Usage Pacing

Check live rate-limit usage for Claude.ai and OpenAI/Codex plans, then apply pacing tiers to avoid hitting limits.

Scripts

`claude-usage`

Reads the Claude Code OAuth token from macOS Keychain and calls the Anthropic usage API.

# Human-readable output with color bars
scripts/claude-usage

# JSON output (for programmatic use)
scripts/claude-usage --json

Requirements:

macOS with security CLI (Keychain access)
Claude Code OAuth token in Keychain (run claude login to set up)
Token needs user:profile scope (standard Claude Code login provides this)

Token location: macOS Keychain, service Claude Code-credentials, account = your macOS username.

`openai-usage`

Reads the OpenAI OAuth token from OpenClaw's auth-profiles and calls the ChatGPT usage API.

# Human-readable output with color bars
scripts/openai-usage

# JSON output
scripts/openai-usage --json

Requirements:

OpenClaw with an authenticated openai-codex profile (run openclaw auth openai-codex)
Auth profiles at ~/.openclaw/agents/main/agent/auth-profiles.json

Pacing Tiers

Wire both scripts into your heartbeat to automatically pace work based on remaining budget:

Tier	Remaining	Behavior
🟢 GREEN	>50%	Normal operations
🟡 YELLOW	25-50%	Skip sub-agents, defer non-urgent research
🟠 ORANGE	10-25%	Essential replies only, no proactive checks
🔴 RED	<10%	Critical only, warn user

Heartbeat integration

Add to your HEARTBEAT.md:

## Usage pacing (every heartbeat)
- Run `scripts/claude-usage --json` and `scripts/openai-usage --json` to check rate limits.
- Store readings in memory/heartbeat-state.json under "usage.claude" and "usage.openai".
- Apply pacing tiers:
  - GREEN (>50% left): normal ops
  - YELLOW (25-50%): skip sub-agents, defer non-urgent research
  - ORANGE (10-25%): essential replies only, no proactive checks
  - RED (<10%): critical only, warn user
- If entering YELLOW or worse, mention it briefly when next messaging.
