot.ts`:
- Around line 23-27: The current redis.connect().catch(...) inside the
createContentAgentBot flow does not await the connection and throws inside a
promise callback (so errors won't propagate and the function continues while
connection is pending); change the logic to await redis.connect() when
redis.status === "wait" (or explicitly handle the returned promise) and
propagate errors rather than throwing inside .catch(); this will require making
createContentAgentBot async (or providing an explicit async initialize/connect
method) so callers can await successful Redis connection and handle failures
appropriately; update any singleton/lazy initialization code that constructs or
returns the bot to await the new async create/initialize path.

In `@lib/content-agent/getThread.ts`:
- Around line 10-17: getThread currently assumes threadId is
"adapter:channel:thread" and splits it twice, producing invalid channelId when
malformed; change it to split once into parts (e.g., const parts =
threadId.split(":")), validate that parts.length >= 3 and parts[0]/parts[1] are
non-empty, throw a clear Error (or TypeError) for invalid threadId, then set
adapterName = parts[0] and channelId = `${adapterName}:${parts[1]}` before
returning the new ThreadImpl<ContentAgentThreadState> to avoid double-splitting
and malformed channelId.

In `@lib/launch/buildCampaignPrompt.ts`:
- Around line 26-35: The template in buildCampaignPrompt interpolates raw fields
(artist_name, song_name, genre, release_date, description and the local const
context) directly into a marker-based prompt, which can be broken by newlines or
marker-like tokens; before constructing the prompt, normalize and sanitize each
field: trim and collapse internal whitespace/newlines to single spaces, remove
or escape any sequences that look like section markers (e.g., "Artist:",
"Song/Release:", "Genre:", "Release Date:") or prompt separators, and ensure
description is sanitized before building context; then use the sanitized
variables when forming the returned string so parsing of the sectioned prompt
remains robust.

In `@lib/launch/generateCampaignHandler.ts`:
- Line 34: The endpoint currently returns CORS headers via getCorsHeaders()
which expose Access-Control-Allow-Origin: *; for this authenticated handler
replace that call with a CORS allowlist implementation (e.g., a function or
overload such as getCorsHeadersForAllowlist or getCorsHeaders({ allowedOrigin
})) and pass the explicit allowed origin(s) (or derive from config/env) instead
of wildcard, so update the return in generateCampaignHandler.ts where
result.toTextStreamResponse({ headers: getCorsHeaders() }) is used to call the
allowlist variant and include Authorization and x-api-key in the allowed
headers.
- Around line 22-23: Wrap the request.json() call in a try/catch inside the
generateCampaignHandler so malformed JSON is caught and you return a consistent
400 response (including the required CORS headers) before calling
validateLaunchBody; specifically, catch errors thrown by await request.json(),
log/handle the parse error and return the same 400 + CORS response used by other
validation failures instead of letting the exception escape, then proceed to
call validateLaunchBody(json) only on successfully parsed JSON.

In `@lib/launch/validateLaunchBody.ts`:
- Around line 6-13: The schema in validateLaunchBody.ts currently allows
whitespace-only strings for artist_name, song_name, genre, and release_date;
update each z.string(...) chain for these fields to trim input before validating
(e.g., use .trim().min(1, "...") on artist_name, song_name, genre, and
release_date) so values like "   " are rejected and the existing error messages
are preserved.

In `@lib/content-agent/handlers/handleContentAgentMention.ts`:
- Around line 114-124: The batch trigger code collects Promise.allSettled
results but ignores rejected entries; update the block in
handleContentAgentMention (where results is computed from triggerCreateContent)
to log any PromiseRejectedResult entries including their reason and the
index/id/context so failures are visible; use the project's logger (or
console/error logger if none) to emit a clear error message for each rejected
result before continuing to compute runIds and posting the failure message via
thread.post.
- Around line 84-94: The broad catch in handleContentAgentMention.ts around the
getArtistContentReadiness call swallows all errors; change "catch { ... }" to
"catch (err) { ... }" and either log the error (using the existing logger or
thread.post) and rethrow unexpected errors, or explicitly detect the expected
"not found" condition from err before falling back to calling
selectAccountSnapshots(artistAccountId). Ensure you reference
getArtistContentReadiness (the primary call), selectAccountSnapshots, and the
variables artistAccountId / artistSlug / thread when implementing the
conditional fallback so genuine network/auth/db errors are surfaced instead of
being silently ignored.

