# Change discipline

The canonical text is **`AGENTS.md` → "Working agreement", "Validation scope",
"Change discipline", and "Definition of Done"**. This file mirrors those rules
for Cursor; keep it in sync. If the guides disagree, AGENTS.md wins.

The short form:

1. **Complete authorized work through validation and self-review.** Resolve routine
   choices from the code; ask about missing information that changes scope or behavior.
   Plans, audits, and reviews stay read-only unless edits are requested.
2. **For user-facing features, write 3–5 acceptance criteria and explicit exclusions
   before implementation.** Put them in the PR description before the first commit;
   draft the description locally if there is no PR yet.
3. **Put a shared rule where every path reaches it, then delete the other copy** —
   not at the site the report happened to mention.
4. **Search for sibling paths**, including live/cache and statusline/hook readers.
5. **Make a new regression test fail before trusting it.** For call-site bugs,
   remove the call and confirm red; restore it afterward and preserve unrelated edits.
6. **Never assert wall-clock time.** Assert the observable consequence instead.
7. **Use AGENTS.md's validation scope and read the output.** Prose-only edits need
   `git diff --check`, link/contract checks, and the `node --input-type=module` block in
   [AGENTS.md's private-document boundary check](../../AGENTS.md#private-document-boundary-check).
   Code, dependency, and executable config
   changes need build → typecheck → test → lint plus relevant CI smoke/pack checks.
   `scripts/gate.sh` runs that list locally with one verdict per step (not `release:qa`,
   not CI's Node 22 floor, Windows and macOS jobs, which `scripts/push-and-watch.sh` reads on the
   pushed SHA); with `--commit <message-file>` it commits only when every step is ok, or, with
   `--allow-offline-audit`, when the audit alone was skipped offline (the commit line says so
   and the exit stays nonzero).
   The `verify-claudinho` skill and `node scripts/verify.mjs` are the offline inner loop; the control
   CLI replaces neither CI's jobs nor the live pass, `release:qa`.
   User-facing behavior and releases also need `release:qa` after build. Rerun checks
   for new changes, failures, or unresolved concerns; after a push, verify CI on that SHA.
8. **Start every task at the router skill**, `.claude/skills/claudinho-mode/SKILL.md`
   (mirrored at `.cursor/skills/claudinho-mode/SKILL.md`), which names the playbook for the
   task's kind, and find a failure class and the enforcer that refuses it in
   **`AGENTS.md` → "Rules and their enforcers"**.
