Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By SethGammon/Citadel (GitHub) · coding · 929 stars · scanned at commit 3c317a0
Structural codebase index generator. Builds a compact JSON map of files, exports, imports, dependency graph, and roles. Queryable by keyword. Injected into fleet agents as context slices to reduce token usage on code navigation.
Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'map' ] || [ -L ~/.agents/skills/'map' ]; then echo 'A skill folder named map already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/SethGammon/Citadel' "$d" && git -C "$d" checkout --quiet '3c317a0bf13f147efaa695db7c24117349119d07' -- 'skills/map' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/map' ~/.agents/skills/'map' && 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/'map' ~/.claude/skills/'map' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
