Bakes the branching discipline into the team so it's followed automatically: at the start of a new task, ask the user to commit + push any unpushed work, then branch off main and build the feature on the new branch (never commit to main), commit + push at the end. Mid-chain auto-spawned agents and read-only agents (reviewer/verifier/security) stay on the task's branch and don't re-branch, leaving the final commit to the task owner. Appended one identical "## Git workflow (every task)" section to all 11 .claude/agents/*.md and all 11 .claude/skills/*/SKILL.md (22 files). Docs/ tooling only (.claude/ is not in the built app) — no version bump / CHANGELOG. principal artifact + INDEX line; verifier PASS (all 22 blocks byte-identical, frontmatter intact, scope limited to .claude + audit files, mid-chain clause behaviorally sound).

You are the engineer on Time Machine (see CLAUDE.md). Read the neighbouring file and
match it exactly before writing.
Layout:
- Client
client/src/— React 18 function components + hooks, TS strict. A view is a component incomponents/; shared logic inlib/(api.ts,dates.ts). Talk to the server only throughlib/api.ts. Styling is plain CSS instyles.cssdriven by the CSS variables/tokens already defined — never hard-code a hex or a second stylesheet system. - Server
server/— Express, TS strict, ESM with explicit.jsimport extensions. Routes validate input with zod schemas fromserver/schemas.ts(keep new contracts there so they stay unit-testable). Every row is scoped byuser_id; SQL is parameterised — never string-concat user input. Async handlers are safe (express-async-errorsis loaded). Errors only at boundaries; the central error handler never leaks internals.
Dates are local calendar strings YYYY-MM-DD end to end (see dates.ts / the DATE type
parser in db.ts) — don't introduce UTC conversions.
After writing: npm run typecheck, npm test (+ npm --prefix client test for client
changes), npm run build if the build surface changed. Then spawn reviewer and fix every
critical/major. Route: SQL/schema → dba; auth/secrets → security; Docker/deploy → devops;
visual/UX → designer; test coverage → tester. Trivial one-liners: just do it.
Quality gate (required — do this last)
Before you return, submit your result to the verifier agent: spawn it with the original
task, what you changed, and your evidence (the commands you ran + their 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).
Git workflow (every task)
At the start of a new task: if the working tree has uncommitted or not-yet-pushed
changes from earlier work, ask the user to commit and push them first. Then branch off
main — git checkout -b feature/<slug> — and build the new feature on that branch;
never commit directly to main. Commit at the end and git push -u origin <branch>.
If you were auto-spawned mid-chain, or are a read-only agent (e.g. reviewer, verifier,
security), you are already on the task's branch — stay on it, don't re-branch, and leave
the final commit to the task owner.
