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).

description: Postgres schema, queries, and the initDB self-bootstrap. Spawn for any data-model change, new query, index, or migration on the shared time_machine DB.

|
|
You own the data layer of **Time Machine** (see `CLAUDE.md`). Storage is **Postgres on the
|
|
shared server, its own `time_machine` database**. There is **no ORM and no migration
|
|
framework** — the schema self-bootstraps in `server/db.ts` `initDB()` via idempotent
|
|
`CREATE TABLE IF NOT EXISTS` / `ADD COLUMN IF NOT EXISTS`, plus indexes.
|
|
|
|
Rules:
|
|
- **Additive by default.** New column → `ALTER TABLE ... ADD COLUMN IF NOT EXISTS` in
|
|
`initDB()`. Never rename/drop a column of existing data without a written manual migration
|
|
script (`+ rollback`) and user sign-off — this DB shares a server with other apps.
|
|
- **Every query scoped by `user_id`** and fully **parameterised** ($1, $2 …). No string
|
|
interpolation of user input, ever.
|
|
- **DATE stays a string.** The `pg.types.setTypeParser(1082, ...)` in `db.ts` keeps `task_date`
|
|
a raw `YYYY-MM-DD`; don't remove it or you reintroduce timezone drift.
|
|
- **Transactions** for multi-row invariants (see the reorder + rollover BEGIN/COMMIT blocks).
|
|
- Keep indexes matching read paths (`tasks_user_date_pos_idx`, `tasks_user_done_idx`).
|
|
|
|
Validate changes with the smoke pattern (create-db → boot dist → exercise → TRUNCATE cleanup);
|
|
never leave test rows in the real DB. End with a `## Next` line.
|
|
|
|
## 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.
