gemini-cli-usage

Gemini CLI quota monitor. Fetches live Code Assist quota data from Google's backend when Gemini is using Google login.

Example output

gemini-cli-usage command:

Project: gemini-cli-usage
Auth: Google login
  gemini-2.5-pro        3.5% used  resets 19h38m
  gemini-2.5-flash-lite 0.07% used  resets 19h37m

gemini-cli-usage statusline command:

q:3.5% reset:19h38m

Install

uv tool install gemini-cli-usage

For local development from a checkout:

uv tool install .

Then run:

# Check usage once
gemini-cli-usage

# Raw JSON
gemini-cli-usage json

# Compact shell/statusline output
gemini-cli-usage statusline

# Force a fresh cache rebuild and print full status
gemini-cli-usage refresh

# Keep ~/.gemini/usage-limits.json fresh
gemini-cli-usage daemon

Commands

Data source

account_quota

When Gemini CLI is configured for Google login (oauth-personal), it calls Google's internal Code Assist API:

• loadCodeAssist
• retrieveUserQuota

This tool mirrors that flow using the OAuth credentials in ~/.gemini/oauth_creds.json.

Notes

• Quota fetches are best-effort. If auth is not Google login, or quota lookup fails, the tool reports the auth state plus the quota error.
• If the Google OAuth access token expires, the tool reuses Gemini CLI's installed OAuth client metadata when available. If Gemini is installed in a nonstandard location, set GEMINI_OAUTH_CLIENT_ID and GEMINI_OAUTH_CLIENT_SECRET, or rerun gemini and retry.
• status and json always build fresh data.
• statusline reads the cache by default; use --refresh or --max-age 0 to force a live refresh.
• refresh is a convenience command that rebuilds the cache and prints the full status output.
• Absolute quota counts are only shown when Google's response includes both remainingAmount and a usable fraction. Otherwise the tool reports % used plus reset time.
• Auth detection follows Gemini CLI precedence: environment variables first, then workspace .gemini/settings.json, then global ~/.gemini/settings.json.

Options

usage: gemini-cli-usage [-h] [--root ROOT] [--interval INTERVAL]
                        [--max-age MAX_AGE] [--refresh]
                        {status,json,daemon,statusline,refresh,install}

• --root ROOT: inspect a different project root instead of the current directory
• --max-age MAX_AGE: cache TTL for statusline
• --refresh: ignore the cache and rebuild fresh data where applicable
