firebase-remote-config-basics covers Firebase Remote Config, which changes app behavior and appearance without an app update. The agent downloads the template to remote_config.json, edits conditions and parameters, and stops for your review before anything is deployed.

The SKILL.md says to tell you to review the file and wait until you say deploy. It then maps the local file in firebase.json, runs a partial deploy of the remoteconfig service, and lists the version history to verify.

SDK guides cover Android and iOS: in-app defaults, fetch and activate, and a real-time listener. The recommended loading pattern is to activate old values at startup and fetch new ones for next time.

Good for

Mobile developers using feature flags and remote values
Teams editing Remote Config templates and conditions from the command line
Developers setting in-app defaults and fetch strategies

Install firebase-remote-config-basics

Claude Code

Copy this prompt.

Install the firebase-remote-config-basics skill in Claude Code. Run this command:

claude plugin install firebase@firebase

Then check that it loaded and tell me how to use it.

Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js 20+, Google account.

The plugin route is the one the Firebase skills recommend for Claude Code. It installs all 13 skills in the repo and a Firebase MCP server, which .mcp.json starts with npx -y firebase-tools@15.32.1 mcp --dir . (version at review time). Restart Claude Code afterwards. The skills CLI route installs only the skills named. Every route needs Node.js 20 or newer, and the skills run the Firebase CLI through npx, so you also sign in to Firebase with a Google account. The README writes the marketplace as firebase/skills; the repository is firebase/agent-skills, the name the vendor Claude Code setup guide uses.

What it includes

remoteconfig:get -o remote_config.json
Saves the remote template to a local file for auditing or editing.
Runs code · Get the template
Change conditions and parameters in the JSON
The agent picks a signal, such as device.country or percent, and updates the conditions array and parameters map.
Edit locally
Stops and asks you to say deploy
The SKILL.md makes user review mandatory: the agent tells you the changes are in remote_config.json and waits.
Review gate
deploy --only remoteconfig; remoteconfig:versions:list
If firebase.json is missing, it creates one mapping the template to remote_config.json. After deploy it lists version history.
Runs code · Deploy and verify
Activate at startup, fetch for next time, or real-time
Activate previously fetched values immediately, fetch in the background, or use the real-time listener for instant updates.
Loading strategies
npx 403 errors and missing project
On a registry 403 it tells you and may fall back to a global firebase command if you confirm. With no active project it asks for the ID and adds --project to every command.
Troubleshooting
Android and iOS: defaults, fetch and activate
Two reference guides for Android (Kotlin) and iOS.

Watch out for

Deploy changes what your live app does
deploy --only remoteconfig pushes the template to your project. The skill waits for your go-ahead, so review conditions and percentages first. github.com
It runs the latest Firebase CLI through npx
Commands use npx -y firebase-tools@latest, which downloads and runs the newest published package each time. You sign in to Firebase with your Google account. github.com
The plugin route adds a Firebase MCP server
The Firebase plugin ships an .mcp.json that starts `npx -y firebase-tools@15.32.1 mcp --dir .` with IS_FIREBASE_MCP=true, so a Firebase MCP server runs in your project folder. The pinned version was 15.32.1 at review time. The skills CLI route does not add it. github.com

Questions

What does firebase-remote-config-basics do?

It guides your agent to manage Firebase Remote Config: edit the template and conditions from the CLI, deploy after your review, and use the SDK on Android and iOS.

How do I install it in Claude Code?

Use the install box above. The plugin route installs every Firebase skill and the MCP server. The skills CLI route installs this skill and firebase-basics, which it points to for project setup.

Will it deploy changes without asking?

No. The SKILL.md makes a user review mandatory: the agent says the changes are in remote_config.json and waits for you to say deploy.

Does it support web or Flutter?

Its SDK guides cover Android and iOS.

Does it need an API key?

No API key is named in the SKILL.md. The Firebase CLI signs in with your Google account (npx -y firebase-tools@latest login), and most tasks need an active Firebase project.

Is firebase-remote-config-basics safe to use?

A Remote Config deploy changes values your live app reads. The skill pauses for your review first, so read the diff of remote_config.json and confirm the project before saying deploy.
