Prompt:
Use builtin tool_search to search for mcp__t3-code__preview_status in group pi-t3-mcp-extension. Then execute that exact canonical tool name through normal lazy activation: in eval run display(await tool["mcp__t3-code__preview_status"]({})). Preserve the hyphen in t3-code; do not use the underscore alias. Report the actual search result and execution output. Do not inspect files, run shell commands, change configuration, or work around an inactive-tool error. Stop after reporting the result.
