What does this skill do, and when should you use it?
Firebase Basics is designed for projects that use Firebase products or services, especially mobile and web applications. It covers installing the Firebase agent-skill set, authenticating with the Firebase CLI, and selecting or creating an active project. Its reference directory points to Firebase concepts, CLI usage, client libraries, MCP, infrastructure as code, and security topics. The supplied material does not document test coverage, version matrices, or implementation of every Firebase product.
Checks whether npm is available; installs or updates firebase/agent-skills through npx; uses the Firebase CLI to log in, inspect the active project, add a project alias, or create a project; directs the user to references covering core concepts, CLI usage, client libraries, MCP, IaC, and security; points to other Firebase skills or the Developer Knowledge MCP search_documents tool when the references do not contain needed information.
- A mobile developer initializing Firebase tooling for a new application.
- A web developer who needs to authenticate with Firebase CLI and select an active project.
- A team with an existing Firebase project ID that needs to bind it to the CLI.
- An engineer looking for focused references on Firebase client libraries, CLI usage, MCP, IaC, or security features.
How do you install this skill?
- Do not perform login, project creation, or configuration changes before confirming the target project, account permissions, billing impact, and intended external effects.
- Using latest npx packages and remote installation introduces supply-chain and reproducibility risks; version pinning and isolated dependency review are advisable.
- The skill depends on npm, GitHub, Firebase services, and browser authentication, so mainland-China reachability and fallback paths require separate validation.
- Shell / CLI
- Network access
- Local filesystem

Install the repository’s skill collection with:
npx skills add google/skills
Select Firebase Basics during installation. The supplied material does not specify a manual installation directory.
tmp="$(mktemp -d)"
git clone --depth 1 https://github.com/google/skills.git "$tmp"
mkdir -p ~/.claude/skills
cp -R "$tmp/skills/cloud/firebase-basics" ~/.claude/skills/
rm -rf "$tmp"Generated from the source repository and skill path; it copies only this skill's folder. If the author's install steps above differ, follow those first. To scope it to one project, replace ~/.claude/skills with that project's .claude/skills.
How do you use this skill?
Once installed, send your agent any of these to trigger it:
- Help me set up Firebase CLI and an active project for this web app.
Ask a compatible Agent Skills client for a Firebase-related task, for example: “Help me set up Firebase CLI and an active project for this web app.” The documented workflow includes checking npm, installing firebase/agent-skills, logging in with Firebase CLI, and checking or configuring the active project.
What are this skill's strengths and limitations?
- Documents npm, agent-skill installation, CLI authentication, and project-selection steps.
- Includes references for Firebase concepts, client libraries, MCP, IaC, and security.
- Targets both mobile and web projects.
- The collection is Apache-2.0 licensed and can be installed with npx.
- Requires a Node.js environment with npm and npx, plus network access.
- Firebase CLI operations require an authenticated account with appropriate project permissions.
- The supplied materials show no test suite, compatibility matrix, or detailed API examples.
- This profile covers only Firebase Basics, not sibling skills in the repository.

How did FollowSkills review this skill?
The files document least-privilege IAM, Security Rules, App Check, environment separation, human approval for sensitive operations, and preservation of existing MCP servers. However, they mandate unpinned latest-version npx installs, CLI login, and potentially project creation without sufficiently explicit consent, data-flow disclosure, permission scoping, or rollback guidance, so points are deducted.
The main sequence is coherent, covering npm checks, skill installation, login, and project selection. However, latest-version remote dependencies are nondeterministic, and there are no committed tests, version pinning, robust abnormal-input handling, diagnostic failure messages, or rollback procedures; static evidence supports only a modest score.
The scope clearly targets mobile and web projects using Firebase and covers CLI, SDK, IaC, and security topics. Trigger semantics are broad, with no clear non-fit boundaries or input/output contract, no Chinese-language support evidence, and core reliance on npm, GitHub, Firebase services, and browser login may create mainland-China reachability issues.
The documentation has metadata, a quick-start section, layered references, examples, and security caveats. Repository context supplies Apache-2.0 licensing, official Google provenance, a pinned revision, and an issue-based feedback path. The skill itself lacks a version, changelog, explicit maintenance owner, and concrete update process, and some listed external references are not included in the supplied skill files.
The skill provides usable setup guidance for Firebase projects and highlights security rules and access control. However, substantive implementation is delegated to an additional firebase/agent-skills installation or external documentation; mandatory setup adds cost and can cause external state changes, while output completeness and comparative benefit are not statically verified, so the score remains below the execution-capable anchor.
Evidence consists of the revision-pinned skill files, structured reference material, command examples, repository license, and maintenance entry points. There is no committed test suite, CI coverage, third-party execution record, or independently reproducible result evidence; this is a static review only, so the score stays below5.
