How to enable Claude live limits in JP the Cat
Claude Code does not persist its limit percentages, so JP shows them only after you opt in. Here is the exact flow.
Why it is opt-in
Unlike Codex, Claude Code does not write its rate-limit percentages to a file. The only source is the statusline stdin feed. JP never edits your config silently — you enable it explicitly.
The steps
Open JP the Cat → Settings → Live data → Enable Claude live limits. JP shows an acknowledgment, then appends a small, clearly-marked capture block to your statusline script (it reuses your existing stdin buffer and never rewrites `~/.claude/settings.json`). Turn it off and the block is removed. Until you opt in, Claude simply shows no limit gauge — never a wrong estimate.
Common questions
- Will this change my Claude Code settings?
- It appends a marked block to your statusline script only, and only when it finds a reusable stdin buffer. Disabling it removes the block.
- Can JP estimate Claude's limits instead?
- No — a token estimate cannot reproduce Claude's real limit percentage. Without the opt-in capture, JP shows no Claude gauge rather than a wrong one.
