Claude Code and Codex limits,
at a glance.

• Claude Code: type /usage to see your plan’s current session and weekly limits.
• Codex: type /status to see your 5-hour and weekly limits.
• Both answer when you ask, in that session’s terminal.

1. In Settings ▸ General, set Usage to Plan limits, or to Both to see what each session costs too.
2. Codex: nothing more to do. Gnista reads the limits Codex writes into its own session files.
3. Claude Code: nothing more to do. Claude Code only shares its limits with its status line, so Gnista joins it: with no status line, it adds one that prints nothing; with yours, it wraps it, and yours keeps working as before. To keep your status line to yourself, turn it off under Claude Code in Settings ▸ Agents.
4. Your limits show under your sessions, side by side: each agent’s icon, then a ring for each window, such as “◔ 5h 16%”. A window turns amber at 80% and red when it’s used up, and then says when it resets. Hover for the rest.

• No sign-in, no Keychain, no usage endpoint: the numbers come from the agents’ own files and status line, on your Mac.
• They update when an agent runs. Once a window has reset, the old numbers turn grey, marked with the time they’re from.
• Each session’s row has a ring for how full its context is, with any Usage setting but Off: amber at 80%, red when full. Hover for its tokens.
• Set Usage to Off, turn the status line off in Settings ▸ Agents, or disconnect Claude Code, and your status line goes back exactly as it was.
• Copilot shows its premium requests. Gemini CLI’s files carry no quota, so it shows none.
• Cost, if you want it: each session priced at its model maker’s list prices, from LiteLLM’s public price list, fetched at most once a day.

/usage and /status are free and exact, but only in the session you ask. Community tools such as ccusage estimate cost from Claude Code’s local logs, in the terminal.
