Conciseness

The body is dominated by lean, copy-ready code with almost no concept explanations Claude already knows — it assumes competence. It is not a 5 because the "Polling Pattern" section largely repeats the isUnexpected/poller/pollUntilDone sequence already shown in three earlier examples, and the closing line "This skill is applicable to execute the workflow or actions described in the overview" is pure filler.

Actionability

Every section is complete, executable TypeScript: both auth flows, URL and base64-local-file analysis, field extraction for invoices/receipts, model listing with paginate, custom model and classifier builds, and classification. Install commands and env vars make it copy-paste ready, matching the anchor for fully executable code covering the common cases.

Workflow Clarity

The numbered "Polling Pattern" section gives a clear sequence with an explicit error checkpoint (isUnexpected) and optional progress monitoring, and analysis flows are non-destructive so the destructive/batch cap does not apply. It falls short of 5 because there are no feedback loops for error recovery (what to do when polling fails or a field's confidence is low) and no verification step on results; it is above 3 because checkpoints are present, not merely implied.

Progressive Disclosure

The skill is a single ~320-line file with no bundle files, and substantial reference material is inlined — the prebuilt-model table, per-model field-extraction examples (invoice, receipt), and the "Key Types" import listing would fit better in a separate references file, mirroring the level-3 anchor of API-reference content that should be separate living inline. It is not a 2 because section headers keep the file navigable and nothing is buried, and not a 4 because no progressive disclosure exists at all beyond one flat file.

Specificity

The description lists several concrete actions — "Extract text, tables, and structured data" — qualified by "using prebuilt and custom models", matching the anchor for several specific actions with minor gaps. It is not a 5 because capabilities demonstrated in the body (classifying documents, building/training custom models, listing models) are absent, and not a 3 since more than 1-2 concrete actions are named.

Completeness

The 'what' is clear and concrete, but there is no 'Use when...' clause or equivalent trigger guidance, which per the judging guidelines caps completeness at 3. It is not a 2 because the 'what' is specific rather than vague, and not a 4 because the 'when' is entirely missing rather than merely weak.

Trigger Term Quality

Keywords present ("documents", "text", "tables", "structured data", "prebuilt and custom models") are relevant but miss the natural variations users actually say: "PDF", "OCR", "invoice", "receipt", or file extensions. This fits the anchor for some relevant keywords missing common variations/synonyms rather than the level-4 'good coverage with a few missing', since the most common user phrasings for this domain are absent.

Distinctiveness Conflict Risk

The phrase "using prebuilt and custom models" carves out a fairly distinct niche (model-based document analysis) with only minor overlap risk against generic PDF/document-library skills. It is not a 5 because the service name (Azure Document Intelligence), TypeScript, and domain terms (OCR, invoice, receipt) that would fully disambiguate it are missing, leaving some overlap with general document-extraction skills.
