Shape Screenplay slices from a discovered timeline: commands with reachable, authorized origins and traced inputs, rules placed by layer, a per-command refusal inventory, events-vs-views decisions, read models per screen component with queries that follow the business view, Level-1 screens, field lineage, state-transition tables, slice dependencies and the next slice. Use when designing slices after discovery, adding a capability or deciding command inputs, rule placement, read-model shape or…

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 design

## Purpose

Turn a timeline of events into designed slices: for each fact, the command that records it and
where its data comes from; for each thing someone needs to see, the read model, query and
screen. Output: compiling `StateChange` and `StateView` slices in the chosen mode, a command
card and refusal inventory per command, a lineage matrix, a state-transition table per entity,
slice dependencies, and the rules the model records but cannot enforce yet.
Grammar: `cratis-screenplay-command-surface`, `cratis-screenplay-read-surface`,
`cratis-screenplay-projections`. Tools, versions and verdicts: `cratis-screenplay-toolchain`.
Lifecycle, modes and hand-offs: `cratis-screenplay-modeling-lifecycle`.

## When / when not

- Use after `cratis-screenplay-discovery`; for a new capability, command inputs, rule placement,
  read-model or query shape, screen data, lineage.
- Not for: which identity a fact belongs to and where invariants are enforced
  (`cratis-screenplay-streams-and-consistency`); reactions, todo lists, captures
  (`cratis-screenplay-automations-and-translations`); which scenarios to write
…

How to install

The exact contents, by fingerprint
mdr add cratis/ai/cratis-screenplay-slice-design@sha256:7b5b32ab3e904121

The line at the top of this page pins the label git:20261019.f9fbe79, 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.
