Claude Code SDK hooks do not work #193
Description
Hello,
I am trying to use hooks from the claude code sdk from the docs here, but am not seeing hooks getting called. I have a simple repro here:
from claude_agent_sdk import query, ClaudeAgentOptions, HookMatcher, HookContext
from typing import Any
import asyncio
# Track hook calls
hook_calls = []
async def log_hook(
input_data: dict[str, Any],
tool_use_id: str | None,
context: HookContext
) -> dict[str, Any]:
"""Log all tool usage for auditing."""
print(f"HOOK CALLED: {input_data}")
return {}
async def main():
options = ClaudeAgentOptions(
hooks={
'PreToolUse': [
HookMatcher(hooks=[log_hook])
],
'Stop': [
HookMatcher(hooks=[log_hook])
]
},
max_turns=3 # Limit turns to speed up test
)
message_count = 0
async for message in query(
prompt="List all files in ths directory.",
options=options
):
message_count += 1
print(f"Message {message_count}: {type(message).__name__}")
print(f"\nTotal hook calls: {len(hook_calls)}")
print(f"Hook calls: {hook_calls}")
if not hook_calls:
print("\nERROR: No hooks were called!")
else:
print("\nSUCCESS: Hooks were called!")
if __name__ == "__main__":
asyncio.run(main())
I'm on the latest version of the SDK claude-agent-sdk==0.1.0. Am I missing something obvious? Thanks!
