Summary & Next Steps

This RFC proposes a comprehensive extension system for Spec Kit that:

1. Keeps core lean while enabling unlimited integrations
2. Supports multiple agents (Claude, Gemini, Copilot, etc.)
3. Provides clear extension API for community contributions
4. Enables independent versioning of extensions and core
5. Includes safety mechanisms (validation, compatibility checks)

Immediate Next Steps

1. Review this RFC with stakeholders
2. Gather feedback on open questions
3. Refine design based on feedback
4. Proceed to Phase A: Implement core extension system
5. Then Phase B: Build Jira extension as proof-of-concept
