ECC Is Now the Largest Agent-Harness Repo on GitHub at 239,125 Stars, Shipping 284 Skills, 67 Agents and a 1,282-Test Security Scanner Across 12 CLIs
GitHub·high signal
affaan-m/ECC has reached 239,125 stars and 36.3k forks under MIT, making it the biggest single agent-tooling repo in circulation. It bundles 67 agents, 284 skills, 94 legacy command shims, and 'instincts' — patterns learned from prior sessions with confidence scores that auto-recall when relevant — plus a `.ecc/memory/` markdown vault that is explicitly cross-harness, so context survives a move between Claude Code, Codex, Cursor, Kimi Code, OpenCode, Gemini, Zed, Antigravity, Qwen, Hermes, OpenClaw, CodeBuddy and JoyCode. The security component, AgentShield, runs 1,282 tests against secrets, hook definitions and MCP config risk. Version 2.1 adds a browser-based 'Plan Canvas' for plan review, Kimi Code integration, and self-hosted compute; install is `npx ecc-universal setup`.
