Task Completion Verification Skill

What it does

• Confirms acceptance criteria are met with evidence.
• Checks quality gates (tests, QA, accessibility/performance where relevant).
• Ensures documentation and stakeholders are updated before closure.

When to use

• Before demo/release to ensure readiness.
• When handing off to QA/UAT or stakeholders.

Key operations

• Identify active project and task; review acceptance criteria and task state (tasks/*.json).
• Verify implementation against criteria; capture evidence (screenshots, logs, links).
• Validate tests (unit/integration/e2e) and linters; check performance/a11y/security as applicable.
• Update docs/changelog/release notes; confirm stakeholder sign-off or UAT.
• Move task state to testing/done per AGENTS.md, log results and time, update memory/YYYY-MM-DD.md.

Output files

• projects/<ACTIVE>/tasks/in-progress.json → tasks/done.json (state transition when complete).
• projects/<ACTIVE>/tasks/task-log.md — evidence, test results, time spent, blockers resolved.
• projects/<ACTIVE>/verification/checklist.md — criteria, evidence, test results, sign-offs (if repo uses verification/).
• projects/<ACTIVE>/verification/test-results.md — summary of automated/manual test outcomes.
• projects/<ACTIVE>/verification/release-notes.md — user-facing changes and impacts (if shipping).
• memory/YYYY-MM-DD.md — decisions, sign-offs, risks.

Example workflow

1. Identify active project and task.
2. Re-read acceptance criteria; walk through implementation against each with evidence.
3. Run automated tests; execute targeted manual checks (a11y/perf/security if needed); record in test-results.md/task-log.md.
4. Update checklist.md and release-notes.md; obtain sign-off (QA/PO); move task to done.json; log in memory/YYYY-MM-DD.md.

Best practices

• Evidence-first: link PRs, screenshots, logs for each criterion.
• Do not skip tests; rerun after late changes; note flaky cases.
• Include a11y/perf spot checks for UI; include security considerations for APIs.
• Keep checklists short, consistent, and repeatable.
• Update task state immediately after verification; keep audit trail in task-log.md and memory/YYYY-MM-DD.md.
• Avoid deleting/overwriting artifacts; follow AGENTS.md safety (no destructive operations).
