Adds a new plugin that integrates with Weights & Biases Weave for
comprehensive LLM tracing and observability.
Plugin features:
- Full system prompt capture via new llm_request hook
- Multi-turn conversation tracing (all LLM requests)
- Tool call spans with inputs, outputs, duration
- Session lifecycle tracking
- Support for all LLM providers (Claude, GPT, Gemini, Bedrock, etc.)
- Self-hosted W&B instance support via baseUrl config
- Automatic project creation with RESTRICTED visibility
- Graceful degradation when core llm_request hook unavailable
Core changes:
- Add llm_request hook to plugin system for LLM payload observability
- Wrap streamFn in agent runner to capture requests to all providers
