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

bash

# 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:

bash

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% ✅ )
