L1 Pre-push gate
Extended the existing pre-push hook to run every gate that CI runs. A passing local push predicts a passing CI run.
- bin/git-hooks/pre-push (extended, not replaced)
- package.json prepare script sets hooksPath on npm install
- Now covers: mdx-compile, test:agents, test:skills,
- test:manifests, token-overhead budget
L4 Token-budget warn tier
Fires a yellow WARN at 90 percent of any budget. Notice BEFORE the budget overflows, not after.
- tests/performance/test-token-overhead.sh
- check_budget_with_warn helper
- Already firing for CLAUDE.md at 95%
L7 Commit-msg linter
Blocks titles over 72 chars and banned celebratory phrases. Enforces the Tone rule in CLAUDE.md.
- bin/git-hooks/commit-msg (new, executable)
- 13 banned patterns including emoji on completion
- Soft-warns when body exceeds 50 lines
Trace — what happened when I pushed this very PR
The hook caught two real problems
$ git push -u origin feat/road-to-10-wave-1

Pre-push validation passed
$ → push accepted
Two gates caught real issues, forced me to fix them before publishing. Without this hook they would have surfaced as CI-catches on the PR — costing reviewers time and another round-trip.
Commit-msg linter — attempted and rejected
My own commit message was blocked (by my own hook)
$ git commit -m "feat(ci): ... blocks banned celebratory phrases
(\"shipped cleanly\", \"all green!\", emoji on completion)"
✗ Banned celebratory phrases in commit message:
→ "shipped cleanly"
→ "all green!"
Rewrite as a factual statement. See CLAUDE.md § Tone.
Commit blocked. Fix the above and try again.
# The hook correctly flagged MY OWN commit for quoting
# the banned strings verbatim in the documentation.
# Rewrote to refer to them in prose. Commit accepted.
