agent_with_hooks
Demonstrates every middleware hook point in the SDK with realistic transformations:
| Hook | What this example does |
|---|---|
BeforeLLM / AfterLLM |
Redact email addresses and SSNs from prompts and responses |
BeforeTool / AfterTool |
Scrub PII from tool args and results |
BeforeRetrieve / AfterRetrieve |
Prefix queries with kb:; drop documents containing SSNs |
BeforeMemoryLoad / AfterMemoryLoad |
Require tenant_id in scope; wrap recalled context with a scrubbed header |
BeforeMemoryStore / AfterMemoryStore |
Scrub PII before persist; audit log after store |
Hook activity is printed to stderr with a [hooks] prefix so you can see when each hook fires without mixing into the assistant reply.
Run
From examples/:
go run ./agent_with_hooks
Default: two-run demo (store memories + prefetch retrieval + tools, then recall).
go run ./agent_with_hooks "My email is alice@example.com. What is the return policy?"
Temporal
Hooks are Go functions — they run in the process that executes activities (the worker). Register the same hook groups on both the agent starter and the worker via HookOptions() (or equivalent WithHooks calls). Group names are fingerprinted for drift detection; hook logic consistency is your responsibility.

Overview ¶
Example agent demonstrating all middleware hook points.
Run from examples/:
go run ./agent_with_hooks go run ./agent_with_hooks "My email is alice@example.com. What is the return policy?"
Hook activity is printed to stderr with a [hooks] prefix. When AGENT_RUNTIME=temporal, register the same HookOptions on both the agent starter and the worker process.
