From 45c5170acb0c501a03613e0a96d6f15f450d2ee9 Mon Sep 17 00:00:00 2001 From: Abhijeet Prasad Date: Wed, 25 Mar 2026 11:04:09 -0700 Subject: [PATCH 1/2] feat(claude_agent_sdk): Instrument hooks Instrument Claude Agent SDK hook callbacks through the Braintrust integration. This changes the request-scoped tracing flow so hook callbacks running on the SDK control channel are captured alongside the existing Claude Agent task, LLM, and tool spans. The integration now starts request tracing at query time, wraps registered hook callbacks, records hook inputs and outputs as FUNCTION spans, and preserves correct parentage for tool lifecycle hooks and Stop hooks. Users now get end-to-end visibility into Claude Agent SDK hooks, including UserPromptSubmit, PreToolUse, PostToolUse, and Stop callbacks. Hook spans attach to the matching tool span when possible, otherwise to the active LLM or task context, and UserPromptSubmit traces keep the original prompt attached to the request and LLM input. Tests were updated with cassette-backed coverage for UserPromptSubmit hook tracing, tool hook tracing, hook parent/child relationships, and prompt attachment with UserPromptSubmit enabled. The Claude Agent SDK integration test suite passes against both the latest supported SDK and 0.1.10 replay environments. --- ...parent_to_matching_tool_and_final_llm.json | 1074 +++++++++++++++++ ...test_tool_hooks_create_function_spans.json | 478 ++++++++ ...mpt_submit_hook_creates_function_span.json | 303 +++++ .../claude_agent_sdk/test_claude_agent_sdk.py | 246 ++++ .../integrations/claude_agent_sdk/tracing.py | 297 ++++- 5 files changed, 2362 insertions(+), 36 deletions(-) create mode 100644 py/src/braintrust/integrations/claude_agent_sdk/cassettes/test_hook_spans_parent_to_matching_tool_and_final_llm.json create mode 100644 py/src/braintrust/integrations/claude_agent_sdk/cassettes/test_tool_hooks_create_function_spans.json create mode 100644 py/src/braintrust/integrations/claude_agent_sdk/cassettes/test_user_prompt_submit_hook_creates_function_span.json diff --git a/py/src/braintrust/integrations/claude_agent_sdk/cassettes/test_hook_spans_parent_to_matching_tool_and_final_llm.json b/py/src/braintrust/integrations/claude_agent_sdk/cassettes/test_hook_spans_parent_to_matching_tool_and_final_llm.json new file mode 100644 index 00000000..39cfde0c --- /dev/null +++ b/py/src/braintrust/integrations/claude_agent_sdk/cassettes/test_hook_spans_parent_to_matching_tool_and_final_llm.json @@ -0,0 +1,1074 @@ +{ + "cassette_name": "test_hook_spans_parent_to_matching_tool_and_final_llm", + "events": [ + { + "op": "write", + "payload": { + "kind": "json", + "value": { + "request": { + "hooks": { + "PostToolUse": [ + { + "hookCallbackIds": [ + "hook_1" + ], + "matcher": "Bash|Read" + } + ], + "PreToolUse": [ + { + "hookCallbackIds": [ + "hook_0" + ], + "matcher": "Bash|Read" + } + ], + "Stop": [ + { + "hookCallbackIds": [ + "hook_2" + ], + "matcher": null + } + ] + }, + "subtype": "initialize" + }, + "request_id": "req_1_2ccab2db", + "type": "control_request" + } + } + }, + { + "op": "read", + "payload": { + "response": { + "request_id": "req_1_2ccab2db", + "response": { + "account": { + "apiKeySource": "ANTHROPIC_API_KEY", + "apiProvider": "firstParty", + "tokenSource": "none" + }, + "agents": [], + "available_output_styles": [], + "commands": [], + "models": [] + }, + "subtype": "success" + }, + "type": "control_response" + } + }, + { + "op": "write", + "payload": { + "kind": "json", + "value": { + "message": { + "content": "Use Bash to run pwd and ls in the workspace, then use Read on trip_notes.md and summarize the current budget and hotel status.", + "role": "user" + }, + "parent_tool_use_id": null, + "session_id": "default", + "type": "user" + } + } + }, + { + "op": "read", + "payload": { + "agents": [ + "general-purpose", + "statusline-setup", + "Explore", + "Plan" + ], + "apiKeySource": "ANTHROPIC_API_KEY", + "claude_code_version": "2.1.81", + "cwd": "", + "fast_mode_state": "off", + "mcp_servers": [], + "model": "claude-haiku-4-5-20251001", + "output_style": "default", + "permissionMode": "bypassPermissions", + "plugins": [], + "session_id": "acb219b2-6f7d-4475-826f-6eb04b901373", + "skills": [ + "update-config", + "debug", + "simplify", + "batch", + "loop", + "schedule", + "claude-api" + ], + "slash_commands": [ + "update-config", + "debug", + "simplify", + "batch", + "loop", + "schedule", + "claude-api", + "compact", + "context", + "cost", + "heapdump", + "init", + "pr-comments", + "release-notes", + "review", + "security-review", + "insights" + ], + "subtype": "init", + "tools": [ + "Task", + "TaskOutput", + "Bash", + "Glob", + "Grep", + "ExitPlanMode", + "Read", + "Edit", + "Write", + "NotebookEdit", + "WebFetch", + "TodoWrite", + "WebSearch", + "TaskStop", + "AskUserQuestion", + "Skill", + "EnterPlanMode", + "EnterWorktree", + "ExitWorktree", + "CronCreate", + "CronDelete", + "CronList", + "RemoteTrigger", + "ToolSearch" + ], + "type": "system", + "uuid": "56072b97-88ab-4844-b3db-6fc497879759" + } + }, + { + "op": "read", + "payload": { + "message": { + "content": [ + { + "signature": "", + "thinking": "The user wants me to:\n1.
