Reconcile a Cratis slice's hand-written or gap-filled code and specifications with its contract (the `.play` slice and its specifications, else the agreed slice outline) in both directions: every contracted field, rule, event, read-model property and specification has a realization, and nothing in code lacks authority. Use when implementing a slice, re-delivering after a model change, finishing gap-fill after a render, or reviewing slice code. Not for: deciding what the slice should do…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Slice conformance: the code matches its contract, element by element

## Purpose

Hand-written code drifts from what was agreed in two directions: something agreed is
missing, or something nobody agreed is there. This skill is the check that closes both, plus
the rules for specifications, re-delivery and the final status. It does not decide what a
slice should do; the contract does.

Model-first rule: when a `.play` model covers the slice, the model is the contract and
the code is derived. Code is written only for scope the renderer rejects, adapters and
other infrastructure. Change behaviour in the model first, never in managed output.

## When to use / when not

- Use: implementing or finishing a slice by hand; gap-fill after a render; re-delivery after a
  model or outline change; reviewing slice code; a hand-over where "done" must mean something.
- Not for: the choice of behaviour (`cratis-screenplay-slice-design`,
  `cratis-chronicle-event-modeling`); how to write specifications
  (`cratis-application-slice-specifications`); the render workflow itself
  (`cratis-screenplay-render-and-gap-fill`).

How to install

The exact contents, by fingerprint
mdr add cratis/ai/cratis-application-slice-conformance@sha256:442c5b79db1f5ce6

The line at the top of this page pins the label git:20261013.e57d5c3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
