adk-agent-builder
Builds ADK (Agent Development Kit) Python agents: LLM agents with tools, graph workflows of function and agent nodes, conditional routing, fan-out and join, schema-validated delegation between agents, human-in-the-loop pauses, and pytest coverage for all of it. Use when asked to create an agent or a workflow, add a tool to one, branch or loop between nodes, run steps in parallel, pause for user approval, or test an agent. Don't use for explaining how ADK works internally or designing its core components (use `adk-architecture`), for an agent that already runs but misbehaves (use `adk-debug`), for authoring a sample under `contributing/` (use `adk-sample-creator`), or for naming, typing, and formatting conventions (use `adk-style`).

- Gen Agent Trust Hubpass
This skill provides a comprehensive reference and builder for the Google Agent Development Kit (ADK), enabling the creation of LLM agents with workflow orchestration and tool integration. It incorporates several security best practices, such as schema-validated delegation and human-in-the-loop controls, to manage its powerful capabilities for code execution and external service interaction.

What does this agent skill do?
ADK Agent Builder
Read only the reference that matches the task. Loading the whole tree costs context and buries the part that matters.
Every API below was checked against google-adk 2.6.2. If a symbol is missing
at runtime, read the source under src/google/adk/ rather than guessing a
neighbouring name.

Building blocks
- tool-catalog.md — function tools, MCP, OpenAPI,
Google API toolsets, built-in tools, custom
BaseToolandBaseToolset. - function-nodes.md — plain functions as nodes:
parameter resolution, generators,
node_inputtyping rules. - llm-agent-nodes.md — an
LlmAgentused as a workflow node: output types, instruction templates,output_schema, auto-wrapping behavior. - task-mode.md —
mode='task'andmode='single_turn'delegation with schema-validated input and output.
Graph orchestration
- routing-and-conditions.md — routed edges, dict routing maps, default routes, self-loops, revision loops.
- parallel-and-fanout.md — fan-out edges,
JoinNodefan-in,parallel_worker=Truelist processing. - dynamic-nodes.md — scheduling nodes at runtime
with
ctx.run_node()and imperative workflow construction. - human-in-the-loop.md —
RequestInput, resume behavior, resumable vs replayed sessions. - advanced-patterns.md — nested workflows,
retries, custom
BaseNodesubclasses, graph validation rules. - multi-agent.md — chat-transfer hierarchies, and
the deprecated
SequentialAgent/LoopAgent/ParallelAgentshells thatWorkflowreplaces.
Runtime and verification
- state-and-events.md — the
Contextobject,Eventfields, and how state flows between nodes. - session-and-state.md — session services, artifacts, memory, and state key scoping.
- callbacks-and-plugins.md — the six agent callbacks and app-level plugins.
- testing.md —
pytestwithInMemoryRunner, faking a model, asserting on node output.
