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).

# /dba — data layer
|
|
|
|
Own the data layer of **Time Machine** (see `CLAUDE.md`). Storage is **Postgres on the shared
|
|
server, its own `time_machine` database**. **No ORM, no migration framework** — the schema
|
|
self-bootstraps in `server/db.ts` `initDB()`.
|
|
|
|
## Rules
|
|
- **Additive by default.** New field → `ALTER TABLE ... ADD COLUMN IF NOT EXISTS` inside
|
|
`initDB()` (idempotent, runs every boot). Add an index if it backs a read path.
|
|
- **Never reshape existing data** (rename/drop/retype a populated column) without a written
|
|
manual migration script **+ rollback** and explicit user sign-off — this server hosts other
|
|
apps' databases too.
|
|
- **Every query `user_id`-scoped and parameterised.** No string interpolation of user input.
|
|
- **DATE stays a string.** Keep `pg.types.setTypeParser(1082, …)` in `db.ts` or timezone drift
|
|
returns.
|
|
- **Transactions** for multi-row invariants (see reorder + rollover).
|
|
|
|
## Verify safely
|
|
Use the smoke pattern from `docs/SETUP.md`: connect as admin → `CREATE DATABASE` if missing →
|
|
boot `dist/index.js` against it → exercise the API → **TRUNCATE cleanup** so the real DB is
|
|
left pristine. Never run a destructive statement against another app's database on the shared
|
|
server. Present schema diffs before applying. End with `## Next`.
|
|
|
|
## 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).
|
|
|
|
## 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.
