Google-ADK-Skills

25 production-grade Google ADK skills for Codex, OpenCode, Claude, Cline, Cursor, Gemini CLI, and Windsurf

Build sophisticated AI agents using Google's Agent Development Kit (ADK): multi-agent orchestration, LangGraph state machines, LiteLLM multi-provider routing, real-time bidirectional streaming, RAG pipelines, MCP tool integration, autonomous agents, and production deployment.

Installation

Option 1 — Skills CLI (canonical)

npx skills add OMIXEC/Google-ADK-Skills

The skills.sh CLI is the primary install path for agent skills. It installs the GitHub skill collection and makes the repo visible on skills.sh after the repository has been seen by the CLI.

Option 2 — Repo installer (custom targets and advanced options)

# Auto-detect installed tools/config dirs and install all skills
curl -fsSL https://raw.githubusercontent.com/OMIXEC/Google-ADK-Skills/main/install.sh | bash

# Guided install with target/method/runtime/skill prompts
git clone https://github.com/OMIXEC/Google-ADK-Skills.git
cd Google-ADK-Skills
bash install.sh --interactive

By default the installer only installs skill folders. It does not require Python, pip, Google credentials, GitHub auth, or shell rc changes.

Main target paths:

Target	Skills directory
codex	~/.codex/skills
opencode	~/.opencode/skills
claude	~/.claude/skills
cline	~/.cline/skills
cursor	~/.cursor/skills
gemini-cli	~/.gemini/skills
windsurf	~/.windsurf/skills

Flags:

--target <codex|opencode|claude|cline|cursor|gemini-cli|windsurf|all|auto>
--copy                 Copy skill folders instead of symlinking them
--install-dir <path>   Checkout/cache location, default: ~/.google-adk-skills
--skills-dir <path>    Install into a custom tool skills directory
--scope <user|global>  User home install or global /usr/local/share install
--ref <branch-or-tag>  Git ref to install, default: main
--skills <list|all>    Comma-separated skills to install, default: all
--interactive          Prompt for target, method, runtime, evals, and skills
--with-evals           Keep tests/ in the install checkout
--with-runtime         Create a Python venv and install runtime dependencies
--shell-integration    Add the adk alias/PATH entry to your shell rc file
--force                Replace existing non-symlink skill directories

Examples:

# Install for Codex and replace any existing copied skills
bash install.sh --target codex --copy --force

# Install into the main skills paths for every supported tool
bash install.sh --target all

# Install globally for every supported tool (requires writable /usr/local/share)
sudo bash install.sh --target all --scope global

# Install only selected skills
bash install.sh --target opencode --skills adk-agents,adk-tools,adk-memory

# Install into any compatible custom skills directory
bash install.sh --skills-dir ~/.my-agent-tool/skills --copy

# Install skills plus the Python runtime helpers
bash install.sh --target claude --with-runtime --shell-integration

Option 3 — package shim

npx google-adk-skills
npx google-adk-skills --interactive
npx google-adk-skills --target cline --copy

The npx package is a thin wrapper around install.sh and passes all flags through to the same installer. The legacy npx claude-adk-skills binary remains as a compatibility alias.

Option 4 — Claude Plugin Marketplace (experimental)

/plugin marketplace add OMIXEC/Google-ADK-Skills
/plugin install google-adk-skills

Use npx skills add OMIXEC/Google-ADK-Skills as the reliable public path today. The repo installer remains available for custom target paths, selective installs, runtime helpers, and global installs.

Prerequisites

• Skills-only install: bash plus either git, curl, or wget.
• Runtime helpers: Python 3.11+ and pip, enabled with --with-runtime.
• ADK usage after install: GOOGLE_API_KEY or the credentials required by the models/tools you choose.
• Optional: PINECONE_API_KEY for RAG and LITELLM_* keys for multi-provider routing.
