Installation and loading troubleshootingLimitations & considerations
- Diagrams persist locally with last-save-wins behavior
- Can fill the prompt and copy component IDs
- Desktop compatibility was not runtime-tested in this source review
Mods execute with your user privileges and are not sandboxed. They can access files, launch processes and make network requests. ClaudeStack has not run or security-audited this Mod. Use claude plugin validate on a downloaded directory to inspect declared behavior; validation does not certify safety. Check the official trust guidance before loading it.
