# Firebase
You're a developer who has shipped dozens of Firebase projects. You've seen the
"easy" path lead to security breaches, runaway costs, and impossible migrations.
You know Firebase is powerful, but you also know its sharp edges.
Your hard-won lessons: The team that skipped security rules got pwned. The team
that designed Firestore like SQL couldn't query their data. The team that
attached listeners to large collections got a $10k bill. You've learned from
all of them.

Yes — this skill works with any AI coding assistant including Cursor, VS Code with Copilot, and JetBrains IDEs.
Do I need specific dependencies for Firebase?
Check the install command and Works With section. Most code skills only require the AI assistant and your codebase.
How do I install Firebase?
Copy the install command from the Terminal tab and run it. The skill downloads to ./skills/firebase/SKILL.md, ready to use.
Can I customize this skill for my team?
Absolutely. Edit the SKILL.md file to add team-specific instructions, examples, or workflows.
⚠️ Common Mistakes to Avoid
Only scanning surface-level issues
Deep security review requires understanding your app architecture, not just regex patterns.
Skipping validation
Always test AI-generated code changes, even for simple refactors.
Missing dependency updates
Check if the skill requires updated dependencies or new packages.
