Conciseness

The body is ~10 lean lines with no explanations of concepts Claude already knows. The only trimmable filler is the circular sentence "This skill is applicable to execute the workflow or actions described in the overview", which adds no information — a minor instance of over-explanation matching anchor 4 rather than 5's every-token-earns-its-place.

Actionability

Quotes: "Read [the detailed guide](references/detailed-guide.md) before executing this skill" is the only concrete directive; the body contains no code, commands, or Angular patterns, and the Limitations bullets are generic guardrails. This sits at anchor 2 ('minimal concrete guidance; high-level hints but missing the specific steps') — above anchor 1 only because the pointer is specific and actionable as an instruction.

Workflow Clarity

There is no sequenced workflow in the body — just 'read the guide first' — and no validation checkpoints beyond deferring to the guide ("Treat its safety, prerequisites, and validation requirements as mandatory"). The "When to Use" section is incoherent: it refers to "the workflow or actions described in the overview", but no such overview exists. Anchor 2 ('rough sequence present but many gaps; validation absent') is the best fit.

Progressive Disclosure

The single reference is real (references/detailed-guide.md, 513 lines), well-signaled, and one level deep (the guide itself contains no further file references), with load guidance ("For focused work, load the relevant sections; for end-to-end work, read the guide completely"). It falls short of anchor 5 because the body never names the guide's sections (loading states, error handling, data display), so 'load the relevant sections' gives no way to find them, and the three distinct pattern areas sit in one monolithic file.

Specificity

Quotes: "Modern Angular UI patterns for loading states, error handling, and data display" — names the domain and three concrete topic areas, but contains no action verbs, describing what the patterns cover rather than what the skill does. This matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive') better than anchor 4, whose example ('Extracts text from PDF files, fills forms, converts pages to images') lists several executable actions.

Completeness

Quotes: an explicit 'what' ("Modern Angular UI patterns for loading states, error handling, and data display") and an explicit 'when' ("Use when building UI components, handling async data, or managing component states"). Both are present, but the 'when' triggers are not Angular-scoped and the 'what' is topic-level rather than concrete actions, matching anchor 4 ('when could be more explicit or specific') rather than 5.

Trigger Term Quality

Quotes: "Use when building UI components, handling async data, or managing component states" plus "loading states, error handling" — these are phrases users would naturally say. Coverage is good but misses common variations like 'skeleton', 'spinner', 'empty state', or 'Angular Material', so it falls at anchor 4 rather than 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Quotes: "Modern Angular UI patterns" carves out a clear framework niche with distinct triggers, but "building UI components" and "managing component states" would also fire for React/Vue/generic-frontend tasks, giving minor overlap risk with closely related skills — anchor 4, not 5's minimal conflict risk.
