Muster 1.1

Muster 1.1. Lighter, with costs you can trust and a 30-day usage view.

• Usage window. Choose Usage… in the menu bar menu to see 30 days of tokens and API-rate cost by day, model and project. It reads your transcripts only while the window is open.
• Costs counted once. A resumed Claude session no longer bills the history it copies, and subagent usage now counts toward the session that started it. Rows read "≈ $41 API" so nobody mistakes them for a bill, and Settings can show cost and tokens, tokens only, or nothing.
• Lighter. Muster now reads only what changed. With ten busy agents it averages about 0.4 % of one core and about 20 MB of memory.
• Answered elsewhere, gone here. If you answer a prompt in Claude's own dialog, Muster drops it right away instead of holding it for minutes.
• This week. Settings counts the prompts you answered without switching and the jumps you made.
• Safer hooks. Muster keeps your original settings file as settings.json.muster-original, leaves symlinks and permissions as they are, and redoes its edit if Claude writes the file at the same moment. A second copy of Muster can't take over your hooks, malformed requests can't crash it, and Codex waits at most 10 minutes if Muster stops responding.

Codex users: in Settings, under "Answer prompts from Muster", turn Codex off and on once to pick up the shorter wait, then run /hooks in Codex to trust the updated hook.
