What it does

Firebase Basics is an agent skill from davila7/claude-code-templates. Sets up and develops projects using Firebase products and services, especially for mobile or web apps. Covers Firebase CLI setup, project configuration, and integration with Firebase platform services.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/additional-skills.md`, `references/cli-usage.md` and `references/client-library-usage.md`).

It works with Firebase. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

Example prompts

  • “/firebase-basics”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Leverage the planning phase
  2. Ensure NPM is installed.
  3. Verify and install Agent Skills for Firebase

What it can do on your machine

Read from SKILL.md and the folder at commit 14680ec. 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

    Links to these hosts (documentation or services it may open):

    • nodejs.org

    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 Basics loads about 850 tokens when it runs, and up to ~6.7k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 397 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~850
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.7k

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 Basics

CRITICAL Mandatory prerequisites

Before attempting to fulfill any user request regarding Firebase, you MUST follow these steps in order. Do not proceed to implementation until these are completed. Failure to follow these instructions may result in using outdated patterns and lack of access to essential reference materials.

  1. Leverage the planning phase

    If you use a planning mode (e.g., maintaining a task.md file), you MUST include a task to check and install firebase/agent-skills as your very first item.

  2. Ensure NPM is installed.

    bash
    ## Check if NPM is installed
npm --version

    If NPM is not installed, guide the user to download and install the LTS version from https://nodejs.org/en/download.

    Then, request the user to manually install Node.js and to reply with a confirmation that the installation is finished. Stop and wait for the user's confirmation.

  3. Verify and install Agent Skills for Firebase

    You MUST ensure the full set of skills is installed to avoid using outdated patterns. Run this command:

    bash
    npx -y skills add firebase/agent-skills -y

    If the skills are already installed, this command will ensure they are up to date. Do not skip this step.

Quick start

After completing the mandatory prerequisites above, proceed with these steps to set up your environment:

  1. Log in to the Firebase CLI.

    Run this command:

    bash
    npx -y firebase-tools@latest login

    Then, ask the user to complete the login flow in the browser.

  2. Set an active project for the CLI.

    Most Firebase tasks require an active project context. Check the current project for the Firebase CLI by running this command:

    bash
    npx -y firebase-tools@latest use

    • If the command outputs Active Project: <PROJECT_ID>, you can proceed with your task.

    • If the command does not output an active project, ask the user if they have an existing Firebase project ID.

      • If yes: Set the ID as the active project and add a default alias by running:

        bash
        npx -y firebase-tools@latest use --add <PROJECT_ID>

      • If no: Create a new Firebase project by running:

        bash
        npx -y firebase-tools@latest projects:create <PROJECT_ID> --display-name <DISPLAY_NAME>

Reference directory

If you need product information that's not found in these references, check the other skills for Firebase that you have installed, or use the search_documents tool of the Developer Knowledge MCP server.
