Skill Design

Work every mode the same way: pose a principle as a question about the skill in front of you — or the one taking shape — gather evidence from its files, and decide from the evidence. One question underlies all ten principles: can the executor close every decision delegated to it, using only what the skill provides? A decision closes when the executor can name the options on the table, the default included; tell the known facts from the assumed ones; rank the options by a stated rule; strike the options that fail a constraint; predict what follows from the option it favors; and see which act binds. Wherever the skill leaves one of those parts unsupplied, and gives the executor no way to find it, you have found work.

Building, testing, and packaging belong with skill-creator; deciding what a skill should be, and whether it holds up, belongs here. When the work turns to drafting a SKILL.md, running evals, tuning a description, or packaging, hand over to skill-creator.
