ECC

The agent harness performance optimization system.

ECC is an Agent Skill — a folder with a SKILL.md and any helper scripts that a coding agent loads on demand. Drop it in your skills directory and the agent picks it up the next time the task matches.

Its source repo has about 245.1k stars, a rough proxy for how many people rely on it.

How to use it

  1. Copy the skill folder into your agent's skills directory, or run the add command above.
  2. Reload the agent so it re-scans available skills.
  3. Trigger it by describing the task — the agent loads the skill when it matches.