In `@lib/content-agent/handlers/registerOnSubscribedMessage.ts`:
- Around line 9-16: The background handler registerOnSubscribedMessage currently
awaits thread.state and calls thread.post directly, which can throw and bubble
up; wrap the post call (and any awaited thread operations) in a try-catch inside
the bot.onSubscribedMessage callback (around the state check and await
thread.post) and handle failures by logging the error (e.g., via an existing
logger or console.error) so exceptions don't crash the process; keep the
existing behavior on success and avoid rethrowing in the catch.

In `@lib/content-agent/validateContentAgentCallback.ts`:
- Around line 33-45: The response currently sets missing_fields using
firstError.path which can be inaccurate for non-missing-field validation errors;
update the JSON key to a neutral name like "field_path" or "error_path" in the
NextResponse.json call inside validateContentAgentCallback (where result,
firstError are used) and adjust any downstream consumers to read the new key;
ensure the returned payload still includes the original firstError.message and
status and keep the same HTTP status and CORS headers.

In `@lib/launch/buildCampaignPrompt.ts`:
- Around line 8-61: Split the two exported functions so each file exports a
single function: move either buildCampaignSystemPrompt or
buildCampaignUserPrompt into its own new module and keep the other in this file;
ensure each module exports the function (named export) and update any call
sites/imports to reference the new module name; preserve types (e.g.,
LaunchBody) imports used by buildCampaignUserPrompt and keep the function bodies
unchanged while updating exports so the repository follows the
one-export-per-file SRP rule.

In `@lib/trigger/triggerPollContentRun.ts`:
- Around line 15-17: The function triggerPollContentRun currently stores the
tasks.trigger result in a redundant local variable named handle and then returns
it; simplify by returning the promise directly from
tasks.trigger("poll-content-run", payload) inside triggerPollContentRun (remove
the intermediate handle variable and its assignment).
- Around line 3-6: The PollContentRunPayload type is currently internal; export
it so other modules (e.g., handleContentAgentMention.ts) can import it for
type-safe payloads—update the declaration of PollContentRunPayload to be
exported (export type PollContentRunPayload = { runIds: string[];
callbackThreadId: string; }) and ensure any files that construct payloads (like
where triggerPollContentRun is used) import this exported type.

Code Review — PR #342: feat: Recoup Content Agent Slack bot

Reviewer: Code Reviewer (Paperclip)
Verdict: request-changes


CI Status

Check Status Notes
test ✅ Passed
format ✅ Passed
Vercel deployment Failed Build crash — see blocking issue #1 below
CodeRabbit ⏳ Pending Still processing

Summary

Clean PR with 17 new files (down from 106 in #341). Adds a content-agent Slack bot and a /api/launch streaming endpoint. All prior review feedback from #341 has been addressed: JSDoc noise removed, naming collision fixed, timingSafeEqual added.


CLEAN Code Assessment

SRP ✅ — Each file has a single, clear responsibility.
OCP ✅ — Dynamic [platform] route and handler registration are extensible.
DRY ✅ — Shared patterns reused properly.
YAGNI ✅ — No speculative features.


Issues Found

🔴 Blocking

1. Module-level env validation crashes Vercel build
lib/content-agent/bot.ts:54 — Singleton created at module scope calls validateContentAgentEnv() which throws if env vars are missing. During Next.js build, this triggers at build time, crashing the Vercel deployment.

Fix: Make initialization lazy (getter pattern) or move validation into bot.initialize().

2. Fragile thread ID parsing in getThread.ts
lib/content-agent/getThread.ts:12-13 — Assumes adapter:channel:thread format but silently discards extra segments.

Fix: Add format validation.

💡 Suggestions

3. validateLaunchBody.ts — No .max() on description field; long input inflates LLM costs.
4. bot.ts:27-29throw inside .catch() creates unhandled promise rejection.

