claude-oauth-renewal（Claude OAuth renewal 搜索）

Claude Code OAuth Auto-Renewal

Automatically detect and renew expired Claude Code OAuth tokens during OpenClaw heartbeat cycles. Prevents agent downtime caused by token expiration.

When to Use

✅ USE this skill when:

• Your OpenClaw agent uses Claude Code as the AI provider
• You want uninterrupted agent operation without manual token renewal
• You're running OpenClaw on macOS with Chrome browser

How It Works

3-Tier Renewal Strategy

Heartbeat triggers check-claude-oauth.sh
  │
  ├─ Token healthy (>6h remaining) → silent exit ✓
  │
  ├─ Tier 1: claude auth status (refresh token)
  │   ├─ Success → silent exit ✓
  │   └─ Fail ↓
  │
  ├─ Tier 2: Browser automation (osascript + Chrome JXA)
  │   ├─ Start claude auth login
  │   ├─ Auto-click "Authorize" on claude.ai
  │   ├─ Extract auth code from callback page
  │   ├─ Feed code back to CLI via expect
  │   ├─ Success → silent exit ✓
  │   └─ Fail ↓
  │
  └─ Tier 3: Alert user → agent notifies via configured channel

Token Storage

Claude Code stores OAuth tokens in macOS Keychain under the service name Claude Code-credentials. The token JSON includes:

• accessToken — API access token (prefix sk-ant-oat01-)
• refreshToken — Used for automatic renewal (prefix sk-ant-ort01-)
• expiresAt — Unix timestamp in milliseconds

Prerequisites

1. macOS with security CLI (Keychain access)
2. Claude Code installed and previously authenticated
3. Google Chrome with View → Developer → Allow JavaScript from Apple Events enabled (for Tier 2)
4. python3 available in PATH
5. expect available (ships with macOS)

Setup

1. Copy the script

cp skills/claude-oauth-renewal/scripts/check-claude-oauth.sh scripts/check-claude-oauth.sh
chmod +x scripts/check-claude-oauth.sh

2. Add to HEARTBEAT.md

Add as the first step in your heartbeat execution:

## Execution Order

0. Run `bash scripts/check-claude-oauth.sh` — if output exists, relay as highest priority alert
1. (your other heartbeat checks...)

3. Test

# Normal check (silent if token healthy)
bash scripts/check-claude-oauth.sh

# Force trigger by setting high threshold
WARN_HOURS=24 bash scripts/check-claude-oauth.sh

Configuration

Troubleshooting

"无法读取 Claude Code token"

• Run claude auth login manually to establish initial credentials
• Verify keychain access: security find-generic-password -s "Claude Code-credentials" -a "$(whoami)" -g

Tier 2 (browser automation) not working

• Enable Chrome JXA: View → Developer → Allow JavaScript from Apple Events
• Or via CLI: defaults write com.google.Chrome AppleScriptEnabled -bool true (restart Chrome)
• Ensure you're logged into claude.ai in Chrome

JSON parsing errors

• The script uses regex extraction (not json.loads) to handle truncated keychain output
• If security -w truncates long values, the -g flag is used as fallback

Notes

• Tier 1 (refresh token) handles most cases silently
• Tier 2 (browser) is only needed when refresh token itself expires (typically weeks)
• Tier 3 (alert) is the last resort when no automated renewal is possible
• The script never stores or logs actual token values
