Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

By tonydzi/second-brain-starter-kit (GitHub) · coding · 15 stars · scanned at commit 552cc75

- Mine GitHub, GitLab and git history for identities, infrastructure and leaked credentials using commit author emails, GitHub code search, the commit… Use when investigating a developer or organisation on GitHub, finding leaked API keys, AWS keys or tokens in code, enumerating org members and their personal repos, or recovering secrets deleted from HEAD but still present in history or forks

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/'secrets-in-git-history' ] || [ -L ~/.agents/skills/'secrets-in-git-history' ]; then echo 'A skill folder named secrets-in-git-history already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/tonydzi/second-brain-starter-kit' "$d" && git -C "$d" checkout --quiet '552cc7596c295452c208713bf5fa3c75d826f189' -- 'skills/secrets-in-git-history' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/secrets-in-git-history' ~/.agents/skills/'secrets-in-git-history' && 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/'secrets-in-git-history' ~/.claude/skills/'secrets-in-git-history' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
