Remove a prompt source
AI agents call sources_remove to permanently remove resources in Claude Role Library — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion operation on prompt sources stored in the YAML-based local-first architecture. Removing a source cannot be undone without restoration from backup, making this a destructive action.
From the tool's definition Tool name is 'sources_remove' with description 'Remove a prompt source'. The verb 'Remove' indicates irreversible deletion of data.

Register the Claude Role Library MCP server in PolicyLayer and add a rule for sources_remove: 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 Claude Role Library. Nothing to install.
sources_remove 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 sources_remove 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 sources_remove. 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.
