The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.

ECC is an MIT-licensed system from affaan-m/ECC that installs into AI coding agent harnesses such as Claude Code, Codex, and several others, adding skills, specialized agents, persistent memory, and AgentShield security scanning around whatever large language model the harness already runs. The README positions it as developer productivity tooling for LLM agent development and agent performance tuning rather than a code generation tool itself, composing around whichever model the harness already calls.

yt-dlp is a Python command-line downloader that pulls audio and video from thousands of sites and hands post-processing off to ffmpeg. It's a fork of youtube-dl built for people who want fast fixes when a site breaks, not a polished app.

Ponytail is a skill that injects a code-minimalism ruleset into AI coding agents, teaching them to apply a seven-rung decision ladder before every code change. In benchmark tests against Claude Code editing a real FastAPI + React repo, it cut 54% of lines on average (up to 94% where agents over-built) while keeping every safety guard intact. Supports 16+ AI coding platforms and requires no config.
