Conciseness

The guidance is mostly non-obvious domain-specific instruction rather than concepts Claude already knows, but there is meaningful repetition that could be tightened: run-mode rules ('first-run', 'incremental', 'overwrite' semantics) appear in the Inputs table, 'Resolve Existing Mockup And Run Mode', and again in Workflow steps 8; launcher/child-screen preservation rules are restated across 'Rationalize Multiple Modules', 'Preserve Action And Child-Screen Semantics', and 'Implement The Mockup'; evidence-coverage rules appear in both the inventory section and 'Validation'. This fits the 3 anchor ('mostly efficient but includes some unnecessary explanation or could be tightened') better than the 4 anchor's 'minor instances'.

Actionability

Concrete, executable guidance throughout: exact paths ('agentic-sdlc-data/tenants/<tenant>/projects/<project>/repo', '<project-repo>/evidence/features/<module-name>/'), an input table with defaults, an enumerated disposition taxonomy ('preserved', 'moved', 'combined', 'replaced', 'omitted' / 'preserved-launcher', 'target-modal', ...), the named check sequence 'lint -> typecheck -> test -> build', 'git diff --check', named completion-gate variables, and the route to locate ('Reference -> Products -> Maintain Products'). Minor gaps keep it at 4 rather than 5: validation commands are named but not given as executable invocations (e.g., no 'npm run lint'), and the completion-gate counts are described but not computed by any script.

Workflow Clarity

The 15-step Workflow section gives a clear sequence with explicit validation checkpoints and a feedback loop: step 13 says 'return to the inventory and implementation steps, repair the mockup, and rerun the affected checks. Continue this internal refinement loop until all completion gates pass or a genuine evidence gap... prevents completion'. The Validation section adds a checklist, browser-test requirements per material action and LOV selection, and completion gates ('unsupported_surface_count = 0', etc.), matching the 5 anchor with error-recovery loops and checklists for a destructive-capable (overwrite) skill.

Progressive Disclosure

The body has clear section headers but is a ~296-line monolithic SKILL.md with no bundle files (no references/, scripts/, or assets/ exist), so there is no file-level progressive disclosure at all. Content that could live in separate reference files — the disposition taxonomy, the evidence-coverage checklist, the ownership-manifest schema, the completion-report template — is fully inlined. This fits the 3 anchor ('some structure but could be better organized; content that should be separate is inline'); it is above the 2 anchor because internal section structure is good and content is navigable, and below the 4 anchor because nothing is split out.

Specificity

The description lists multiple specific concrete actions with comprehensive coverage: 'Generate high-fidelity, functional Next.js mockup screens for Oracle Forms modernization', 'preserve legacy fields, tabs, grids, section organization, and business behavior', 'combine separate Maintain/Retrieve-style forms into a unified search, filter, add, edit, and delete experience', and 'extend a target Next.js application while matching its existing... visual and interaction conventions'. It clearly matches the 5 anchor ('multiple specific concrete actions; comprehensive coverage') and not the 4 anchor, which implies minor coverage gaps.

Completeness

Both questions are explicitly answered: the 'what' ('Generate high-fidelity, functional Next.js mockup screens for Oracle Forms modernization from one or more module evidence folders and linked screenshots') and the 'when' ('Use when asked to preserve legacy fields... or extend a target Next.js application while matching its existing Reference / Products / Maintain Products... conventions'). This matches the 5 anchor with concrete trigger phrases; the 4 anchor would require a weaker or less specific 'when' clause.

Trigger Term Quality

Good natural keyword coverage including 'Oracle Forms modernization', 'legacy fields, tabs, grids', 'Maintain/Retrieve-style forms', 'Next.js', and 'search, filter, add, edit, and delete'. A few natural terms users might say are missing, such as 'replatform', 'convert Forms to web', or 'modernize legacy screens', so it sits at the 4 anchor rather than the comprehensive 5 anchor with synonyms.

Distinctiveness Conflict Risk

A clear niche with distinct triggers: Oracle Forms modernization mockup generation tied to evidence folders, the Maintain/Retrieve form consolidation, and the specific 'Reference / Products / Maintain Products' convention. It would not naturally trigger for unrelated Next.js or general UI work, matching the 5 anchor ('clear niche with distinct triggers; minimal conflict risk').
