Agent Usage Bar — Development skill for Claude Code

AgentUsageBar

A macOS menu bar app that tells you how much Codex and Claude quota you have left, what you spent locally, and when the window resets.

It is a trimmed rebuild of [CodexBar](https://github.com/steipete/CodexBar). CodexBar tracks a long list of agent CLIs; this one tracks two, Codex and Claude, and spends the room it saved on the parts you actually look at. One status item instead of a row of them. One card that fits on screen. Motion that comes from one curve rather than five.

What "trimmed" means

Every file adapted from CodexBar says in its header what it kept and what it dropped. The short version:

Kept	Dropped
Codex wham/usage, Claude /api/oauth/usage	Gemini, Antigravity, Factory, Warp
Session and weekly windows, credits	Spend controls, per-model rate limits, workspace resolution
Linear and historical pace models	Workday-weighted progress, run-out risk percentage
Local cost scan for both CLIs	Profile lookup, extra-usage billing, the web fallback
The capsule icon and its two decorations	Blink, wiggle, tilt, status overlays, the morph cache

What replaced them is motion. CodexBar's bar jumps to its new value; this one charges into it, and the number above it charges with it.

The menu bar item

Claude on the top row, Codex on the bottom. Left to right: full, half spent, nearly out, session window only, and stale after
