cratis-screenplay-model-review

cratis-screenplay-model-review is a skill for Claude Code, Codex from Cratis/AI. It costs 148 tokens per session (3,744 once invoked), scanned A, original, MIT.

A strict review method for Cratis Screenplay .play models and proposed changes. It checks structure, field origins, event-sourcing rules, scenario coverage, known anti-patterns, and whether each finding has a business consequence.

In plain words
What is it for?
Use it for self-checks, independent reviews, audits of extracted models, pre-render checks, or checking whether code has drifted from a model. It reports findings and fixes but does not change the model.
Why use it?
Models can look valid while describing incomplete or misleading behaviour. This review separates structural problems from meaning and business questions, so changes can be made deliberately rather than guessed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cratis-screenplay-model-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Screenplay model review

Purpose

Judge a model strictly and report; never fix it. Structure first (tools), then meaning (people and reviewers). Every finding names where it is, which rule it breaks, what goes wrong for the business if it stays, and a fix. Defects are kept apart from business questions. The same skill gives the modeler a quick self-check (P4), a reviewer the full audit (P5) and an explainer the business-question pass. The method follows the phased TrogonStack validation checklist, adapted to .play declarations (references/provenance.md).

When / when not

  • Use: P4 self-check; P5 independent review; auditing an existing or extracted model; reviewing a proposal or edit request before it is applied; checking a model before rendering; checking a code diff in a repository with a model for model-first drift (checklist R1; conform is structural only).
  • Use: explaining a feature or a planned change slice by slice, read-only (references/walkthrough.md).
  • Not for: changing the model (return findings; the modeler or the main session edits); writing missing specs (cratis-screenplay-scenario-coverage); designing slices (cratis-screenplay-slice-design); stream and invariant redesign (cratis-screenplay-streams-and-consistency); reviewing C# or rendered code (cratis-code-review, cratis-application-slice-conformance); diagnosing a running system (cratis-chronicle-cli-operations).
  • Code: none, except evidence files a legacy packet cites by file:line.

Interview phase

Skip if the brief names the scope, the mode and the review kind; otherwise ask about scope and mode, review kind and independence, delivery (decides whether V2 to V5 are required) and known intent. Read references/interview-batch.md for the four questions and follow-ups. Unattended: assume visibly, write each assumption in the report header, and lower confidence.

Procedure

Hold the stance: critic. Apply every check; do not soften a finding because the model "mostly works" or its fix is large. Flag, never repair: do not quietly add missing structure on the model's behalf.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
