Agents CLI: ADK Code Reference
Part of Google's agents-cli skills suite. Provides a quick-reference cheatsheet for the ADK Python SDK — defining agents, tools, callbacks, state management, and multi-agent orchestration (SequentialAgent, ParallelAgent, LoopAgent, custom BaseAgent) — plus a topic-indexed catalog of reference recipes covering capabilities like sandboxed code execution, cross-session memory, approval gates, tool guardrails, per-user credentials, and scheduled or event-driven runs. Explicitly scoped to writing code, not scaffolding a project (google-agents-cli-scaffold) or deploying it (google-agents-cli-deploy).

What it does
Quick reference and reference-recipe catalog for writing agent code against Google's Agent Development Kit (ADK) Python API — agents, tools, orchestration, callbacks, and state.

What this skill does
This is an overview of the skill from the site, not the skill's real instructions. The full SKILL.md Claude reads when this skill is active lives on GitHub at the source below.
A skill from Google’s
google/agents-cli. The canonical source — including the CLI, the other 6 skills, and release notes — lives in that repo.
What this skill does
Covers the Python ADK SDK: Agent, tools, callbacks, plugins, state, artifacts, and multi-agent orchestration. It’s the reference an agent reaches for while actually writing code, after a project has been scaffolded (via google-agents-cli-scaffold) and after design has been settled (via google-agents-cli-workflow’s Phase 0).
Quick reference
from google.adk.agents import Agent
def get_weather(city: str) -> dict:
"""Get current weather for a city."""
return {"city": city, "temp": "22°C", "condition": "sunny"}
root_agent = Agent(
name="my_agent",
model="gemini-3.7-flash",
instruction="You are a helpful assistant that ...",
tools=[get_weather],
)Recipe catalog
Before implementing anything non-trivial, the skill directs you to a topic-indexed catalog of reference recipes with worked implementations 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 or event-driven runs. The philosophy is explicit: hand-writing a sandbox wrapper or a memory store for a capability the index already covers means you stopped short of using the reference.
Prerequisites for writing code
- Verify a project exists:
agents-cli info - New project:
agents-cli scaffold create <name> - Existing code:
agents-cli scaffold enhance .
Currently covers the Python ADK SDK only; support for other languages is planned.
Scope
Does not cover project scaffolding (google-agents-cli-scaffold) or deployment (google-agents-cli-deploy) — those are separate skills in the suite.
