Conciseness

The body is ~630 lines and spends ~100 lines cataloging ~30 frameworks (SWOT, PESTEL, Porter's Five Forces, BCG Matrix, etc.) with definitions Claude already knows, and the Phase 1 quality checklist is duplicated (once at '## Phase 1 Quality Checklist' and again under '## Quality Checklists'). It is not anchor 2 ('noticeably verbose' padded explanations throughout) because most content is genuinely additive — output templates, field tables, and formatting rules — but the framework catalog and duplication are unnecessary weight that could be trimmed.

Actionability

Nearly every step ships a copy-paste-ready template: the Framework Selection table, Chapter Skeleton format, Data Requirements table with a filled example row ('China skincare market size 2024'), the chart task list, the output path convention 'charts/chapter_{N}_{chart_index}.png', the full report structure template, and a complete worked Gen-Z Skincare example covering both phases. Instruction-only guidance is concrete and covers the common cases, matching the top anchor.

Workflow Clarity

Both phases are numbered step-by-step (1.1–1.6, 2.1–2.5) with an explicit handoff section between them, explicit validation in Step 2.1 ('cross-reference against P0 requirements', 'If any P0 data is missing, note it and flag'), a Step 2.5 self-check, error-recovery fallbacks ('If any chart generation fails... fall back to comparison tables'), and per-phase checklists. This is the anchor-5 pattern of sequence + validation + feedback loops + checklists.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/ directories) and the entire skill is a single monolithic ~630-line file. Internal section structure is good, but content that clearly belongs in separate files — the ~30-framework catalog and the full worked example — is inlined, which matches anchor 3 ('content that should be separate is inline'). It is not anchor 2 because the document is well-sectioned and navigable, and not anchor 4 because nothing at all is offloaded to reference files.

Specificity

Quotes multiple concrete actions with named components: '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'. Coverage is comprehensive for the skill's scope; it does not fit anchor 4 because no meaningful capability gap remains, and it is far above anchor 3's '1-2 concrete actions'.

Completeness

Explicitly answers both questions: 'what' via 'This skill operates in two phases — (1) generating a structured analysis framework... (2) after data collection by other skills, producing the final consulting-grade report...' and 'when' via 'Use this skill when the user requests to generate, create, or write professional research reports...'. Matches the anchor-5 example structure exactly.

Trigger Term Quality

Natural user phrasing is covered with many synonyms: 'generate, create, or write professional research reports', 'market analysis, consumer insights, brand analysis, financial analysis, industry research, competitive intelligence, investment due diligence'. These are the exact terms a user would say; anchor 4 ('a few natural terms missing') is too low a fit.

Distinctiveness Conflict Risk

The phrase 'including but not limited to... or any consulting-grade analytical report' makes the trigger very broad, so it could overlap with general research, deep-research, or data-analysis skills. It is more specific than anchor 2's 'very broad' but has real overlap risk with closely related research skills, so anchor 4's 'minor overlap risk' does not fit.
