Gemini CLI skills, plugins and MCP servers
Everything that installs into Gemini CLI: skills, subagents, commands, rules and MCP servers. Each card has an install command and example prompts.
Nothing here yet: cards appear once a checked description is ready.
Gemini CLI is the Google terminal agent. Its own docs say that on June 18, 2026 it was replaced by Antigravity CLI for the unpaid tier and Google One users, so check which tool your account actually gets before you invest in it.
Project context comes from GEMINI.md, with @file.md imports up to five levels deep. To read AGENTS.md, add it to context.fileName. Skills live in .gemini/skills/ or .agents/skills/ and install with gemini skills install. Commands are TOML files in .gemini/commands/, subagents are Markdown in .gemini/agents/, and hooks and MCP servers go in settings.json. One MCP quirk: url means SSE, while streamable HTTP uses httpUrl. Extensions are built around gemini-extension.json.
