testland/a11y-violation-gate

Builds a CI gate that fails the build on **new** WCAG / a11y violations introduced by a PR while grandfathering pre-existing violations on a per-rule / per-page baseline. Aggregates verdicts from axe-core / pa11y / Lighthouse a11y / WAVE / IBM Equal Access scans. Use when a project has accumulated a11y debt and a strict \"zero violations\" gate would block every PR - the ratchet pattern lets the team ship while preventing regressions.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-organized, actionable skill body with a clear multi-step workflow, an executable reference implementation, and clean progressive disclosure into one reference file. Minor gains available from tightening framing prose and making the post-fix verification checkpoint explicit.

DimensionReasoningScore

Conciseness

Mostly lean and efficient — it never explains concepts Claude already knows (what WCAG/axe/CI gates are) and every section is functional — but a few framing sentences ('The shrinking baseline counter is the positive signal...') and the Overview problem-setting could be trimmed slightly.

4 / 5

Actionability

Provides a fully executable, copy-paste-ready Python gate script for axe-core plus concrete JSON record and baseline shapes; the other four scanners are specified via field mappings in the reference rather than as copy-paste code, leaving a minor gap.

4 / 5

Workflow Clarity

Clear five-step sequence with a gate-decision checkpoint, an explicit feedback loop in Step 5 (PR fails → fix or debate → regenerate baseline), and an anti-patterns checklist, but post-fix re-verification and the quarterly review are soft rather than hard checkpoints.

4 / 5

Progressive Disclosure

Well-structured overview with scanner shapes and the full PR artifact template moved to a single one-level-deep reference (references/gate-implementation.md), referenced inline with context and easy to navigate.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that clearly states concrete capabilities, names the tools it aggregates, and gives an explicit 'Use when' trigger tied to a real-world pain point. No fluff or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Builds a CI gate that fails the build on new WCAG / a11y violations', 'grandfathering pre-existing violations on a per-rule / per-page baseline', and 'Aggregates verdicts from axe-core / pa11y / Lighthouse a11y / WAVE / IBM Equal Access scans' — giving comprehensive coverage of what it does.

5 / 5

Completeness

Explicitly answers both 'what' ('Builds a CI gate... Aggregates verdicts from...') and 'when' via a concrete 'Use when a project has accumulated a11y debt and a strict zero violations gate would block every PR' trigger clause.

5 / 5

Trigger Term Quality

Covers the natural terms users would say — 'WCAG', 'a11y', 'a11y debt', 'CI gate', 'zero violations gate', 'ratchet pattern', plus all five scanner names — with synonyms (a11y/WCAG) well represented.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (a11y ratchet/baseline gate for CI) with highly specific trigger conditions and named scanners, making conflict with other skills minimal.
