Conciseness

Mostly dense with genuinely project-specific guidance (library table, prefetch rule, naming conventions), but padded by meta-framework scaffolding that earns no tokens — the "SSL primitive" Actions table (READ/SELECT/WRITE/CALL_TOOL), the "Resource scope" table (CODEBASE/LOCAL_FS/PROCESS/NETWORK), and editorial asides like "they are not optional appendix material". Repeated re-references to `resources/tech-stack.md` and duplicated shadcn/tokens guidance could be consolidated, so it fits anchor 3 rather than anchor 4's "minor instances of over-explanation".

Actionability

Concrete and executable in the important places: exact commands (`rg --files`, the `rg "components/ui|shadcn|..."` search), named tools (`shadcn_search_items_in_registries`), versioned library choices (`next@16+`, `zod` v4, TailwindCSS v4), and naming examples (`order-summary-card.tsx`, `use-order-polling.ts`). The gap keeping it below anchor 5 is that verification is left abstract ("typically lint, typecheck, tests") rather than copy-paste ready commands, and key details live behind references.

Workflow Clarity

The Structural Flow gives a clear Entry → PREPARE/ACQUIRE/ACT/VERIFY/FINALIZE sequence with an explicit failure-and-recovery section ("If verification fails, fix before handoff or report the blocker") and a mandatory pre-handoff checklist — matching anchor 5's explicit validation steps, error-recovery feedback loops, and checklists. Not anchor 4: validation checkpoints are present and explicit at each stage, not merely "most" present.

Progressive Disclosure

Good structure: a clear "Stack Reference" table (File | Owns) signals what each referenced file covers, and detail is delegated to `resources/tech-stack.md`, `tailwind-rules.md`, `snippets.md`, and `angular-rules.md`. It falls short of anchor 5 because substantial policy detail (the full Libraries table, the long prefetch and Angular guardrail rules) is inlined in SKILL.md itself, and references fan out beyond one level — into other skills (`../_shared/core/*.md`, `../../rules/frontend.md`, `../oma-observability/SKILL.md`) — adding navigation burden.

Specificity

The description lists several specific capability areas — "components, pages, styles, forms, and frontend state or data flows" — anchored to concrete frameworks (React, Next.js, Angular), with only minor gaps (no mention of testing/accessibility work). It sits between anchor 3 (1-2 concrete actions) and anchor 5 (comprehensive), fitting anchor 4's "several specific actions; minor gaps" since the verbs themselves ("Implement or modify") are generic even though the object coverage is broad.

Completeness

It explicitly answers both: what ("Implement or modify web UI in React, Next.js, or Angular") and when ("Use for components, pages, styles, forms, and frontend state or data flows") — a present, explicit 'Use for...' trigger clause with concrete trigger phrases. Not anchor 4, because the 'when' clause could not reasonably be made more explicit or specific; not below 4 because no half of the what/when pair is missing or weakly implied.

Trigger Term Quality

Strong natural keyword coverage: "components, pages, styles, forms, frontend state, data flows" plus framework names users say (React, Next.js, Angular). A few natural synonyms are missing ("UI", "CSS", "Tailwind", "hooks", "responsive"), keeping it at anchor 4 rather than 5.

Distinctiveness Conflict Risk

Framework names (React, Next.js, Angular) and the "web UI" scope carve a clear frontend niche with distinct triggers, distinct from backend or document skills. Minor overlap risk remains with adjacent skills (generic web work, React Native/mobile, or a broader 'frontend' skill), so anchor 4 rather than 5.
