What problem does it solve? Claude Code configuration files (CLAUDE.md, rules, skills, commands, agents, settings.json) drift out of spec as Anthropic ships new frontmatter fields and deprecates old ones, causing silent failures like rules that never load or token budgets that blow up. This Skill acts as a spec gatekeeper so every config change follows the 2026 April rules and avoids known bugs. ## Core Features & Use Cases - 7-step audit playbook: Identify file type, read the matching spec reference, apply token budgets, validate frontmatter, check known bugs (#23478, #21858, #16299, #16853), write, and verify. - Automated compliance scanning: Run scripts/audit-config.js to check CLAUDE.md line counts, rules paths frontmatter, SKILL.md naming, settings.json deprecated env vars, and hook file integrity. - PostToolUse guard hook: cc-config-guard.js injects spec reminders whenever any .claude/ file is written, working around Bug #23478 where paths rules do not load on Write. - Use Case: You want to add a new rule that only applies to TypeScript API files. The Skill tells you to use paths frontmatter, warns that Write-triggered creation will not load it (Bug #23478), and provides a hook fallback plus a copy-ready template. ## Quick Start Ask the AI to audit your .claude directory for 2026 spec compliance using the cc-config-author skill.
