Writing Workflow Skills

The authoring checklist for workflow skills in packages/pi-thinkrail-workflow. It carries the what to do; every why — the concept model, the three roles, the meta-rules cited as "(rule N)" below — lives once in the workflow-system spec beside this directory, skills/SPEC.md. Read that spec first; where this checklist and that spec disagree, the spec wins.

Workspace guard. This checklist edits packages/pi-thinkrail-workflow in the thinkrail repo. If that package is not in the current workspace (a ThinkRail-managed project, where these skills are a read-only staged cache), the family cannot be extended from here: say so in one line and stop — the terminal state for foreign workspaces.
