google-agents-cli-adk-code
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management", or needs ADK (Agent Development Kit) Python API patterns and code examples. Part of the Google ADK skills suite. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).

What this skill does
ADK Code Reference Activate /google-agents-cli-workflow first for required development phases and scaffolding steps. 1. Study Recipes (No Project Needed) Read the topic index in references/samples.md before answering "how do I build X". Worked implementations exist for: sandboxed/per-user code execution, agent-loadable SKILL.md skills, cross-session memory, approval gates before risky actions, tool guardrails, per-user credentials, and scheduled/event-driven runs. The index only gives you a name; the recipe is the code. Clone it and read its AGENTS.md before you implement anything it covers. Hand-writing a Docker or E2B sandbox wrapper, a skill loader, a moderation callback or a memory store — for a capability the index lists — means you stopped at the name. 2. Prerequisites for Writing Code Do NOT write agent code until a project is scaffolded. 1. Verify project: run agents-cli info (proceed if config exists). 2. New project: run agents-cli scaffold create <name>. 3. Existing code: run agents-cli scaffold enhance .. Language Support: This reference covers the Python ADK SDK. Support for other languages coming soon. Quick Reference — Most Common Patterns --- References Use cheatsheets for common patterns. For deep knowledge, fetch the docs index or inspect the installed package. Reference When to read ------ ------------- references/samples.md Topic-indexed catalog of ADK reference recipes. Read in workflow Phase 1 — before scaffolding and before writing code — maps a capability to the recipe that implements it. references/adk-python.md Core ADK API: Agent, tools, callbacks, plugins, state, artifacts, multi-agent systems, SequentialAgent / ParallelAgent / LoopAgent, custom BaseAgent, ManagedAgent (server-hosted first-party agents), A2A protocol, A2UI. Default for most agents. references/adk-workflows.md Graph-based Workflow API (ADK 2.0): nodes, edges, fan-out/fan-in, HITL, parallel processing. Use when you need explicit graph topology. …
