Generated: 2026-02-21T14:20:00Z
Author: GitHub Copilot
Purpose: Comprehensive review of outstanding tasks in the alfa-scan project

Executive Summary

The alfa-scan project is an issue-driven accessibility scanning prototype using GitHub Pages, GitHub Actions, and Siteimprove's Alfa library. The project is organized into 6 work packages (WP01-WP06) with 30 subtasks total.

Current Status:

  • ✅ 1 work package complete (WP01 - 5 subtasks)
  • 📋 5 work packages pending (WP02-WP06 - 25 subtasks)
  • 🎯 Next steps: WP02 and WP03 can begin (both depend only on completed WP01)

Outstanding Work

WP02: GitHub Pages Intake and Issue Submission 📋

Status: PLANNED
Lane: planned
Priority: P1 (MVP)
Dependencies: WP01 ✅
Can Start: YES ✅

Subtasks (0/5):

  • T006: Build Pages form UI in pages/index.html and pages/submit.js
  • T007: Client-side normalization and max-100 validation
  • T008: GitHub-authenticated issue creation flow
  • T009: Client-side handling for malformed URLs
  • T010: Integration tests/fixtures for issue payload

Goal:

Provide a GitHub Pages form that accepts up to 100 URLs and creates structured authenticated issue requests.

Independent Test:

Authenticated user submits valid URL batch from Pages and correctly formatted scan issue is created.

WP03: Dual-Scanner Execution Engine 📋

Status: PLANNED
Lane: planned
Priority: P1
Dependencies: WP01 ✅
Can Start: YES ✅

Subtasks (0/6):

  • T011: Issue-event workflow entrypoint to parse request
  • T012: ALFA execution per URL with normalized status capture
  • T013: axe execution per URL with matching normalized status
  • T014: Per-URL fault isolation and continuation semantics
  • T015: Capture redirect information (submitted URL, final URL, redirected flag)
  • T016: Unit/integration tests for orchestrator behavior

Goal:

Process scan request issues and execute ALFA + axe for each valid target URL with resilient failure handling.

Independent Test:

Valid scan issue triggers workflow execution; both tools run for each target; failures on one URL do not halt remaining scans.

WP04: Public Reporting and Pages Publishing 📋

Status: PLANNED
Lane: planned
Priority: P2
Dependencies: WP03
Can Start: NO (blocked by WP03)

Subtasks (0/5):

  • T017: Comparison builder for per-URL and aggregate ALFA/axe deltas
  • T018: Generate machine-readable run artifacts and human-readable summaries
  • T019: Pages publishing workflow updates for report artifacts
  • T020: Maintain report index/history for discovering historical runs
  • T021: Validation tests for report schema and public link integrity

Goal:

Build report generation and publishing pipeline for public per-run ALFA vs axe comparison artifacts.

WP05: Security and Operational Hardening 📋

Status: PLANNED
Lane: planned
Priority: P2
Dependencies: WP03
Can Start: NO (blocked by WP03)

Subtasks (0/5):

  • T022: Authenticated submitter checks and scan-request eligibility rules
  • T023: Runtime public URL policy with explicit private/internal block reasons
  • T024: Abuse controls (concurrency keys, duplicate request handling)
  • T025: Harden workflow permissions and token scopes to least privilege
  • T026: Structured run diagnostics and issue status updates

Goal:

Enforce authenticated request controls, runtime safety checks, and observable operations.

WP06: End-to-End Verification and Release Readiness 📋

Status: PLANNED
Lane: planned
Priority: P3
Dependencies: WP02, WP04, WP05
Can Start: NO (blocked by WP02, WP04, WP05)

Subtasks (0/4):

  • T027: End-to-end scenario tests (form input → issue → workflow → report)
  • T028: Performance validation scenario for large batch (up to 100 URLs)
  • T029: Align documentation/runbook with quickstart and operational behavior
  • T030: Prepare demo dataset and acceptance verification checklist

Goal:

Validate full flow from Pages intake to public report publication and document operational runbook.

Notes

Task UUID Not Found

The original problem statement referenced task UUID 7f95899b-a262-4d03-a12d-89072861090e. This UUID was not found in the repository. This analysis was performed based on the task structure defined in kitty-specs/001-issue-driven-accessibility-scanner/tasks.md and the work package status in the tasks/ directory.

Spec Kitty Integration

This project uses Spec Kitty v0.10.8+ for project management. Work packages are organized in the kitty-specs/ directory with lane-based tracking (planned, doing, for_review, done).

Conclusion

The alfa-scan project has a solid foundation (WP01 complete) and a clear path forward. Two high-priority work packages (WP02 and WP03) are ready to start immediately and can be developed in parallel. The project follows good engineering practices with comprehensive testing, security controls, and clear documentation.

Estimated completion:

  • MVP (WP01-WP04 minimal): ~3-4 weeks
  • Full project (all WPs): ~6-8 weeks
