Claude Code usage monitor for Mac: see where your tokens go

SkillKeeper is a Mac menu bar app that reads the transcripts Claude Code keeps on your machine and shows where the tokens went: which skill, subagent, tool, MCP server, memory file or session. The header shows how much of your 5-hour and weekly limit is used and when it resets. The last 5 hours and 24 hours are free; longer history needs a $19 one-time license.

If you only want a gauge for your limit, there are good free open-source ones, and the comparison says which. This page is for the other question: what is eating the limit.

What a Claude Code usage monitor should answer

There are two different questions behind "how much am I using".

• How much. How close you are to the 5-hour or weekly limit, and when it resets.
• Where. Which source took the tokens, so you know what to change.

Claude Code answers the first one with /usage, and since it added attribution it answers part of the second too. A menu bar monitor is useful when you want the answer without opening a session, over a longer period, and with every source in one place. For a side-by-side with the built-in command, see SkillKeeper vs /usage.

What SkillKeeper shows

• Tokens by source. Separate lists for skills, agents, tools, MCP servers, commands, memory files, plugins and sessions, plus an All list where a heavy MCP server and a heavy skill sit side by side.
• Four time windows. The last 5 hours, 24 hours, week and month, with a chart where hovering a row lights up its share.
• Your limit in the header. How much of the 5-hour and weekly limit is used, and the time until reset.
• Heavy chats. Rows for expensive sessions show the context against the /compact line, and the menu bar icon turns orange when a chat nears its model's context limit.
• What never runs. The Skills tab splits skills into used and unused, with the length of each description, because that text is read on every request.

A typical use: the weekly limit is almost gone, you open the menu bar popup, switch to the week window, and see that one MCP server or one oversized CLAUDE.md is the biggest line. Why Claude Code burns through tokens goes through what to do about each cause.

Beyond monitoring

SkillKeeper can also change things, which a pure gauge does not do. It edits trigger phrases and descriptions in the real SKILL.md files, pauses or archives skills you do not use (archiving moves the folder, so it can be restored), and warns from the bell when a limit will run out before its reset or when a skill's description is longer than the limit.

Other tools it reads

Claude Code gets the full breakdown. Codex and Gemini CLI are shown by skill and session, one tool at a time. Cursor keeps its token counts on its own servers, so for Cursor SkillKeeper shows skill counts only. Per tool: Codex CLI, Gemini CLI, Cursor.

Free and paid

• Free after the trial: the last 5 hours and 24 hours, and search.
• Trial: every feature for 3 days from install, one trial per computer.
• License: $19 once, no subscription. It unlocks week and month history, skill editing and notifications, and covers the Mac app on up to 2 Macs plus the mod below.

Privacy

Skill contents and transcripts never leave your Mac; the app reads ~/.claude/projects/ and ~/.claude/skills/ locally and sends only anonymous usage counts. The privacy page lists exactly what it reads and writes.

Install

The app is a direct download for macOS 13 or later, signed and notarized by Apple. Get it from the home page. On Windows or Linux, use the Claude Code mod instead: Claude Code usage monitor for Windows and Linux.
