Model Lens — Model-Driven Architecture Review

Review the change (or design) through four lenses adapted from Practical Model-Driven Enterprise Architecture (ArchiMate/TOGAF). It asks one question: does this code sit in the right place, do one job, depend in the right direction, and stay scoped? For what this skill is not — and which sibling skill to use instead — see "What this skill is NOT" in references/review-rubric.md.

How to run a review

1. Determine the diff/design under review (git diff, a branch, or a described plan).
2. Before walking the lenses, read references/review-rubric.md for the per-lens checklists; cite its provenance table when a finding is challenged.
3. Walk each lens; collect findings grouped by lens, with file:line, the layer, the rule, the fix.
4. Order findings by leverage; give a one-line verdict.
5. This lens reports; it does not auto-edit unless the user asks for fixes.
