95 / 100 · Low risk

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

Split a large Claude Code or Codex plugin into a small core plus optional modules. Use for "split this plugin", "my plugin is too big", "reduce startup context", "Codex is omitting my skills", "core plus optional packs", or "publish part of my plugin separately". Covers marketplace subdirectory sourcing, the dependency field's silent-load behaviour, Codex adapter regeneration, and vendored-skill placement. Use agent-auditor to measure first and benchmark-skills to verify routing after.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'plugin-module-split' ] || [ -L ~/.agents/skills/'plugin-module-split' ]; then echo 'A skill folder named plugin-module-split already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/b-open-io/prompts' "$d" && git -C "$d" checkout --quiet 'f4b302aadb0c99023b03e1f1b38ffed3697fbedf' -- 'modules/plugin-kit/skills/plugin-module-split' && mkdir -p ~/.agents/skills && cp -R "$d"/'modules/plugin-kit/skills/plugin-module-split' ~/.agents/skills/'plugin-module-split' && 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/'plugin-module-split' ~/.claude/skills/'plugin-module-split' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
