The description field of the SKILL.md. The agent reads only this at startup and decides from it when to load the full skill.

Install Cloud Firestore

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add firebase/agent-skills --skill firebase-firestore

This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (firebase), or copy only this skill into ~/.claude/skills. docs

/plugin marketplace add firebase/agent-skills
/plugin install <plugin>@firebase

# or only this skill:
npx skills add firebase/agent-skills --skill firebase-firestore -a claude-code

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs
