Awesome Agent Harness

Awesome Agent Harness

A curated list of practical resources for AI coding-agent harnesses, including skills and skill collections, agent systems and harness configurations, workflow systems, supporting tools, standards, and reference implementations. Covers Claude Code, Codex, Gemini CLI, OpenClaw, Hermes, and other coding-agent environments. Compatibility and installation requirements are project-specific; verify them in each linked repository.

Skills

Development Workflow

• Superpowers - Agentic software development methodology with skills for brainstorming, planning, TDD, debugging, code review, verification, and subagent-driven development.
• Agent Skills - Production-grade engineering skills for AI coding agents.
• planning-with-files - Persistent file-based planning for long-running agentic tasks across Claude Code, Codex, Hermes, and other SKILL.md-compatible agents.
• Karpathy-Inspired Claude Code Guidelines - Lightweight coding-agent guidelines for clearer assumptions, simpler code, surgical changes, and goal-driven execution.
• Matt Pocock Skills - Practical engineering workflow skills for coding agents. Standout skills include grill-me / grill-with-docs (relentless one-question-at-a-time interviewing to sharpen plans, clarify requirements, extract domain language, and eliminate ambiguity before implementation; widely praised on X as a "secret sauce" that dramatically improves results for both coding and real-world tasks) plus TDD, debugging, PRDs, architecture reviews, and handoffs. Actively maintained with npx installer.
• Waza - Engineering habits packaged as skills that AI agents can run.
• three-man-team - Structured Archit
