Road to 10 — Wave 1 (session quality gates)

Pre-push catches what I would have pushed broken

Lever 1 + 4 + 7 from the dimension plan

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.
