google-agents-cli-adk-code

Quick reference for ADK Python patterns: agents, tools, callbacks, and state management.

- Covers agent creation with model and instruction configuration, basic tool definition via FunctionTool, and callback patterns for state initialization and lifecycle hooks

- Includes built-in tool imports, agent orchestration (SequentialAgent, ParallelAgent, LoopAgent), and state management through CallbackContext

- ADK 2.0 Workflow API available as opt-in experimental feature for graph-based pipelines with conditional routing and parallel processing; requires Python 3.11+ and explicit user consent before use

- Requires an existing scaffolded project; use agents-cli scaffold create or scaffold enhance before writing agent code

ADK Code Reference

Before using this skill, activate /google-agents-cli-workflow first - it contains the required development phases and scaffolding steps.

Prerequisites

- Run agents-cli info - if it shows project config, skip to the reference below

- If no project exists: run agents-cli scaffold create <name>

- If user has existing code: run agents-cli scaffold enhance .

Do NOT write agent code until a project is scaffolded.

Python only for now. This reference currently covers the Python ADK SDK.
Support for other languages is coming soon.
