An approved way of working
Provide the procedure, current templates and examples the team considers correct. A skill can encode those decisions; missing policy, prices or approval authority must be resolved by the process owner.
The intended Claude product
Name Claude Code, claude.ai or an API-based application. Skill availability, installation, sharing and runtime capabilities differ. A package tested in one surface is not assumed to work unchanged in another.
Output and review boundaries
Specify where the draft belongs, who checks it and which actions require confirmation. Connected tools need separate access. Installing instructions does not authorize sending emails or changing business records.
