How to use it

Pick the model and agent that match the task pressure: coding, documents, automation or private local work.

Attach only the MCP servers needed for that workflow and verify permissions before exposing files or secrets.

Run the pack checklist before delivery so prompts, rules and validation steps stay consistent.
