How It Works
Checkup
/quack:checkup measures what your setup loads into every message.
Some things are paid again in every single message: memory files
(CLAUDE.md), skill descriptions, MCP server tools, settings. /quack:checkup
measures them and suggests fixes.
What it looks at:
- memory files and how long they are (the Claude Code docs suggest under 200
lines for
CLAUDE.md); - skill descriptions loaded from plugins and folders;
- MCP servers and how many tools they add;
- settings that change cost.
It can also set up:
- a status line with context use and cost;
- a compact limit for 1M-context models, so long chats get summarized before they grow too large.
Only with your OK
The checkup proposes each fix and applies only the ones you approve.
