Summary

After upgrading to OpenClaw 2026.3.24 on macOS, multiple tools stopped receiving their required parameters and failed validation.

Environment

• OpenClaw: 2026.3.24
• OS: macOS Darwin 25.4.0 (arm64)
• Session/channel: Telegram direct chat
• Models tested:
  • kimi/k2p5
  • openrouter/google/gemini-2.5-pro-exp-03-25:free
  • later session showed openai-codex/gpt-5.4

Symptoms

Several tools received empty payloads like {} even though the session/model was attempting to call them with arguments.

Examples:

• exec failed because command was missing
• read failed because path / file_path was missing
• gateway failed because action was missing

Representative errors:

• Validation failed for tool "exec": command: must have required property 'command'
• Missing required parameter: path
• Validation failed for tool "gateway": action: must have required property 'action'

What still worked

Not all tools were broken:

• session_status worked
• model switching worked
• after rollback, agents_list also worked

This suggests a partial regression in tool argument passing/binding rather than a total runtime failure.

Reproduction

1. Upgrade/install OpenClaw 2026.3.24
2. Start a normal session
3. Attempt tool calls requiring parameters, such as:
   • exec(command="pwd")
   • read(path="SOUL.md")
   • gateway(action="restart")
4. Observe that the tools receive {} / missing required fields

Troubleshooting attempted

• started a new session
• restarted gateway
• reinstalled OpenClaw
• changed models

None of the above fixed the issue.

Workaround / Resolution

Rollback to 2026.3.23 fixed the problem.

After rollback, smoke test passed:

• exec ✅
• read ✅
• session_status ✅
• agents_list ✅

Likely cause

Regression introduced in 2026.3.24 affecting parameter passing for some tool bindings/runtime paths.
