agentdelta: Command for Claude Code

Scaffold a new instrumentation adapter for a framework not yet supported by agentdelta.

Usage: /project:add-adapter <framework_name>

Framework name from $ARGUMENTS (e.g. "autogen", "crewai", "smolagents", "pydantic-ai").

Generate the following:

1. src/agentdelta/instrument_<framework>.py — adapter module:

   • A class <Framework>AgentdeltaAdapter that wraps the framework's event/callback API
   • Must emit TraceNode objects to an AgentTrace for each: agent start, LLM call, tool call, tool return, agent end
   • Use NodeType.START, NodeType.LLM, NodeType.TOOL_CALL, NodeType.TOOL_RETURN, NodeType.END
   • Include a record_<framework>() context manager mirroring the LangChain record() API

2. Export from src/agentdelta/__init__.py:

   • Add to __all__ alphabetically

3. tests/test_instrument_<framework>.py — at least 3 tests:

   • Callback captures LLM output as a NodeType.LLM node
   • Callback captures tool calls as NodeType.TOOL_CALL nodes
   • record() context manager saves a valid JSONL file on exit

4. Update README.md Quick Start section with a snippet for the new framework

5. Update pyproject.toml optional dependencies:

   • Add [<framework>] extra with the framework package pinned to >= minimum supported version

Context:

• See src/agentdelta/instrument.py for the LangChain reference implementation
• AgentTrace.add_node() and add_edge() are the only write methods needed
• Keep content fields under 2000 chars for LLM nodes, 500 chars for tool nodes
• The adapter does NOT need to import agentdelta internals other than trace.py
