Conciseness

Lean and dense throughout: every line carries project-specific knowledge Claude cannot infer (session cache-key pitfalls, alias collisions, binary-cache corruption, artifact paths, selector priority). No padding and no explanation of concepts Claude already knows — clear anchor-5 match.

Actionability

Fully executable, copy-paste-ready commands covering the common cases ("npx cypress open", "npx cypress run", a single-spec --spec smoke check, "npx cypress verify") plus concrete fixes in every gotcha (e.g., fixed fixture payloads, unique @alias names, data-testid priority). Matches anchor 5's 'copy-paste ready commands; specific examples cover the common cases'.

Workflow Clarity

The commands include an explicit validation checkpoint ("assert exit 0") and a failure feedback loop ("re-run the failing spec alone and inspect the screenshot/video artifacts", upload in CI "only on failure"). However, the run/debug workflow is compressed into prose rather than explicit ordered steps — anchor 4's 'clear sequence with most checkpoints present, minor gaps' fits better than 5's fully spelled-out validate/fix/retry sequence.

Progressive Disclosure

The body is under 50 lines with no bundle files needed (no references/, scripts/, or assets/ exist) and is cleanly organized into Layout, Gotchas, and Commands sections with pointers to the project test config. Per the simple-skill guideline, well-organized sections alone earn anchor 5.

Specificity

Names the domain and several concrete capabilities ("cy.intercept(), cy.session(), custom commands and CI artifacts"), but these are noun-topics rather than stated actions, with minor coverage gaps (e.g., fixtures, selectors). Fits anchor 4 — several specific items with minor gaps — better than 5's comprehensive action coverage or 3's 1-2 concrete actions.

Completeness

Explicitly answers both: the "what" ("Cypress E2E and component tests: cy.intercept(), cy.session(), custom commands and CI artifacts") and a concrete explicit "when" ("Use when writing or debugging Cypress specs, or running Cypress in CI"). Clear anchor-5 match with concrete trigger phrases; not 4 because the 'when' clause is explicit and specific rather than improvable.

Trigger Term Quality

Includes natural phrases users would say — "writing or debugging Cypress specs", "running Cypress in CI", "E2E", "component tests" — but misses common synonyms and variations like "end-to-end" spelled out, ".cy.ts" file extensions, or "fixtures". Anchor 4's 'good keyword coverage, a few natural terms missing' is the best fit; not 5 since extensions/synonyms are absent.

Distinctiveness Conflict Risk

The distinctive tool name "Cypress" appears in every trigger phrase, creating a clear niche with minimal conflict risk — a user mentioning Cypress unambiguously wants this skill and no other. Only negligible overlap with generic CI or component-testing skills; fits anchor 5 better than 4's 'minor overlap risk'.