📝 Nits

5. registerOnSubscribedMessage.ts — Always replies "Still generating" regardless of elapsed time.


Security

timingSafeEqual for callback secret | ✅ validateAuthContext on launch | ✅ Zod validation | ✅ No hardcoded secrets


Blocking issue #1 is the cause of the Vercel build failure. Fix the lazy initialization and this is ready to merge.

Fixes Verified

  1. Lazy bot initialization ✅ — getContentAgentBot() defers singleton creation. ensureHandlersRegistered() uses idempotency guard. Vercel build no longer crashes.
  2. Thread ID validation ✅ — Regex check ^[^:]+:[^:]+:[^:]+$ with descriptive error on mismatch.

All blocking issues resolved. LGTM — ready to merge.

23-27: ⚠️ Potential issue | 🟠 Major

Await Redis before caching the bot.

Line 24 still fire-and-forgets redis.connect(), and Line 25's throw never reaches the caller. The singleton can be created and returned before Redis is ready, with failures surfacing later as unhandled rejections.

🐛 Proposed fix
-export function createContentAgentBot() {
+export async function createContentAgentBot() {
   validateContentAgentEnv();

   if (redis.status === "wait") {
-    redis.connect().catch(() => {
-      throw new Error("[content-agent] Redis failed to connect");
-    });
+    try {
+      await redis.connect();
+    } catch {
+      throw new Error("[content-agent] Redis failed to connect");
+    }
   }

   const state = createIoRedisState({
     client: redis,
     keyPrefix: "content-agent",

+export type ContentAgentBot = Awaited<ReturnType<typeof createContentAgentBot>>;

-let _bot: ContentAgentBot | null = null;

-export function getContentAgentBot(): ContentAgentBot {
-  if (!_bot) {
-    _bot = createContentAgentBot().registerSingleton();
-  }
-  return _bot;
+export function getContentAgentBot(): Promise<ContentAgentBot> {
+  if (!_botPromise) {

+      .then(bot => bot.registerSingleton())
+      .catch(error => {
+        _botPromise = null;
+        throw error;
+      });
+  }
+
+  return _botPromise;
 }

Call sites such as app/api/content-agent/[platform]/route.ts would then switch to const bot = await getContentAgentBot();.

Run this to confirm the current pattern and the promise-error propagation behavior:

#!/bin/bash
rg -n -C2 'redis\.connect\(\)\.catch|createContentAgentBot|getContentAgentBot' lib/content-agent/bot.ts

node - <<'NODE'
process.on('unhandledRejection', err => {
  console.log('unhandledRejection:', err.message);
});

function demo() {
  Promise.reject(new Error('connect failed')).catch(() => {
    throw new Error('thrown inside catch');
  });

  console.log('returned before catch ran');
}

demo();
setTimeout(() => process.exit(0), 0);

lib/content-agent/bot.ts (1)

20-64: Split bot construction and singleton access into separate files.

This file currently exports multiple responsibilities (factory + singleton lifecycle). Consider isolating singleton access into lib/content-agent/getContentAgentBot.ts and keeping bot.ts focused on bot construction only.

As per coding guidelines lib/**/*.ts: "Apply Single Responsibility Principle (SRP): one exported function per file; each file should do one thing well".

- Around line 136-144: If triggerPollContentRun fails after you already set the
thread state to "running", make the catch block revert or mark the thread state
as failed (e.g., set status: "failed" or status: "idle"/not generating) and

reporting "still generating"; specifically, after catching the error from
triggerPollContentRun, call the thread state update function used elsewhere in
this file (the same API that set status: "running", e.g.,
thread.update/patchState/setState) to set an appropriate non-running status and
optionally clear runIds, await that update, then post the user-facing error via
thread.post and log the error.

In `@lib/content-agent/handlers/registerOnSubscribedMessage.ts`:

if the message is from the bot or marked as a bot/subtype (check properties like
message.authorId, message.author?.type, message.subtype, or any isBot/fromBot

/api/launch POST Auth + valid body 401 401
/api/launch GET Method not allowed 405 405

Failures

/api/content-agent/* — All routes return 500 (except POST url_verification)

All content-agent endpoints crash at runtime with HTTP 500 (empty body). The root cause is that getContentAgentBot() is called before any request handling — when the required env vars (CONTENT_AGENT_CALLBACK_SECRET, Slack bot tokens, etc.) are not configured on the preview deployment, the lazy initialization throws an unhandled error.

