[Bug] AutoClaw (macOS 2.0.2): schedule_task always rejected with "Invalid UUID" on internal commandId #924

Environment

• Product: AutoClaw (z.ai) macOS desktop app
• Version: 2.0.2 (com.zhipuai.autoclaw2)
• Platform: macOS (darwin, arm64)
• Credit: Reported by community user eskibars on Discord

Bug Summary

Every invocation of the schedule_task tool in AutoClaw fails validation and is rejected by the host before execution, making the task scheduling feature completely unusable.

Error Output

{
  "status": "rejected",
  "code": "[{\"origin\":\"string\",\"code\":\"invalid_format\",\"format\":\"uuid\",\"pattern\":\"/^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$/\",\"path\":[\"commandId\"],\"message\":\"Invalid UUID\"}]"
}

Root Cause Analysis

1. commandId is not present in the tool's public schema (label, schedule, action, policies). The caller does not supply commandId.
2. The failing value is generated internally on the host side.
3. At schema validation time, commandId appears to be undefined, empty, or unpopulated before the UUID regex validator runs.

Steps to Reproduce

Call schedule_task with a minimal valid payload:

{
  "label": "test",
  "schedule": { "kind": "at", "delayMs": 300000 },
  "action": { "kind": "agent_prompt", "prompt": "Reply READY." },
  "policies": {
    "misfire": { "policy": "run_once", "graceMs": 3600000 },
    "overlap": "skip",
    "retry": { "maxAttempts": 1, "backoffMs": 600000 }
  }
}

Expected: Task created and scheduled.
Actual: Rejected immediately with "Invalid UUID" on commandId.

Impact

Recurring and delayed agent workflows cannot run. Every scheduled task fails before instantiation.

Suggested Fix

Ensure commandId is assigned a valid UUID string before the schema validation layer executes on the host.
