Create Agent Harness
Generate a production-ready harness for AI agents (Claude Code and Devin CLI only) in a target repository. The harness is everything the model can't do alone.
Scope of this skill: only Claude Code and Devin CLI. Do not generate artifacts for OpenCode, Cursor, Gemini CLI, GitHub Copilot, or JetBrains AI — those agents are out of scope.
Core Principle
Agent = Model + Harness
Every harness component exists because the model can't do something on its own. Design for obsolescence — components become unnecessary as models improve. Two reliability loops guide the design:
- Feedforward — orient BEFORE acting (CLAUDE.md, rules, skills)
- Feedback — validate AFTER action (lint, tests, CI)
