This skill should be used when troubleshooting Firebase emulator issues, rules violations, function errors, auth problems, or deployment failures. Triggers on "error", "not working", "debug", "troubleshoot", "failing", "broken", "permission denied", "emulator issue".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Firebase Debugging ## Overview This sub-skill guides systematic troubleshooting of Firebase development issues. It handles emulator problems, rules violations, function errors, auth issues, and deployment failures. **Key principles:** - Identify issue type first (emulator, rules, functions, auth, deployment) - Use Emulator UI and Rules Playground for diagnosis - Export emulator state before restarting - Document issues and solutions for future reference ## When This Sub-Skill Applies - Emulators won't start or have port conflicts - Getting Firestore rules violations (PERMISSION_DENIED) - Cloud Functions returning errors or not executing - Authentication not working in emulators - Deployment fails with cryptic errors - User says: "debug", "troubleshoot", "error", "not working", "failing" **Do not use for:** - Setting up new projects → `firebase-development:project-setup` - Adding new features → `firebase-development:add-feature` - Code review without specific errors → `firebase-development:validate` ## TodoWrite Workflow Create checklist with these 10 steps: ### Step 1: Identify Issue Type Categorize the error: | Category | Symptoms | Keywords | …

How to install
mdr add aiskillstore/marketplace/firebase-development-debug@sha256:5de0347264d5743dThe line at the top of this page pins the label git:20260113.222b7de, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
