Non-trivial changes start with the repository-local OpenSpec skills configured for Antigravity:
openspec-explore: Enter explore mode to think through ideas or investigate issues.openspec-propose: Propose a new change and generate planning artifacts.openspec-apply-change: Guide the implementation of a change.openspec-verify-change: Run verification and gather evidence.openspec-archive-change: Archive a completed change and update main specs.
BrandyFly is not yet suitable for navigation or flight safety decisions. Airspace and map data can be incomplete or outdated. Pilots remain responsible for using current official information and appropriate certified equipment.
Source code is available under the MIT License. Map, airspace, elevation, weather, and flight datasets retain their own licenses and attribution requirements; see Third-party data.
