Skill Prerequisite Check

Scan installed skills, discover their tool/MCP/auth dependencies via heuristic parsing, check if everything is installed and authenticated, and offer to fix issues interactively.

When to Use

• Setting up a new machine
• After installing new skills
• Verifying environment is ready for all skills
• Debugging "tool not found" errors during skill execution

Arguments

Parse from the user's invocation:

• Skill names: Any tokens after the command → filter to those skills only
• Default: scan all skills in ~/.claude/skills/ and .claude/skills/
