Reviewing a PR in the Nextly monorepo

The review bar

• Verify before you trust. For every reviewer suggestion (Codex, CodeRabbit), check the claim against the actual code and, where cheap, run the relevant test. Bots are frequently right about style and frequently wrong about behavior; apply fixes for confirmed issues, and push back with evidence (file/line, test output) when a suggestion is wrong. Never apply a suggestion you cannot explain.
• Reply and resolve every thread. Each bot comment gets a reply stating what was done (fixed in , or why it is not a real issue), then the thread is marked resolved so the bot can re-verify.
• Check the PR against the repo's invariants (ARCHITECTURE.md "Key invariants" and AGENTS.md conventions): envelope shapes, NextlyError usage, Drizzle-only, token-driven admin styling in both modes, changeset presence/absence, comment style (explains code, never references tasks or conversations), no AI attribution anywhere.

Mechanical checks

• PR title: Conventional Commits; scopes are package-based plus playground|root|ci|docs|deps|release; subject starts lowercase. Fix the title rather than bypassing the check.
• Tests: the PR adds/extends tests for what it changes; no new failures against the known baseline; integration-heavy changes name which dialect legs cover them.
• Changeset: exactly one for published-code changes (all packages, patch); none for test/CI/docs-only PRs.

Recurring defect classes (look for these specifically)

• Malformed Tailwind: stray spaces before : modifiers, duplicated opacity suffixes, v4 ! placement (suffix), raw black/white instead of theme classes.
• Table invariants: pagination not reset on search/page-size change, missing getRowId, cross-page selection broken.
• Date handling: UTC vs local drift in formatting or range boundaries.
• Inputs: missing guards on user-controlled values (length, format, numeric bounds), PII in logs, missing email preheader/text variants.
• Admin visuals: light-mode-only styling, hardcoded colors, focus states missing.
• API: hand-rolled response shapes instead of response-shapes.ts helpers; bare Error in packages/nextly; status codes inlined instead of error-code mappings.

Merging

Default policy: the founder merges. Only merge yourself when the founder has explicitly authorized it for the specific PR or program, and then only with all CI checks green and every review thread resolved.
