review

Review all files you changed in this session. Focus on patterns specific to this codebase. This is a cross-cutting review — it also touches on backwards compatibility and types/api.ts regeneration, which are commonly-forgotten 100cims specifics.

What to flag

1. Bad TypeScript patterns

• as any / as SomeType (except as const) — prefer type guards, satisfies, or generics.
• Non-null assertions (! postfix, e.g. x!.foo, map.get(k)!) — prefer explicit null checks, ??, or optional chaining.
• @ts-ignore / @ts-expect-error without a -- reason comment.
• console.log left in committed code.
• Hardcoded values that belong in a constant / env var.
• Re-exports of symbols the file doesn't define. export { X } from "./other" and export type { X } from "./other" are both violations unless the file is explicitly a package's public-API barrel (e.g. components/ui/atoms/index.ts). Callsites import X from where X lives — re-exporting "alongside related hooks for convenience" still drifts, fragments ownership, and pads the bundle. The global rule lives in ~/.claude/CLAUDE.md "Critical Rules"; this skill's job is to catch its violations.

2. Manually edited generated types

If packages/app/types/api.ts is in the diff, flag it. This file is regenerated by yarn app generate-api-types against the running API's Swagger — never hand-edit.

3. Mobile app (packages/app)

• User-facing strings not wrapped in useIntl / translation keys.
• Direct fetch / apiClient calls from components — should go through react-query hooks in domains/<entity>/*.api.ts.
• Missing loading / error states on screens that fetch data.
• Inline styles instead of NativeWind classes.
• Env vars without the EXPO_PUBLIC_ prefix (those don't reach the client).
• Translations not extracted + filled in. Adding <FormattedMessage defaultMessage="..."> or intl.formatMessage({ defaultMessage: "..." }) is only step 1 — you MUST also:
  1. Run yarn workspace @100cims/app translations (extracts new keys into translations/raw-en.json and compiles translations/en.json).
  2. Add the new keys to both packages/app/translations/ca.json (Catalan) and packages/app/translations/es.json (Spanish), inserted in alphabetical order by key hash.
  3. Verify with grep that all three locale files contain the new key(s). Never ship English-only strings — the app runs in Catalan/Spanish for most users.

4. API (packages/api)

• Missing TypeBox schema validation on route bodies / queries / params / responses.
• Routes under public/ or protected/ that should be admin-only (or vice-versa).
• Missing onError logging hook coverage for new error paths.
• New DB query patterns that would be slow without an index — flag for review.
• S3 upload endpoints without image size / MIME validation.
• Multiple Elysia endpoints bundled into one file — one file = one endpoint (see AGENTS.md).
• Routes added but not mounted in the parent index.ts composer.
• Hand-authored migration files under packages/api/src/db/drizzle/ or hand-edited drizzle/meta/_journal.json — flag either. Migration files must be produced by drizzle-kit: yarn api db:generate for schema changes, yarn api db:generate --custom --name <slug> for pure data changes (backfills, renames, merges). See AGENTS.md for the full flow.
• CRITICAL — custom migration SQL must use snake_case column identifiers, NOT camelCase. Drizzle's text()/boolean()/uuid() builders map TS field imageUrl to DB column image_url; quoting "imageUrl" in raw SQL references a column that doesn't exist. drizzle-kit swallows the PG error and just prints exit code: 1, which silently breaks every Railway build until the migration is fixed. For every new *.sql file under packages/api/src/db/drizzle/, scan each INSERT (...), UPDATE ... SET, and WHERE clause and confirm every identifier matches a real column (cross-check against an existing migration like 0001_seed-data.sql or against information_schema.columns).

5. API backwards compatibility (CRITICAL)

Mobile app versions in the wild cannot be updated reliably — users may be on months-old versions. Every API change MUST be backwards-compatible:

• Never remove fields from response schemas — old clients depend on them.
• Never rename fields — add a new one alongside the old.
• Never change field types — a string stays a string.
• Never remove endpoints — deprecate instead.
• New required body fields must have sane defaults or be optional.
• Body field renames must accept both old and new names simultaneously.

Flag any diff that violates the above. If a response shape genuinely needs to shrink, call it out and ask the user.

6. Skill drift

Scan .claude/skills/ (both project-local and ~/.claude/skills/) for skills that are adjacent to the work you did. If your change introduced a new pattern, utility, or gotcha that a future agent should know, update the relevant skill. Do NOT update skills speculatively — only when a concrete, reusable fact emerged from this session.

How to review

1. git diff --name-only HEAD (or compare to main) to list changed files. Group by package.
2. For each file, read it and scan for the categories above relevant to that file's area.
3. Report findings grouped by file with line numbers and exact suggestions.
4. After reporting, fix anything mechanical (typos, missing validation, console.log, obvious backwards-compat issues). Leave preference-driven suggestions as a list for the user.

Verification (always run at the end)

After reviewing + fixing, run lint and type-check for any package you touched:

# If packages/app/ changed
yarn app lint
./node_modules/.bin/tsc --noEmit -p packages/app/tsconfig.json

# If packages/api/ changed
yarn api lint
./packages/api/node_modules/.bin/tsc --noEmit -p packages/api/tsconfig.json

If errors exist in files you modified, fix them before reporting done. If errors exist in files you did NOT touch, list them as "pre-existing" and move on.

Regenerate types if API surface changed

If you added / changed / removed an Elysia route or its schema, regenerate the mobile-side OpenAPI types:

yarn app generate-api-types

This requires the API dev server running (yarn api dev). Commit the resulting packages/app/types/api.ts change with the same PR as the route change.

Output

End with one of:

• No issues found. Lint + type-check pass.
• A short list of issues, what you fixed, and what still needs the user's judgement.
