Conciseness

The body is noticeably verbose for an always-loaded SKILL.md: delivery-mode rules are stated three or more times (Skill Configuration lines on 'sites-app'/'html' fallbacks, again under Workflow step 8, again under HTML Report Specifications and the Quality Bar), and waiver logic is repeated in nearly identical words ('Do not infer a waiver from the absence of the word "report"' vs. 'A user can explicitly waive report creation by...'). Dense multi-clause sentences like the 100+ word delivery-surface paragraph in step 8 carry redundant qualifiers. It does not fall to anchor 1 because it teaches genuinely non-obvious project policy rather than concepts Claude already knows, but the padding and repetition clearly exceed anchor 3's 'mostly efficient'.

Actionability

There are some concrete, executable anchors — 'npm run report:deliver -- --input artifact.json --output report.html', the 'validate_artifact' call, 'export_artifact_package' with project id and output_dir, and the bundled scripts/deliver_portable_artifact.mjs whose real usage string matches the documented command. But most guidance is directional rather than executable: 'Distill the report spine... write or mentally verify', 'Author artifact.json as a complete validate_artifact input' delegates the critical artifact.json schema to ../../src/analytics-app-core.md, which is absent from this bundle, so a reader cannot actually construct the payload from the skill alone. This matches anchor 3 ('some concrete guidance but incomplete; missing key details').

Workflow Clarity

The 10-step numbered Workflow is clearly sequenced (define job → read audience spec → gather evidence → spine → structure → standards → visuals → build surface → validate → hand off) with explicit validation checkpoints: step 9 'Validate the finished report... Review the rendered report itself', 'Fix the report before handoff when any of these checks fail', a closing 'Quality Bar' checklist, feedback loops ('If the selected MCP app report cannot be rendered after one targeted correction, fall back to html'), and blocker-recording instructions. This matches anchor 5's 'clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'.

Progressive Disclosure

Structure exists (Workflow, Report Standards, Quality Bar with one-level links like [executive-report.md](specifications/executive-report.md) and [mcp-app-report.md](specifications/mcp-app-report.md)), but judged against the actual bundle, those referenced files plus ../../src/analytics-app-core.md and ../../assets/demo-product-growth.csv are not present in the staged skill directory — only scripts/ exists. Meanwhile large blocks of surface-specific detail (the ~20-bullet HTML Report Specifications section and the long Narrative standards lists) are inlined in SKILL.md where they belong in the referenced specification files. This sits at anchor 3 ('some structure... content that should be separate is inline'), above anchor 2 because section headers and reference signals are present and navigation is possible.

Specificity

"Build polished analytical reports for executive, product, business, or technical audiences" names the domain plus essentially one concrete action (build reports) with audience variants; the rest of the sentence ("evidence-backed findings, visuals or tables, caveats, and source context") describes the report's contents rather than additional distinct actions like creating, revising, or exporting reports. This matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive' — below 4 because it does not list several specific actions, above 2 because the domain and output form are concretely stated.

Completeness

Both parts are explicitly present: what — "Build polished analytical reports for executive, product, business, or technical audiences"; when — "Use when the task needs a durable answer-first narrative with evidence-backed findings...". It does not reach anchor 5 because the 'when' clause is framed in spec vocabulary ("durable answer-first narrative", "source context") rather than concrete user trigger phrases, matching anchor 4's "'when' could be more explicit or specific". It is well above anchor 3 since the 'Use when' trigger is explicit, not merely implied.

Trigger Term Quality

Natural user-facing terms are present: "analytical reports", "executive", "product", "business", or "technical audiences", "visuals or tables", "caveats" — phrases a user asking for a report would plausibly say. It falls short of anchor 5 because common synonyms a user might naturally say (e.g., "write a report", "write-up", "memo", "brief", "summary document") are missing, and no file-format triggers exist; it is clearly above anchor 3's 'some relevant keywords but missing common variations'.

Distinctiveness Conflict Risk

"Analytical reports" with a defined audience set and evidence/caveat framing carves a fairly clear niche with explicit triggers, so it is 'mostly distinct' (anchor 4) — though there is minor overlap risk with adjacent data-analysis, dashboard, and document-writing skills that also involve tables, findings, and audiences. It is not anchor 5 because the wording does not sharply fence off those neighboring skills within the description itself, and not anchor 3 because the report-specific framing is substantially more specific than generic 'works with files' style overlap.
