Preflight Connection Validator
Validate external service connections and report a clear status table before proceeding with work.
Why this exists
Nothing wastes more time than getting halfway through a task only to discover an API key expired or an MCP server is down. This skill front-loads that pain — check everything first, fix what's broken, then start real work with confidence.
Services to validate
Check each of these in order. For each service, make the minimal request that proves authentication works.
1. GitHub (gh CLI)
Run gh auth status via Bash. Look for the "Logged in" confirmation line. Extract:
- Account name
- Active scopes
- Auth method (keyring, token, etc.)
