Explain that linting catches issues early and gives Claude fast feedback on its own edits. + +- **Proposal-sourced hooks** (if user chose "Skills + hooks" or "Hooks only"): Consume \`hook\` entries from the Phase 3 preference queue. If Phase 2 found a formatter and the queue has no formatting hook, offer format-on-edit as a fallback. If the user chose "Neither" or "Skills only" in Phase 1, skip this bullet entirely. + + For each hook preference (from the queue or the formatter fallback): + + 1. Target file: default based on the Phase 1 CLAUDE.md choice — project → \`.claude/settings.json\` (team-shared, committed); personal → \`.claude/settings.local.json\`. Only ask if the user chose "both" in Phase 1 or the preference is ambiguous. Ask once for all hooks, not per-hook. + + 2. Pick the event and matcher from the preference: + - "after every edit" → \`PostToolUse\` with matcher \`Write|Edit\` + - "when Claude finishes" / "before I review" → \`Stop\` event (fires at the end of every turn — including read-only ones) + - "before running bash" → \`PreToolUse\` with matcher \`Bash\` + - "before committing" (literal git-commit gate) → **not a hooks.json hook.** Matchers can't filter Bash by command content, so there's no way to target only \`git commit\`. Route this to a git pre-commit hook (\`.git/hooks/pre-commit\`, husky, pre-commit framework) instead — offer to write one. If the user actually means "before I review and commit Claude's output", that's \`Stop\` — probe to disambiguate. + Probe if the preference is ambiguous. + + 3. **Load the hook reference** (once per \`/init\` run, before the first hook): invoke the Skill tool with \`skill: 'update-config'\` and args starting with \`[hooks-only]\` followed by a one-line summary of what you're building — e.g., \`[hooks-only] Constructing a PostToolUse/Write|Edit format hook for .claude/settings.json using ruff\`. This loads the hooks schema and verification flow into context. Subsequent hooks reuse it — don't re-invoke. + + 4.

Install it with \`/plugin install skill-creator@claude-plugins-official\`, then run \`/skill-creator \` to create new skills or refine any existing skill. (Always include this one.) +- Browse official plugins with \`/plugin\` — these bundle skills, agents, hooks, and MCP servers that you may find helpful.
