Delete a Lucid document by moving it to the trash. This removes the ENTIRE document (there is no shape-level delete or in-place edit in the API). Useful for cleanup or the create-new-then-trash-old pattern.
AI agents call delete-diagram to permanently remove resources in Lucid — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes entire Lucid documents without recovery options. The description explicitly states it 'removes the ENTIRE document' and acknowledges there is 'no shape-level delete or in-place edit', indicating the action is all-or-nothing and irreversible. While moved to trash (not immediately purged), it constitutes a destructive action that cannot be undone through the API.
From the tool's definition 'Delete a Lucid document by moving it to the trash. This removes the ENTIRE document' — the tool irreversibly removes complete documents with no undo capability mentioned.

Block by default and require explicit approval.
Register the Lucid MCP server in PolicyLayer and add a rule for delete-diagram: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Lucid. Nothing to install.
delete-diagram is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete-diagram rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete-diagram. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