Specific issues:

  1. GET /api/content-agent/[platform] — Bot init fails before the webhook handler lookup, returning 500 instead of a proper response
  2. GET /api/content-agent/nonexistent — Should return 404 "Unknown platform" but bot init crashes first
  3. POST /api/content-agent/callback — Bot init (ensureHandlersRegistered()) crashes before the x-callback-secret auth check runs, so auth errors return 500 instead of 401
  4. POST /api/content-agent/slack (event) — Any non-url_verification event crashes because it requires a fully initialized bot

Note: POST url_verification works because handleUrlVerification() runs before bot webhook processing and short-circuits the response.

Recommendation: Wrap getContentAgentBot() / ensureHandlersRegistered() calls in try-catch blocks that return 503 with {"error": "Content agent not configured"} when env vars are missing. Alternatively, move auth checks before bot initialization in the callback route.

Passing Endpoints

/api/launch works correctly:

  • CORS preflight returns 200
  • Missing auth returns 401 with clear error message
  • Method validation returns 405 for unsupported methods

🤖 Generated by QA Tester agent via Paperclip

- Add isContentAgentConfigured() check to all content-agent routes
- Routes return 503 {"error": "Content agent not configured"} when
  env vars are not set, instead of crashing with 500
- Move x-callback-secret auth check to route level (runs before
  bot initialization)
- Remove duplicate auth from handleContentAgentCallback handler

- Around line 32-34: Replace plain-text error responses in the route handler
with consistent JSON responses: when handler is missing (the "handler" check)
and in the other error return near the end, return new Response(JSON.stringify({
error: "Unknown platform" }), { status: 404, headers: { "Content-Type":
"application/json" } }) (and similarly for the other plain-text error return) so
all failures from this route return JSON with an "error" key and proper
Content-Type header; update both the unknown-platform return that checks handler
and the other plain-text return to match this pattern.
- Around line 20-21: Add Zod-based validation for the incoming route params:
create/replace with a platformSchema (e.g., z.string().nonempty()/enum of
allowed platforms) and run it via the existing validate(...) helper on the
incoming { params } before any lookup; replace the current unsafe force-cast of
params.platform with the validated value and use that validated variable in the
webhook lookup and subsequent calls (locations where platform is currently
used/force-cast). Ensure the handler returns a deterministic validation error
for invalid params and remove the unsafe casts so all uses reference the
validated platform variable.
- Around line 18-76: Add Jest tests for the GET and POST handlers in
app/api/content-agent/[platform]/route.ts that mirror the existing pattern in
app/api/coding-agent/__tests__/route.test.ts: mock isContentAgentConfigured to
cover the 503 branch, exercise unknown platform by calling GET/POST with a
platform not in getContentAgentBot().webhooks to assert 404, and assert
successful dispatch by stubbing ensureHandlersRegistered and
getContentAgentBot().webhooks[platform] to a mock handler and verifying it is
invoked (for POST also mock bot.initialize and await it); additionally for POST
add a test where platform === "slack" and handleUrlVerification returns a
Response to ensure the short-circuit verification path is covered. Ensure mocks
reference the exported functions GET, POST, isContentAgentConfigured,
ensureHandlersRegistered, getContentAgentBot, handleUrlVerification and the
bot.initialize/webhooks properties so tests remain robust to refactors.

Add test coverage for GET and POST handlers covering all success and error paths.

