Agent Skill (SKILL.md) file paths · explicit static paths only, no globs and no templates. They follow the agentskills.io shape, and are loaded at compose time and injected into the system context. One of 62 words the served contract declares, projected from workflow.schema.json, the same file your editor validates against.

Descriptions are the schema's own; the deeper invariants (value languages and regexes) ride the same projection. A miss is a nika check finding before anything runs.
