Describe the Bug
When a user explicitly mentions a rule file with the @ syntax (e.g., @no-build-2.mdc), the rule is not made available to the AI via the fetch_rules tool. This breaks the expected “manual apply” workflow and forces inefficient workarounds.
Steps to Reproduce
Create a rule file (e.g., no-build-2.mdc) in the .cursor/rules directory
Do not add this rule to the agent_requestable_workspace_rules list
In a conversation with the AI, mention the rule with @no-build-2.mdc
Have the AI attempt to access the rule using fetch_rules([“no-build-2”])
Expected Behavior
The rule should be immediately available to the AI via the fetch_rules tool when explicitly mentioned with the @ syntax, regardless of whether it’s in the agent_requestable_workspace_rules list.
