Provides sem semantic-diff detection, install-on-first-use, and fallback patterns. Use when building skills that consume git diff output.

Low-risk skills in the same category (coding) that look related. Check that one does what you need.

Install

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

if [ -e ~/.agents/skills/'sem-integration' ] || [ -L ~/.agents/skills/'sem-integration' ]; then echo 'A skill folder named sem-integration already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/athola/claude-night-market' "$d" && git -C "$d" checkout --quiet '4f94139a2d325f14442a62dc0b4cd28b41dbb5ba' -- 'plugins/leyline/skills/sem-integration' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/leyline/skills/sem-integration' ~/.agents/skills/'sem-integration' && 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/'sem-integration' ~/.claude/skills/'sem-integration' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
