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

By LeoYeAI/agent-master-skills (GitHub) · coding · 2,186 stars · scanned at commit 8f88f9a

Diagnose why an MCP connector that used to authenticate now fails: classify the fault as envelope, expiry, rotation clobber, binding, or poisoned cache before changing any code. Use when a token exchange succeeds but tool calls 401, when a connector silently degrades after a refresh, when multi-account setups return another account's data, or when re-authenticating fixes the problem only until the next refresh.

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/'mcp-oauth-triage' ] || [ -L ~/.agents/skills/'mcp-oauth-triage' ]; then echo 'A skill folder named mcp-oauth-triage already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LeoYeAI/agent-master-skills' "$d" && git -C "$d" checkout --quiet '8f88f9a0dd5a1075d4f0c7626f9d960844d57575' -- 'skills/mcp-oauth-triage' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/mcp-oauth-triage' ~/.agents/skills/'mcp-oauth-triage' && 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/'mcp-oauth-triage' ~/.claude/skills/'mcp-oauth-triage' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
