Summary

The cron agent tool is not registered in the gateway tool registry. HTTP /tools/invoke returns "Tool not available: cron". The tool never appears in the model's tool definitions, despite passing sandbox policy.

The cron scheduler works fine — openclaw cron add/list via CLI works, jobs fire on schedule, delivery works. Only the agent-facing tool definition is missing.

openclaw sandbox explain confirms cron is in the allow list. No errors in gateway startup logs — the tool is silently absent.

Steps to reproduce

1. Config: cron.enabled: true, tools.sandbox.tools.allow includes "cron"
2. openclaw gateway restart
3. Start a new session (/new)
4. openclaw sandbox explain --session agent:main:main → cron in allow list ✅
5. Agent tool list does NOT include cron ❌
6. HTTP API confirms:

curl -sS http://127.0.0.1:18789/tools/invoke
-H "Authorization: Bearer $TOKEN"
-H 'Content-Type: application/json'
-d '{"tool": "cron", "action": "list", "args": {}}'

Response: {"ok":false,"error":{"type":"not_found","message":"Tool not available: cron"}}

Expected behavior

The cron tool should be registered in the gateway tool registry and injected into the model's tool definitions, allowing the agent to manage cron jobs directly.

Actual behavior

• Cron scheduler starts normally (logs: "cron: started, enabled: true, jobs: 1")
• CLI openclaw cron add/list/run works
• Sandbox policy allows cron
• But the tool definition is never registered — HTTP API returns 404, model never receives the tool
• No errors or warnings in gateway logs about tool registration
