What it does
Firebase is an agent skill from davila7/claude-code-templates. Firebase gives you a complete backend in minutes - auth, database, storage, functions, hosting. But the ease of setup hides real complexity. Security rules are your last line of defense, and they're often wrong. Firestore queries are limited, and you learn this after you've designed your data model. This skill covers Firebase Authentication, Firestore, Realtime Database, Cloud Functions, Cloud Storage, and Firebase Hosting. Key insight: Firebase is optimized for read-heavy, denormalized data. I
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Serverless and Database schema design. It works with Firebase and Cloud Firestore. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 4c82aba. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Firebase loads about 445 tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 147 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

Security Rules Design
Secure your data with proper rules from day one
Data Modeling for Queries
Design Firestore data structure around query patterns
Anti-Patterns
❌ No Security Rules

When should I use Firebase?
Firebase fits situations like: tasks that involve Serverless; tasks that involve Database schema design.
How do I install Firebase in Claude Code?
Run `npx skills add davila7/claude-code-templates --skill firebase -a claude-code`. Or copy the skill folder (cli-tool/components/skills/development/firebase in davila7/claude-code-templates) into .claude/skills/firebase in your project. Claude Code loads it when a task matches its description.
How do I install Firebase in Codex?

Can I use Firebase in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add davila7/claude-code-templates --skill firebase -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/firebase, .gemini/skills/firebase, .github/skills/firebase and .opencode/skills/firebase in your project.
What does Firebase need to run?
SKILL.md names no scripts, command-line tools or credentials: Firebase is instructions for the agent only.
Does Firebase access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Firebase safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Firebase use?
