Turn an existing system into an evidence-backed, intentional Screenplay `.play` model: interview and freeze agreement, provider-coverage inventory, `cratis screenplay generate`, approval-gated Prologue capture and interpret, bounded UI walks, targeted code reads, an evidence table with exact path:start-end locators that keeps unknowns, keep / change / remove decisions, re-slicing by business decision, a loss report and expert verification. Use for brownfield understanding, documentation 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
# Legacy extraction: from an existing system to a candidate model
## Purpose
Produce two separate things from a running or written system:
- **As-is evidence**: what the system demonstrably does today, with its source, strength and
open unknowns. Tools and code supply this.
- **Target decisions**: what the new model keeps, changes or removes, and why. People decide;
the agent proposes.
The deliverable is a *candidate* intentional `.play` model plus the evidence behind each part,
never a reconstruction: do not call it lossless, automatic or equivalent. Tools recover
structure, not intent, so a table write is a question ("why did this row change?"), not an
event. This is the legacy entry of `cratis-screenplay-modeling-lifecycle`: it replaces P1-P2,
then hands off to review (P5) and acceptance (P6).
## When to use / when not
- Use: understanding an inherited system, planning a modernization or migration, documenting
behaviour as Screenplay, reconciling `cratis screenplay generate` or Prologue output, planning a
side-car next to a frozen system (`references/side-car-migration.md`).

How to install
mdr add cratis/ai/cratis-screenplay-legacy-extraction@sha256:244874796e2e7f09The line at the top of this page pins the label git:20261019.79b4f4d, 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.
