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

Validates Claude Code settings.json files for schema, permissions, and security. Use when user asks to "check my settings", "validate settings.json", "permission errors", "environment variable issues", or "settings syntax errors". Validates model names, permission rules, hooks configuration, and environment variables.

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/'validate-settings' ] || [ -L ~/.agents/skills/'validate-settings' ]; then echo 'A skill folder named validate-settings 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 "$d" checkout --quiet 'a5508374a56d9206beae809e3398f3c48750af89' -- 'skills/validate-settings' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/validate-settings' ~/.agents/skills/'validate-settings' && 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/'validate-settings' ~/.claude/skills/'validate-settings' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
