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

Refreshes the Claude Code docs baseline, runs the conformance check, and recommends schema and rule updates. Use when asked to "check for upstream changes", "check schema drift", "are our schemas up to date", or "what is new in Claude Code".

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/'check-upstream' ] || [ -L ~/.agents/skills/'check-upstream' ]; then echo 'A skill folder named check-upstream already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/pdugan20/claudelint' "$d" && git -C "$d" checkout --quiet 'a5508374a56d9206beae809e3398f3c48750af89' -- '.agents/skills/check-upstream' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/check-upstream' ~/.agents/skills/'check-upstream' && 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-upstream' ~/.claude/skills/'check-upstream' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
