Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

By huytieu/COG-second-brain (GitHub) · coding · 1,385 stars · scanned at commit 144c7a3

Closed-loop feature documentation for your product. Give it a feature (issue numbers or an id) and it reads the source, drives your live app to capture real screenshots and a screen recording, writes a docs article (Docusaurus or any markdown docs site) with both how-to steps and use-case content, then verifies the article with a fresh-context read-only verifier before reporting. Use when you say "write the doc for <feature>", "document issue #123", or "/feature-doc".

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'feature-doc' ] || [ -L ~/.agents/skills/'feature-doc' ]; then echo 'A skill folder named feature-doc already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/huytieu/COG-second-brain' "$d" && git -C "$d" checkout --quiet '144c7a3a959cc99538b7dfee9c22c4b065a0e156' -- '.claude/skills/feature-doc' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/feature-doc' ~/.agents/skills/'feature-doc' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'feature-doc' ~/.claude/skills/'feature-doc' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