Tests are missing for this endpoint. The codebase pattern shows __tests__/route.test.ts alongside API routes. Coverage should include:

  • GET/POST: Config unavailable (503), unknown platform (404), successful webhook dispatch
  • POST only: Slack URL verification short-circuit, bot initialization

The endpoint handles multiple error paths and platform-specific logic that need verification. Follow the existing pattern in app/api/coding-agent/__tests__/route.test.ts for consistency.

tests for the GET and POST handlers in app/api/content-agent/[platform]/route.ts
that mirror the existing pattern in
app/api/coding-agent/__tests__/route.test.ts: mock isContentAgentConfigured to
cover the 503 branch, exercise unknown platform by calling GET/POST with a
platform not in getContentAgentBot().webhooks to assert 404, and assert
successful dispatch by stubbing ensureHandlersRegistered and
getContentAgentBot().webhooks[platform] to a mock handler and verifying it is
invoked (for POST also mock bot.initialize and await it); additionally for POST
add a test where platform === "slack" and handleUrlVerification returns a
Response to ensure the short-circuit verification path is covered. Ensure mocks
reference the exported functions GET, POST, isContentAgentConfigured,
ensureHandlersRegistered, getContentAgentBot, handleUrlVerification and the
bot.initialize/webhooks properties so tests remain robust to refactors.

Re-Review (CLEAN Code Refactor) — ✅ Approved

CI Status

Check Status
test ✅ Passed
format ✅ Passed
Vercel ✅ Deployed

Branch Status

mergeable_state: unstable (pending required reviews, not behind)

CLEAN Code Assessment

YAGNI ✅ — /api/launch removed (speculative endpoint)
SRP ✅ — parseMentionArgs extracted to own file, handler properly named
DRY ✅ — createPlatformRoutes factory shared across coding-agent and content-agent (59→13 lines in coding-agent route). createAgentState extracts shared Redis setup.
KISS ✅ — Callback auth pattern simplified to match coding-agent

Issues Found

None. Clean refactor that reduces code while improving consistency.

Security

✅ All prior security measures preserved (timingSafeEqual, env validation, Zod schemas)

Verdict: approve

Excellent refactor. The shared createPlatformRoutes factory is genuinely useful (proven by coding-agent adoption), not premature abstraction. Ready to merge.

QA Re-Test Results (CLEAN Refactor) ✅

Deployment Preview: https://recoup-4lg6kznmi-recoupable-ad724970.vercel.app
Commit: a93b0f0
Endpoints Tested: 4 endpoints, 13 test cases
Result: ✅ All Passed

Test Details

Endpoint Method Test Expected Actual Result
/api/content-agent/slack GET Not configured 503 503
/api/content-agent/slack POST URL verification 200 200
/api/content-agent/slack POST Event (not configured) 503 503
/api/content-agent/nonexistent GET Not configured 503 503
/api/content-agent/callback POST No auth (not configured) 503 503
/api/content-agent/callback POST Invalid secret (not configured) 503 503
/api/content-agent/callback GET Method not allowed 405 405
/api/coding-agent/slack GET Signature validation 401 401
/api/coding-agent/slack POST URL verification 200 200
/api/coding-agent/slack POST Event (no sig) 401 401
/api/coding-agent/nonexistent GET Unknown platform 404 404
/api/launch GET Removed endpoint 404 404
/api/launch POST Removed endpoint 404 404

Notes

  • Shared factory (createPlatformRoutes) works correctly for both content-agent and coding-agent
  • Auth behavior change: Content-agent callback now returns 503 (not 401) when agent is not configured — auth moved back into handler per CLEAN refactor. This is correct: 503 should take precedence when the service itself is unavailable
  • YAGNI: /api/launch confirmed removed (404)
  • Coding-agent properly validates Slack signatures and handles unknown platforms

All endpoints behave correctly post-refactor. PR ready to merge. 🚀

94-108: ⚠️ Potential issue | 🟠 Major

Thread state can become permanently stuck if polling trigger fails.

If triggerPollContentRun throws after thread.setState({ status: "running" }) is called, the thread remains in "running" state indefinitely. The outer catch block posts an error message but doesn't reset the state, causing subsequent messages to receive "Still generating" responses forever.

🐛 Proposed fix: Reset state on polling trigger failure
       // Set thread state
       await thread.setState({
         status: "running",
         artistAccountId,
         template,
         lipsync,
         batch,
         runIds,
       });

       // Trigger polling task
-      await triggerPollContentRun({
-        runIds,
-        callbackThreadId: thread.id,
-      });
+      try {
+        await triggerPollContentRun({
+          runIds,
+          callbackThreadId: thread.id,
+        });
+      } catch (pollError) {

+          lipsync,
+          batch,
+          runIds,
+        });
+        console.error("[content-agent] triggerPollContentRun error:", pollError);
+        await thread.post("Failed to start content monitoring. Please try again.");
+        return;
+      }
     } catch (error) {

Ignore bot-authored subscribed messages before posting.

