check

82 / 100 · Low risk

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

By melodic-software/claude-code-plugins (GitHub) · coding · 30 stars · scanned at commit 677e798

Build, test, and lint verification for changed files across detected ecosystems (.NET, Python, TypeScript, Go, Bash, PowerShell, Markdown), with the project's own commands overriding bundled defaults. Use when: 'does it compile', 'run tests', 'build it', 'run the tests', 'does this still build', 'check it', or after any code edit. Lint only: /toolchain:lint; outcome verification: /verification:confirm.

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/'check' ] || [ -L ~/.agents/skills/'check' ]; then echo 'A skill folder named check already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/toolchain/skills/check' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/toolchain/skills/check' ~/.agents/skills/'check' && 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/'check' ~/.claude/skills/'check' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
