Description

LangSmith-native autonomous agent optimization plugin for Claude Code. Spawns multi-agent proposers that evolve prompts, routing, tools, and architecture in isolated git worktrees. Uses LangSmith Datasets, Experiments, and LLM-as-judge evaluation as the backend.

The plugin includes:

• 5 skills: setup, evolve, health, status, deploy
• 6 agent types: proposer, evaluator, critic, architect, consolidator, testgen
• 15+ Python tools for evaluation, analysis, and orchestration
• Hooks for session initialization

Happy to create a PR with the full plugin directory structure if that's the preferred format.
