Agent implementations (LLM, Custom, Workflow agents).
Provides the core agent types:
LlmAgent- AI-powered agent using LLMsCustomAgent- Implement custom agent logicSequentialAgent- Execute agents in sequenceParallelAgent- Execute agents concurrentlyLoopAgent- Iterative execution until condition met
Available with feature: agents
Modules§
- compaction

- LlmConditional
Agent Builder - Builder for constructing an
LlmConditionalAgent. - LlmEvent
Summarizer - An LLM-based event summarizer for sliding window compaction.
- Loop
Agent - Loop agent executes sub-agents repeatedly for N iterations or until escalation
- Parallel
Agent - Parallel agent executes sub-agents concurrently
- Sequential
Agent - Sequential agent executes sub-agents once in order
Constants§
- DEFAULT_
LOOP_ MAX_ ITERATIONS - Default maximum iterations for LoopAgent when none is specified. Prevents infinite loops from consuming unbounded resources.
- DEFAULT_
MAX_ ITERATIONS - Default maximum number of LLM round-trips (iterations) before the agent stops.
- DEFAULT_
TOOL_ TIMEOUT - Default tool execution timeout (5 minutes).
Traits§
- Agent
- The fundamental trait for all ADK agents.
Functions§
- normalize_
content - Normalize content by converting tool call markup in text parts to FunctionCall parts.
- normalize_
option_ content - Normalize
Option<Content>by converting tool call markup.
Type Aliases§
- After
Tool Callback Full - Rich after-tool callback that receives the tool, arguments, and response.
- OnTool
Error Callback - Callback invoked when a tool execution fails (after retries are exhausted).
