raphaelchristi/harness-evolver
Automated harness evolution for AI agents. A Claude Code plugin that iteratively optimizes system prompts, routing, retrieval, and orchestration code using full-trace counterfactual diagnosis. Based on Meta-Harness (Lee et al., 2026).
ARCHETYPE
Orchestrator
A bench of specialised subagents. The main agent mostly delegates.
