AI CLI Usage Checker
Check remaining quota and usage for AI coding assistants: Claude Code, OpenAI Codex, Gemini CLI, and Z.AI.
Uses the cclimits npm package.
When to Use This Skill
- User asks "how much quota do I have left?"
- User asks "check my usage" or "am I rate limited?"
- User wants to know which AI tool has capacity
- Before starting a large task, to verify quota availability
- User asks about token limits or remaining requests
Running the Command
# Check all tools (detailed)
npx cclimits
# Compact one-liner (5h window)
npx cclimits --oneline
# Compact one-liner (7d window)
npx cclimits --oneline 7d
# Check specific tools
npx cclimits --claude
npx cclimits --codex
npx cclimits --gemini
npx cclimits --zai
# JSON output (for scripting)
npx cclimits --json
Credential Locations
Credentials are auto-discovered from these locations:
| Tool | Location |
|---|---|
| Claude | ~/.claude/.credentials.json (Linux) or macOS Keychain |
| Codex | ~/.codex/auth.json |
| Gemini | ~/.gemini/oauth_creds.json (auto-refreshes) |
| Z.AI | $ZAI_KEY or $ZAI_API_KEY environment variable |
Setup (One-Time)
If credentials are missing, run the corresponding CLI tool to authenticate:
claude # Login to Claude Code
codex login # Login to OpenAI Codex
gemini # Login to Gemini CLI
export ZAI_KEY=your-key # Add to ~/.zshrc
Output Interpretation
Quota Windows
Most tools use rolling windows:
- 5-hour window: Short-term rate limit
- 7-day window: Weekly quota limit
Percentage Used
- 0-50%: Plenty of capacity
- 50-70%: Moderate usage, plan accordingly
- 70-90%: High usage, may want to switch tools
- 90-100%: Near limit, expect rate limiting
Status Icons
| Icon | Meaning |
|---|---|
| ✅ | Under 70% - plenty of capacity |
| ⚠️ | 70-90% - moderate usage |
| 🔴 | 90-100% - near limit |
| ❌ | 100% or unavailable |
Gemini Tiers
Gemini models are grouped by quota tier (models in same tier share quota):
| Tier | Models |
|---|---|
| 3-Flash | gemini-3-flash-preview |
| Flash | gemini-2.5-flash, gemini-2.5-flash-lite, gemini-2.0-flash |
| Pro | gemini-2.5-pro, gemini-3-pro-preview |
Example Output
Compact One-liner (--oneline)
Claude: 4.0% (5h) ✅ | Codex: 0% (5h) ✅ | Z.AI: 1% ✅ | Gemini: ( 3-Flash 7% ✅ | Flash 1% ✅ | Pro 10% ✅ )

Troubleshooting
"No credentials found"
- Run the CLI tool to authenticate (see Setup section)
- For Z.AI, ensure environment variable is set
"Token expired"
- Claude: Run
claudeto re-authenticate - Codex: Run
codex login - Gemini: Run
gemini(or wait for auto-refresh)
API errors
- Check internet connectivity
- Verify the CLI tool works directly
- Check if the service is down