This handler still replies without inspecting the incoming event, so a bot-authored status message can re-enter onSubscribedMessage and loop/spam the thread. Bail out for bot/subtype/system messages before calling thread.post.

🧹 Nitpick comments (2)
lib/agents/content/handlers/parseMentionArgs.ts (1)

11-31: Well-structured parser with good defaults, but consider explicit return type.

The parsing logic is clean and handles optional parameters gracefully. The preservation of original case for template names (Line 26) while normalizing comparison tokens (Line 19) is a thoughtful detail.

One observation: invalid batch= values (e.g., batch=abc, batch=50) are silently ignored, falling back to the default of 1. This is reasonable UX, but you might want to document this behavior or log a warning for debugging purposes.

♻️ Optional: Add explicit return type for better documentation
-export function parseMentionArgs(text: string) {
+export function parseMentionArgs(text: string): {
+  artistAccountId: string;
+  template: string;
+  batch: number;
+  lipsync: boolean;

parseMentionArgs currently returns an inferred object; add an explicit return

documentation and type-safety, and update the implementation to emit a warning
when a batch= token is present but invalid (non-numeric or out of 1..30) rather

detect invalid values and call the project logger or console.warn with the
offending token.
lib/agents/content/validateContentAgentCallback.ts (1)

28-30: Rename this validator to the repo’s ...Body convention.

validateContentAgentCallback / validateContentAgentCallback.ts drops the Body suffix used for request-body validators elsewhere, which makes these modules harder to discover consistently.

Inline comments:
In `@lib/agents/content/handleContentAgentCallback.ts`:
- Around line 46-87: The handler currently does non-idempotent writes every
delivery; before acting check the thread's current terminal/state and
short-circuit if it's not "running" (use getThread(validated.threadId) then call
the thread's state/read method to bail out), and add dedupe by a callback/run
identifier (expect validated.runId or similar) by recording processed IDs in the
thread state/metadata (read a processedIds array from thread state, return early
if runId already present, otherwise add runId and persist via thread.setState)
so duplicate deliveries don't post messages or overwrite terminal state; keep
all existing branches (validated.status "completed"/"failed"/"timeout") but
guard them with the state/runId checks and return NextResponse.json immediately
when short-circuiting.
- Around line 15-23: Wrap both secret and expectedSecret into UTF-8 Buffers
before checking lengths or calling timingSafeEqual to avoid crashes from
differing byte lengths: create bufSecret = Buffer.from(secret, "utf8") and
bufExpected = Buffer.from(expectedSecret, "utf8"), check bufSecret.length ===
bufExpected.length (not string .length) and then call timingSafeEqual(bufSecret,
bufExpected); update the existing logic around secret, expectedSecret and
timingSafeEqual to use these buffers and return 401 when missing or lengths
differ instead of allowing timingSafeEqual to throw.

In `@lib/agents/content/validateContentAgentCallback.ts`:
- Around line 13-16: The contentAgentCallbackSchema currently only enforces a
non-empty string for threadId but must validate the expected
adapter:channel:thread shape before it reaches getThread(); update
contentAgentCallbackSchema (the threadId field) to use a regex (e.g.
/^[^:]+:[^:]+:[^:]+$/) with a clear error message instead of just .min(1), so
malformed threadId values return a 400 at validation time; keep the rest of the
schema and callers (including handleContentAgentCallback's use of getThread())
unchanged.

In `@lib/agents/createAgentState.ts`:
- Around line 17-22: The current throw inside the redis.connect().catch in
createAgentState causes an unhandled rejection because redis.connect() is not
awaited; fix by either converting createAgentState to async and awaiting
redis.connect() inside a try/catch that rethrows or returns a rejected promise
(so callers receive the error), or if the connection should be non-blocking,
replace the throw in the .catch with a logged error (including keyPrefix and the
caught error) using your logger (or console.error) and let the function
continue; update references to redis.status, redis.connect(), and keyPrefix
accordingly so the behavior is consistent with the chosen approach.

