drskill is "brew doctor for your agent's loadout", a CLI that audits the Skills and MCP servers your agents are loading. In can scan up to 34 issue categories like missing/duplicate descriptions, SKILL.md spec violations, secrets. It will also audit reads session traces to show which tools actually got called. I am using it in the lite mode, if you call --deep it configures litellm as a proxy and uses LLMs to do further analysis. It's cool.
Install drskill with:
uv tool install drskill
-or-
pip install drskill.
