🚨 RISK MITIGATION

Risk 1: API Rate Limits

Mitigation:

  • Cache all API responses (24-hour TTL)
  • Implement request queuing
  • Use free-tier quotas strategically

Risk 2: Complexity Overwhelm

Mitigation:

  • Strict adherence to Spec-Kit SDD workflow
  • One feature at a time, fully tested
  • Weekly progress reviews

Risk 3: Data Quality Issues

Mitigation:

  • Validate all external API data
  • Unit tests for parsing logic
  • Manual spot checks during development

Risk 4: Scope Creep

Mitigation:

  • Constitution.md defines boundaries
  • "Nice-to-have" features deferred to v2.0+
  • Ruthless prioritization

🎯 NEXT STEPS (Tomorrow Evening!)

Your immediate actions:

  1. Read the Constitution (CELESTIAL_SIGNS_IMPLEMENTATION_PACKAGE.md)

  2. Run the 30-minute setup script (from Quick Start section)

  3. Complete Checkpoint 1A & 1B (Dev environment + structure)

  4. Open Copilot Chat and say:

    @github-copilot I'm ready to start the Celestial Signs project.
I've completed the environment setup. What should I implement first
according to the Week 1 plan in IMPLEMENTATION_TIMELINE.md?

  5. Use Spec-Kit for your first feature:

    /speckit.specify "Create the database schema and run initial migration"

You're not alone - Copilot (Claude 4.5) will guide you through every step!

Tomorrow evening at 7 PM, you begin building something extraordinary. 🌟
