 This repo hosts ThemeGrill's shared bot automation: reusable GitHub Actions workflows (PR build-zip, Copilot review) and the Crisp → AI → GitHub issue triage pipeline. Machine user: `tg-autopilot`.
 
-**Before doing anything here, check `.claude/skills/` first.** There is very likely already a skill covering the task — onboarding a repo, debugging a specific failure mode, verifying a change actually took effect. Re-deriving one of these from scratch instead of using the existing skill is exactly how repeat mistakes happen; see `CHANGELOG.md` 2026-09-29 for one that cost real debugging time.

 ## Map
 
 - `SETUP.md` — Phase 1 (pr-build-zip, Copilot review): one-time credentials/setup.
 - `PHASE2-SETUP.md` — Phase 2 (Crisp triage): credentials/setup **and** the actual design policy — § 4c/4d explain what triggers an investigation and why, and are the first thing to read before touching `crisp-classify.mjs`.
 - `CHANGELOG.md` — dated entries for notable fixes/redesigns. Read the most recent entries before assuming you understand current behavior; policy here has changed more than once.
-- `.claude/skills/` — task- and symptom-oriented playbooks (onboarding, debugging, verification). Check this before improvising.
+- `skills/` — task- and symptom-oriented playbooks (onboarding, debugging, verification). Check this before improvising.
 - `scripts/` — all Node scripts, most with dense "why" comments at the point of the actual gotcha, not just a docstring at the top. Read the comment before changing the line it's attached to.
 - `state/` — committed JSON state (`cursor.json`, `escalated.json`, `resolved-seen.json`, `investigated.json`, `active-notified.json`). These are data, not config — don't hand-edit without understanding what reads them first.
 - `config/inbox-to-repo.json` — Crisp account → GitHub repo routing.
