ECC (Everything Claude Code)
Full agent harness + marketplace
FreePlanning & reasoninggithub.com
What it is
The largest harness here by volume: 68 agents, 285 skills, 94 slash commands, a security scanner for prompts and configs, session memory, and a browser-based Plan Canvas. Coordinates a fixed lifecycle: plan → test → implement → review → verify → remember → improve. ~241k stars.
Why it earns a slot
Powerful but maximal — installing this and superpowers and gstack at once means three competing methodologies. Pick one harness.
