openclaw-qwen36-key-fix

Workaround for the Qwen 3.6 function-calling quirk where certain JSON keys get a spurious trailing colon or space (e.g. "name:" instead of "name").

Problem

Qwen 3.6 sometimes produces malformed tool call arguments:

{
  "action": "add",
  "job": {
    "name:": "my-reminder",
    "schedule:": { "kind:": "at", "at:": "2026-05-10T12:00:00Z" },
    "payload:": { "kind:": "systemEvent", "text:": "hello" }
  }
}

This causes OpenClaw's parameter validation to fail because the schema expects keys without trailing colons, spaces, or other non-alphanumeric characters.

Solution

This plugin hooks before_tool_call for the cron tool and recursively strips trailing colons, spaces and other non-alphanumeric characters from JSON keys before validation.