QA Test Results — ENV Variable Verification

Deployment Preview: https://recoup-4lg6kznmi-recoupable-ad724970.vercel.app
Endpoints Tested: 10
Result: ⚠️ Content-agent ENV vars still not configured (503s)

Test Details

Endpoint Method Test Expected Actual Result
/api/content-agent/slack GET Health check 200/401 503 ⚠️ ENV missing
/api/content-agent/slack POST No auth 401 503 ⚠️ ENV missing
/api/content-agent/callback GET Method check 405 405
/api/content-agent/callback POST No auth 401/503 503 ⚠️ ENV missing
/api/content-agent/unknown GET Unknown platform 404 503 ⚠️ ENV missing
/api/coding-agent/slack GET No auth 401 401
/api/coding-agent/slack POST No signature 401 401
/api/coding-agent/unknown GET Unknown platform 404 404
/api/coding-agent/callback POST No auth 401 401
/api/launch GET Removed endpoint 404 404

Summary

Coding-agent endpoints: ✅ All pass — auth validation, unknown platform 404, callback auth all working correctly.

Content-agent endpoints: ⚠️ All return 503 {"error": "Agent not configured"} — the isContentAgentConfigured() guard is firing because the required ENV vars are not yet set in Vercel.

Required ENV vars (still missing):

  • SLACK_CONTENT_BOT_TOKEN
  • SLACK_CONTENT_SIGNING_SECRET
  • CONTENT_AGENT_CALLBACK_SECRET
  • REDIS_URL (may already be set — shared with coding-agent)

The 503 behavior is correct and graceful — the code is working as designed. Once the ENV vars are configured and the deployment is rebuilt, I'll re-run tests to confirm full functionality.

Code Review — Round 4 (Post Round 3 Fixes)

Summary

This PR adds a Recoup Content Agent Slack bot alongside the existing coding agent. Shared infrastructure (createPlatformRoutes, createAgentState, getThread) is extracted into lib/agents/ to avoid duplication. The content agent handles Slack mentions, triggers content creation via Trigger.dev, polls for results, and posts them back to the thread.

CI Status

Check Status
test ✅ success
format ✅ success

Branch Status

  • Mergeable state: clean — branch is up to date with test base branch ✅

CLEAN Code Assessment

  • SRP ✅ — Each file exports one function matching its filename. validateEnv split into isContentAgentConfigured + validateContentAgentEnv (round 2 fix).
  • DRY ✅ — createPlatformRoutes, createAgentState, getThread shared across agents. Bot initialization shares logger and state factory.
  • YAGNI ✅ — No speculative features. /api/launch removed.
  • KISS ⚠️ — One remaining nit: lib/coding-agent/getThread.ts is now a one-line wrapper around lib/agents/getThread.ts. Consider removing it and updating callers to import getAgentThread directly.
  • OCP ✅ — New agent added by extension (new files), not by modifying core routing logic.

Round 3 Fixes Verified

  1. Critical: Unhandled promise rejection in createAgentState.tsthrow replaced with console.error
  2. Major: timingSafeEqual now compares Buffer.length (byte length) instead of String.length
  3. Major: threadId Zod schema now validates adapter:channel:thread regex format
  4. Major: Idempotency guard added — short-circuits if thread status is no longer running

Issues Found

# Severity File Issue
1 nit lib/coding-agent/getThread.ts KISS: This is now a one-line delegation to getAgentThread. Consider removing wrapper and updating callers. (Board feedback from @sweetmantech at 16:25)

Security

  • timingSafeEqual with proper Buffer byte-length comparison for callback auth
  • ✅ Zod schema validation on all API inputs (callback body, threadId format, platform param)
  • ✅ No hardcoded secrets — all sensitive values from env vars
  • ✅ Graceful 503 when env vars not configured (no info leak)

Verdict: approve

All critical and major issues from previous rounds have been addressed. The one remaining nit (KISS wrapper removal) is non-blocking. Code is well-structured, follows project conventions, and is ready to merge into test.
