Harness (revfactory)
A meta-skill that designs domain-specific agent teams and writes their skills.
Harness is a team-architecture factory for Claude Code. Ask it to build a harness for a project, and it turns your domain description into a team of specialised agents plus the skills they use. Install it through the plugin marketplace.
In the news
Launch · DeepSeek · Oct 2, 2026
DeepSeek releases a macOS and Windows Desktop app for DeepSeek Harness, its open-source agent harness where everything — tools, sub-agents, even the loop — is a plugin. The repo passed 240k stars within three months of its August launch, making it the fastest-growing harness in the field's history.

The Best of Agent Harnesses list ranks 167 agent harnesses weekly by capability, autonomy and recovery, ships an MCP server so agents can pick their own harness, and maintains a graveyard that flagged a 268k-star repo for suspected star manipulation. Curation itself becomes harness infrastructure.
Open Source · GitHub · Sep 29, 2026
EverMind AI releases Raven, a trusted, persistent, self-evolving multi-agent ecosystem built for recursive self-improvement — agents that modify their own harness under governance. The Show HN thread became a running debate on how much autonomy a harness should hand an agent over itself.
