accessibility-retest

--- name: accessibility-retest description: Verify accessibility fixes against the original issues, check for regressions, and write a WCAG conformance statement with remaining gaps. Use when fixes from an accessibility audit are in and the user wants them confirmed or a conformance statement. Not for a design-stage check or feedback on one component; see /accessibility-checklist, /design-a11y-audit or /coaching-a11y. metadata: argument-hint: "[project] [--skip-checks]" workflow: accessibility phase: 5 artifact: 05-retest.md --- # Retest Verify that accessibility fixes for "$ARGUMENTS" are effective and produce a formal conformance statement. **Arguments.** `$ARGUMENTS` may contain the project name and optional flags. Take the first token as `<project>` and treat `--skip-checks` as a flag; never include flags in file paths. All paths below use `<project>`. If `--skip-checks` is present, skip the prerequisite check and, **before writing any artifact**, append one line to `.singularskills/log.jsonl`: `{"ts":"<ISO timestamp>","skill":"accessibility-retest","workflow":"accessibility","phase":5,"project":"<project>","event":"skipped","artifact":"05-retest.md","note":"<reason or \"none given\">"}`. ## Prerequisites **Part of a workflow.** This skill is phase 5 (Retest) of the WCAG-EM workflow (`accessibility`); cross-domain workflows run it too. First check `.singularskills/log.jsonl` for an open run for this project: a `run-started` line with `"project":"<project>"` and no later `run-finished` line for the same `workflow` and `project`. If one exists, the conductor is running you: continue here. Otherwise, if the user asked to start, run, continue or resume a process or workflow rather than this one step, do not continue here: invoke the `workflow` skill with the workflow the user asked for, or `accessibility` when they named none, followed by `<project>`; it runs this phase in order, asks before it writes and records the run. Otherwise continue here: a later phase runs on its own, behind its gate. Run this skill's gate before writing: `sh <this skill's folder>/scripts/gate.sh <project> <project root>`, where `<project root>` is the folder that contains `.singularskills/` (use `.` when you are already there). If it exits non-zero, stop and tell the user what it printed, unless `--skip-checks` was given (see Arguments). On a refusal, before you stop, append this line to `.singularskills/log.jsonl` (create the folder and file if missing): `{"ts":"<ISO timestamp>","skill":"accessibility-retest","workflow":"accessibility","phase":5,"project":"<project>","event":"refused","artifact":"05-retest.md","note":"<what the gate printed>"}`. Once the gate has passed, or under `--skip-checks` once you have appended the `skipped` line, append this line before you start work: `{"ts":"<ISO timestamp>","skill":"accessibility-retest","workflow":"accessibility","phase":5,"project":"<project>","event":"started","artifact":"05-retest.md","note":""}`. Read all prior artifacts. If `.singularskills/accessibility/<project>/04-remediate.md` does not exist, tell the user: > Phase 4 (Remediate) has not been completed for "<project>". Run `/accessibility-remediate <project>` first, or use `--skip-checks` to bypass. ## Process 1. **Read all prior artifacts:** - Read `.singularskills/accessibility/<project>/01-scope.md` for original scope - Read `.singularskills/accessibility/<project>/02-evaluate.md` for original issues - Read `.singularskills/accessibility/<project>/03-report.md` for detailed findings - Read `.singularskills/accessibility/<project>/04-remediate.md` for fixes applied 2. **Re-evaluate each fixed issue:** - Read the current code for each fixed issue - Verify the fix resolves the original WCAG violation - Check for regressions — did the fix break anything else? - Update issue status: verified fixed, partially fixed, or regression found 3. **Run regression checks:** - Re-check all WCAG criteria from the scope - Verify no new issues were introduced by the fixes - Check keyboard navigation flow end-to-end - Verify ARIA attributes are correct 4. **Produce conformance statement:** - Overall conformance level achieved - Per-principle conformance status - Known remaining issues (if any) - Recommendations for ongoing maintenance 5. **Write the artifact** to `.singularskills/accessibility/<project>/05-retest.md` with sections: - **Verification Results** — each issue with retest outcome - **Regression Check** — any new issues found - **Conformance Statement** — formal WCAG conformance declaration - **Remaining Issues** — known gaps with justification - **Maintenance Recommendations** — ongoing monitoring advice ## Output The conformance statement written to `.singularskills/accessibility/<project>/05-retest.md`. Present a summary to the user highlighting: - Conformance level achieved - Issues verified as fixed - Any remaining gaps - Maintenance recommendations **Record the run.** After you have written the artifact, append this line to `.singularskills/log.jsonl` (the `started` line of Prerequisites, with `"event":"finished"`): `{"ts":"<ISO timestamp>","skill":"accessibility-retest","workflow":"accessibility","phase":5,"project":"<project>","event":"finished","artifact":"05-retest.md","note":""}`. Open the artifact with this frontmatter (`agent` is the agent you run in, or `unknown`; `gate` is `passed` when the gate ran clean and `skipped` under `--skip-checks`): ```yaml --- skill: accessibility-retest workflow: accessibility phase: 5 project: <project> started: <ISO timestamp> finished: <ISO timestamp> agent: <the agent you run in, or "unknown"> gate: <passed|skipped> --- ``` End the artifact with `## Decisions` and `## Open questions`, in this shape: ```markdown ## Decisions - <what was chosen> — <why> — <what was rejected> ## Open questions - <what the next phase or a reviewer must settle> ```
