45ck Model Review Artifact
Use this skill when a human needs to inspect a system model, architecture view, dependency graph, workflow, or UML-style diagram.
Core Rule
Keep the model source durable and diffable. Use generated HTML only as the review surface.
- Canonical source: Markdown, TOON, specgraph, Mermaid text, PlantUML text, or project docs.
- Review surface: static HTML with pre-rendered inline SVG or static markup.
- Do not load Mermaid, PlantUML, or other diagram runtimes in generated review HTML by default.
Good Fits
- C4 context, container, component, dynamic, or deployment views.
- UML-style sequence, state, class/domain, activity, and use-case views.
- Architecture-space summaries: ownership, risk, quality attributes, dependencies, and decisions.
- Blast-radius views for proposed agentic changes.
- Generated dependency graphs derived from code, package metadata, specs, or traces.
Notation Guidance
- Mermaid sequence, state, and class diagrams are good source-backed diagram candidates.
- Mermaid C4 is useful for review, but mark its C4 level explicitly and do not treat the diagram as the only architecture authority.
- UWE UML is a modelling method, not a Mermaid-native contract. Keep UWE concepts in structured source and generate simplified review diagrams when useful.
- Dependency graphs should usually be generated from evidence rather than hand-maintained.
Required Metadata
- artifact type:
model-view,model-diff,architecture-view,blast-radius, orreview-dashboard - model id: stable identity across revisions when the project uses model policy checks
- model kind: sequence, state, class, domain, context, container, component, dynamic, deployment, dependency, use-case, activity, or architecture-space
- notation
- method when relevant: uml, uwe, or c4
- facets when relevant: UWE content, navigation, presentation, process, access, or adaptation
- abstraction level: domain, design, runtime, deployment, or decision
- canonical source path
- generated review path, if any
- evidence links
- owner
- freshness data: source hash, renderer, renderer version, and generated timestamp when available
- for model diffs: before artifact id, after artifact id, diff method, lineage, and generated review path
Process
- Identify the question the model must answer.
- Pick the model kind and abstraction level.
- Choose the canonical notation and source path.
- Name the evidence that backs the model.
- Decide whether a generated HTML review surface is useful. When
--enable-modelingis active, pair authored model sources with generated HTML review surfaces undergenerated/review/models/. - Record the artifact in
docs/artifacts/artifacts.manifest.json. - If HTML is generated, pre-render diagrams and run the artifact checks. When model policy checks are scaffolded, also run
node scripts/check-model-artifact-policy.mjs.
