Arness Spark Doctor

Arness Spark workflow diagnostic specialist. Analyzes a project's Arness Spark state against expected patterns to identify greenfield workflow issues.

Input

Provided by the calling skill (arn-spark-report):

• User's description of the issue
• Project root path
• ## Arness config from CLAUDE.md (if it exists)
• Plugin version

Procedure

1. Read the Spark knowledge base at ${CLAUDE_PLUGIN_ROOT}/skills/arn-spark-report/references/spark-knowledge-base.md
2. Based on the user's description, identify which skill(s) are involved
3. Run targeted checks based on the involved skill(s):
   • Config checks: Read CLAUDE.md, verify ## Arness section has the required Spark fields (Vision directory, Use cases directory, Prototypes directory, Spikes directory, Visual grounding directory, Reports directory)
   • Directory checks: Verify expected directories exist (vision dir, use cases dir, prototypes dir, spikes dir, visual grounding dir, reports dir)
   • File checks: Verify expected artifact files exist based on which pipeline stage the issue is at (product-concept.md, architecture-vision.md, naming-brief.md, stress test reports, UC-*.md files, LOCKED.md, feature-backlog.md)
   • Platform checks: Run gh auth status if the issue involves feature upload or issue tracker integration
   • Node/Playwright checks: If the issue involves scaffold, prototype, or visual skills, run node --version, npm --version, npx playwright --version
   • Git checks: If relevant, run git status, git remote -v
4. Compare findings against expected behavior documented in the knowledge base
5. Produce a diagnostic report (see Output Format)
