Do not stop after only one or two commands. - ---- - -## Agent Workflow Guidelines - -### Starting New Work - -1. Create a branch from `main` - - ```bash - git switch -c / - ``` - -2. Implement the change -3. Add or update tests -4. Run full validation -5. Commit and push -6. Open a PR -7. Stay with the PR until checks finish or failures are fixed - -### Branch and PR Discipline - -- Never commit directly to `main` -- Never stop at `git push` -- Opening the PR is not the end of the task -- The task includes watching CI, fixing failures, and responding to review comments - ---- - -## PR Workflow - -### Default PR Sequence - -```bash -git switch -c / - -# make changes - -npm run lint -npm test -npx tsc --noEmit -npm run build - -git add . -git commit -m "" -git push --set-upstream origin / -PR_URL=$(gh pr create --fill) -gh pr checks "$PR_URL" -``` - -### CI Check Loop: Use It Aggressively - -After opening the PR, you must keep checking GitHub checks. The default pattern in this repo should be explicit re-checks with `sleep` and `gh`. - -Any new push resets this process. After **every** push, treat prior CI state as stale, then restart the check loop from the latest commit. - -For follow-up pushes to an existing PR, the default mental model is: - -```bash -git push && sleep 300 && gh pr checks "$PR_URL" -``` - -That shorthand means "push, wait, then verify the latest PR state." Do not treat `git push` alone as completion. - -Use this pattern repeatedly: - -```bash -gh pr checks "$PR_URL" -sleep 300 && gh pr checks "$PR_URL" -sleep 300 && gh pr checks "$PR_URL" -``` - -If checks are still running, keep going. If checks fail, investigate immediately and push a fix. Do not assume someone else will watch CI later. - -Do not stop after the first green snapshot if you just pushed. A fresh push can still produce a later failure, and it can also attract new bot or human review comments after CI restarts. - -`gh pr checks "$PR_URL" --watch` is useful, but the baseline expectation is still the explicit `sleep 300 && gh pr checks "$PR_URL"` re-check pattern because it works well for long-running CI and makes the agent verify completion instead of guessing. - -If your terminal tooling launches long-running commands through an async exec session, do not fire-and-forget the `sleep 300 && gh pr checks "$PR_URL"` command. Keep the same session alive and poll it until it exits so the agent actually waits for the delayed check to finish. - -### Merge Readiness - -Do not merge until all of the following are true: - -- All required checks are green -- Any failing checks were investigated and fixed -- Review comments are answered -- Unresolved conversations are handled -- The latest pushed commit has been re-checked after CI completed - -This final re-check matters: - -```bash -sleep 300 && gh pr checks "$PR_URL" -``` - -Use it before treating the PR as merge-ready. - ---- - -## Responding to PR Reviews - -### Review Handling Rules - -For each review thread, do one of the following: - -- Apply the requested change, push it, and reply with what changed -- Or explain clearly why the suggestion is being deferred or declined - -Do not leave review threads unacknowledged. -Do not push a review fix without also doing the post-push wait-and-check cycle. - -### Suggested Review Workflow - -```bash -gh pr view --json reviews -gh pr checks "$PR_URL" -``` - -After pushing a review fix: - -```bash -git push && sleep 300 && gh pr checks "$PR_URL" -``` - -Keep the `&&` guard, or use an equivalent conditional form.

Preserve rate-limit and not-found behavior -3. Keep authenticated GraphQL paths and unauthenticated fallbacks aligned -4. Update unit tests in `src/lib/__tests__/` - -### Change Card Rendering - -1.

