# /engineer — implementation
|
||
|
|
|
||
|
|
Write client or server code for **Time Machine** (see `CLAUDE.md`). Read the neighbouring file
|
||
|
|
and match it before typing.
|
||
|
|
|
||
|
|
## Map
|
||
|
|
- **Client** `client/src/` — React 18 function components + hooks, TS strict. Views live in
|
||
|
|
`components/`; shared logic in `lib/` (`api.ts` = the only path to the server, `dates.ts` =
|
||
|
|
local `YYYY-MM-DD` math). Styling = plain CSS via the tokens in `styles.css` (`--ink`,
|
||
|
|
`--surface`, `--accent`, `--work`, `--home`, radii, shadows) — no hard-coded hex, no second
|
||
|
|
styling system. Optimistic updates must roll back on error.
|
||
|
|
- **Server** `server/` — Express, TS strict, ESM with explicit `.js` import extensions. Validate
|
||
|
|
every request with a **zod** schema from `server/schemas.ts` (add new contracts there so
|
||
|
|
they're unit-testable). Every query is **`user_id`-scoped and parameterised**. Async handlers
|
||
|
|
are safe (`express-async-errors` loaded); errors only at boundaries; never leak internals.
|
||
|
|
- **Dates** are local calendar strings end to end — don't add UTC conversions (`db.ts` keeps
|
||
|
|
the DATE type a raw string on purpose).
|
||
|
|
|
||
|
|
## Definition of done
|
||
|
|
1. `npm run typecheck` clean.
|
||
|
|
2. `npm test` (+ `npm --prefix client test` for client work) green.
|
||
|
|
3. `npm run build` if you touched the build surface.
|
||
|
|
4. Spawn `/reviewer`; fix every critical/major.
|
||
|
|
5. Route specialised surfaces: SQL → `/dba`, auth/secrets → `/security`, Docker/deploy →
|
||
|
|
`/devops`, visual → `/designer`, coverage → `/tester`.
|
||
|
|
|
||
|
|
## Autonomy
|
||
|
|
Trivial one-liner → just do it. Non-trivial → short plan, one check-in, execute, show result.
|
||
|
|
|
||
|
|
## Quality gate (required — do this last)
|
||
|
|
Before returning your result, submit it to **`/verifier`**: the original task, what you changed,
|
||
|
|
and your evidence (commands run + output). If it returns `VERDICT: REDO`, fix every listed gap and
|
||
|
|
resubmit; only return once it returns `VERDICT: PASS`. There is no round cap — keep looping until PASS (the bar is *perfect for the task*); if the same gap persists across rounds with no progress, pull in `/principal` to change approach, then keep going until PASS. Never skip this (`/verifier` itself is exempt, to avoid recursion).
