# Specs

> Up: [technical_specification.md](../technical_specification.md)

The top spec is the system root; this store holds the per-feature contracts under it. Every folder's
`index.md` lists ONLY its immediate children (at most 30); a spec over 150 lines is promoted to
`<slug>/index.md` + parts. Author a new spec from the skill's `SPEC_TEMPLATE.md`; the canon is the
engine's `references/specs.md`.