Implement the change -3. Add or update tests -4. Run full validation -5. Commit and push -6. Open a PR -7. Stay with the PR until checks finish or failures are fixed - -### Branch and PR Discipline - -- Never commit directly to `main` -- Never stop at `git push` -- Opening the PR is not the end of the task -- The task includes watching CI, fixing failures, and responding to review comments - ---- - -## PR Workflow - -### Default PR Sequence - -```bash -git switch -c / - -# make changes - -npm run lint -npm test -npx tsc --noEmit -npm run build - -git add . -git commit -m "" -git push --set-upstream origin / -PR_URL=$(gh pr create --fill) -gh pr checks "$PR_URL" -``` - -### CI Check Loop: Use It Aggressively - -After opening the PR, you must keep checking GitHub checks. The default pattern in this repo should be explicit re-checks with `sleep` and `gh`. - -Any new push resets this process. After **every** push, treat prior CI state as stale, then restart the check loop from the latest commit. - -For follow-up pushes to an existing PR, the default mental model is: - -```bash -git push && sleep 300 && gh pr checks "$PR_URL" -``` - -That shorthand means "push, wait, then verify the latest PR state." Do not treat `git push` alone as completion. - -Use this pattern repeatedly: - -```bash -gh pr checks "$PR_URL" -sleep 300 && gh pr checks "$PR_URL" -sleep 300 && gh pr checks "$PR_URL" -``` - -If checks are still running, keep going. If checks fail, investigate immediately and push a fix. Do not assume someone else will watch CI later. - -Do not stop after the first green snapshot if you just pushed. A fresh push can still produce a later failure, and it can also attract new bot or human review comments after CI restarts. - -`gh pr checks "$PR_URL" --watch` is useful, but the baseline expectation is still the explicit `sleep 300 && gh pr checks "$PR_URL"` re-check pattern because it works well for long-running CI and makes the agent verify completion instead of guessing. - -If your terminal tooling launches long-running commands through an async exec session, do not fire-and-forget the `sleep 300 && gh pr checks "$PR_URL"` command. Keep the same session alive and poll it until it exits so the agent actually waits for the delayed check to finish. - -### Merge Readiness - -Do not merge until all of the following are true: - -- All required checks are green -- Any failing checks were investigated and fixed -- Review comments are answered -- Unresolved conversations are handled -- The latest pushed commit has been re-checked after CI completed - -This final re-check matters: - -```bash -sleep 300 && gh pr checks "$PR_URL" -``` - -Use it before treating the PR as merge-ready. - ---- - -## Responding to PR Reviews - -### Review Handling Rules - -For each review thread, do one of the following: - -- Apply the requested change, push it, and reply with what changed -- Or explain clearly why the suggestion is being deferred or declined - -Do not leave review threads unacknowledged. -Do not push a review fix without also doing the post-push wait-and-check cycle. - -### Suggested Review Workflow - -```bash -gh pr view --json reviews -gh pr checks "$PR_URL" -``` - -After pushing a review fix: - -```bash -git push && sleep 300 && gh pr checks "$PR_URL" -``` - -Keep the `&&` guard, or use an equivalent conditional form. Do not rewrite this as two unconditional lines. - -Then fetch review state again. A review-fix push can trigger fresh CI, fresh bot comments, or follow-up human review. - -If checks are still pending, keep repeating the sleep-and-check cycle until they finish or fail. If new review comments arrive after the push, handle them before treating the PR as done. - -### Conversation Checklist - -- Every substantive review comment has a reply -- Accepted feedback is reflected in code and tests -- Deferred feedback is explicitly justified -- CI has been re-checked after the latest push -- Review state has been fetched again after the latest push - ---- - -## Useful Paths & Entry Points - -| Purpose | Path | -| --- | --- | -| Root layout | `src/app/layout.tsx` | -| Public profile page | `src/app/[username]/page.tsx` | -| Dashboard overview page | `src/app/dashboard/page.tsx` | -| NextAuth config | `src/lib/auth.ts` | -| NextAuth route | `src/app/api/auth/[...nextauth]/route.ts` | -| Dashboard summary route | `src/app/api/dashboard/summary/route.ts` | -| Card image route | `src/app/api/card/[username]/route.ts` | -| Card renderer | `src/lib/cardRenderer.tsx` | -| GitHub summary fetchers | `src/lib/github.ts` | -| Dashboard SWR hooks | `src/hooks/useDashboardData.ts` | -| Core unit tests | `src/lib/__tests__/*.test.ts` | -| Route tests | `src/app/api/**/*.test.ts` | -| CI workflow | `.github/workflows/ci.yml` | - ---- - -## Common Tasks - -### Add a New Dashboard API Route - -1.

Keep response shape explicit and typed -5. Add a test if behavior is non-trivial - -### Change GitHub Summary Logic - -1. Update `src/lib/github.ts` or the relevant helper -2. Preserve rate-limit and not-found behavior -3. Keep authenticated GraphQL paths and unauthenticated fallbacks aligned -4. Update unit tests in `src/lib/__tests__/` - -### Change Card Rendering - -1.

it is the default way to verify CI completion before declaring the PR done -- After any push, rerun the wait-check-review cycle from scratch; previous green checks and previous review state are no longer sufficient -- In async terminal environments, waiting means keeping the spawned exec session alive and polling it to completion, not merely starting the command diff --git a/src/app/api/dashboard/stats/route.test.ts b/src/app/api/dashboard/stats/route.test.ts deleted file mode 100644 index 391f2aa..0000000 --- a/src/app/api/dashboard/stats/route.test.ts +++ /dev/null @@ -1,170 +0,0 @@ -import { describe, expect, it, vi, beforeEach } from "vitest";
