Skill Authoring — easy-cheese conventions

This document codifies the skill-authoring rules for easy-cheese, drawn from obra/superpowers (CSO principle, Iron Law template, pressure-test gate) and Matt Pocock's skills repo (size budget, authoring checklist). It is the canonical reference for anyone adding or revising a skill.

Description rule (CSO)

The description is the only thing the harness shows the model when choosing a skill. Optimize it for triggering, not explanation.

The rule: sentence 1 = capability; sentence 2 = "Use when [triggering conditions]". No workflow summary, no pipeline-position prose, no feature list.
