Agent tool calls failing validation errors | Friends of the Crustacean 🦞🤝 | Page 1

Hello! I'm having issues with my agent running tool calls. Below are some additional details:

All tool calls are failing with parameter validation errors despite parameters being provided correctly. The tools appear to receive empty parameter objects {} instead of the actual arguments passed by the agent.

Affected Tools

read - Cannot read files
write - Cannot write files
exec - Cannot execute commands
message - Cannot send messages

Error Messages

read: "Missing required parameter: path (path or file_path)"
exec: "command: must have required property 'command'"
write: "content: must have required property 'content'"
message: "action: must have required property 'action'"

Steps to Reproduce

Agent attempts to call any tool with properly formatted parameters
Tool receives empty parameter object {}
Validation fails with "missing required parameter" error

Example Failed Calls

read tool:

{"file_path": "/home/ubuntu/.openclaw/workspace/knowledge/sheet.md"}

Result: "Missing required parameter: path (path or file_path)"

exec tool:

{"command": "cat /home/ubuntu/.openclaw/workspace/knowledge/recent.json"}

Result: "command: must have required property 'command'"

Environment

OpenClaw Version: 2026.3.23-beta.1
Model: kimi-coding/k2p5

Impact

Agent cannot access knowledge files
Agent cannot execute system commands
Agent cannot write to memory files
Agent cannot send Discord messages
Cron jobs completely non-functional

Additional Notes

Issue affects both interactive sessions and cron job execution
Parameters appear correctly formatted in agent code
Error suggests parameter object is not being passed to tool execution layer
May be related to JSON serialization or tool invocation pipeline
