Conciseness

The ~85-line framework encyclopedia explains concepts Claude already knows (e.g., "SWOT Analysis | Strengths, Weaknesses, Opportunities, Threats"; "PEST / PESTEL Analysis | Political, Economic, Social, Technological"), and content is duplicated — the Phase 1 Quality Checklist appears twice (once after Step 1.6, again under "Quality Checklists") and the Step 1.6 assembly template re-prints the output formats already shown in Steps 1.2–1.5. This matches the 2 anchor ("Noticeably verbose; several unnecessary explanations or padded sections") rather than 3, because the padding is more than incidental; it is not 1 since the core operational guidance (phase workflows, data-requirement schemas, chart pipeline) is genuinely non-obvious and earns its tokens.

Actionability

For an instruction-only skill the guidance is fully executable: copy-paste-ready markdown templates (Data Requirements table with example rows "China skincare market size 2024 2025" | P0 | 2020-2025), a concrete file-path convention ("charts/chapter_{N}_{chart_index}.png"), a specific citation standard (GB/T 7714-2015), an explicit chart-task extraction table, and a worked Gen-Z skincare example covering the common end-to-end case. This matches the 5 anchor ("copy-paste ready... specific examples cover the common cases"); the only dependency — delegating to a visualization skill — is handled with concrete invocation details and fallbacks, so there are no minor gaps that would justify a 4.

Workflow Clarity

Both phases are clearly sequenced (Step 1.1–1.6, handoff section, Step 2.1–2.5) with explicit validation checkpoints (Step 2.1 input validation against P0 requirements, Step 2.3 chart validation step 5, Step 2.5 final structure self-check) and error-recovery feedback loops ("If any chart generation fails, note it and fall back to comparison tables for that sub-chapter"; "If any P0 data is missing, note it in the report and flag for the user"), plus per-phase quality checklists. This is a direct match for the 5 anchor ("Clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes").

Progressive Disclosure

Internal structure is strong (clear phase headings, step hierarchy, tables), but the skill is a 624-line single file with no bundle at all — no references/, scripts/, or assets/ directories exist — and substantial content that belongs one level deep is inlined: the framework catalog, the GB/T 7714-2015 citation specification, and the full illustrative Gen-Z example. This matches the 3 anchor ("Some structure but could be better organized... content that should be separate is inline") rather than 2, since the in-file organization is good and easy to navigate, but not 4 because a skill of this size should split its reference material into separate files.

Specificity

Quotes multiple concrete actions — "generating a structured analysis framework with chapter skeleton, data query requirements, and analysis logic" and "producing the final consulting-grade report with structured narratives, embedded charts, and strategic insights" — which comprehensively cover what the two-phase skill does. This matches the 5 anchor ("Lists multiple specific concrete actions; comprehensive coverage") rather than 4, since there are no meaningful gaps in the action coverage.

Completeness

Explicitly answers both questions: "Use this skill when the user requests to generate, create, or write professional research reports..." (when, with concrete trigger phrases) and the two-phase capability description (what). This is a direct match for the 5 anchor ("Clearly and explicitly answers both what AND when with concrete trigger phrases"); the 4 anchor requires a 'when' that is less explicit, which does not apply here.

Trigger Term Quality

Natural trigger terms are comprehensively covered: "market analysis, consumer insights, brand analysis, financial analysis, industry research, competitive intelligence, investment due diligence" plus the verb phrases "generate, create, or write professional research reports". These are exactly the phrases a user would say (matching the 5 anchor's "including synonyms"), with no meaningful natural variants missing; 4 would require identifiable missing common terms, which there aren't.

Distinctiveness Conflict Risk

The consulting-grade, framework-to-report pipeline niche is mostly distinct, but the catch-all "or any consulting-grade analytical report" and the broad domain list create minor overlap risk with generic deep-research or report-writing skills. This fits the 4 anchor ("Mostly distinct; minor overlap risk with closely related skills") rather than 5, since the breadth of domains slightly raises conflict risk beyond "minimal".
