Conciseness

The body is lean and every sentence conveys repo-specific knowledge Claude could not infer (fixture storage convention, semantics-preserving trimming of large responses, exact fixture and example paths, the includeRawChunks/saveRawChunks mechanics). It explains no general concepts and includes no padding, matching the anchor 'Lean and efficient; assumes Claude's competence; every token earns its place'.

Actionability

Both workflows ship copy-paste-ready TypeScript that imports real repo helpers (run, saveRawChunks), and the streamText section even gives the exact execution command ('pnpm tsx src/stream-text/<provider>/<script-name>.ts') and output location. The examples cover the two common cases (doGenerate and doStream), matching the anchor 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

Each flow has a clear sequence (place script in the provider directory, run it, copy the logged/saved output into a renamed fixture), and the streamText path states the run command and output folder explicitly. It stays at 4 rather than 5 because the generateText flow implies running the script without stating the command, and there is no checkpoint confirming a fixture was created correctly; it is above anchor 3 because both sequences and their artifact destinations are explicit rather than implicit.

Progressive Disclosure

This is a short (~45 line) single-purpose skill with no need for external bundle files, and the content is organized into clearly scoped sections (conventions, generateText, streamText). Per the rubric's simple-skill guidance, well-organized sections alone warrant a 5; the in-body pointers to real repo paths (fixture folder, test file, /examples/ai-functions) aid navigation without any nested references.

Specificity

The description names the domain ("API response test fixture") via a single generic verb "Capture" with no enumerated actions, matching the anchor 'Names the domain but actions are minimal or generic' (cf. "Processes PDF files"). It does not reach 3 because no concrete actions beyond the single capture verb are listed, and is above 1 because the domain itself is named rather than being pure abstraction.

Completeness

The description offers a vague noun-phrase 'what' ("Capture API response test fixture") and contains no 'when' guidance whatsoever; the judging guidelines explicitly cap completeness at 3 for a missing 'Use when...' clause, and this case fits anchor 2 ('Has a vague what and no when'). It is above anchor 1 because the what is at least topic-specific, but cannot reach 3 without either explicit actions or a use-when trigger.

Trigger Term Quality

Only "API response" and "test fixture" appear — a couple of relevant but terse keywords with no natural phrases or variations a user would actually say (e.g. "provider responses", "raw response", "fixtures for provider tests"). This matches anchor 2 ('One or two generic keywords; missing the natural phrases users say'); it is above anchor 1 because the terms are domain-relevant rather than entirely generic, and below anchor 3 because common synonyms and variations are absent.

Distinctiveness Conflict Risk

"Capture API response test fixture" is a fairly specific niche (response parsing tests), so it would not conflict with virtually any skill, matching anchor 3 ('Somewhat specific but could still overlap with similar skills'). It does not reach 4-5 because without trigger phrases or scope markers it could plausibly fire for other API-testing or test-data skills.
