Collaboration and coordination system with file claims/leases, locking, conflict detection and merge readiness

Flockbay use cases

Automate iterative level design and polish by using LLM-driven agents to modify level geometry, lighting, foliage and object placement directly in-editor, run PIE playtests and smoke tests, and capture annotated screenshots for designer review and stakeholder sign-off
Automatically refactor, optimize and validate Blueprints across the project with Codex/Claude/Gemini suggesting and applying edits in-editor, running automated playtests and performance smoke tests, and producing change logs and reproducible screenshots for code review
Coordinate multi-agent QA and regression workflows that execute scenario-specific playtests, capture step-by-step screenshots and logs, triage failures into prioritized bug reports, and maintain shared project context so designers, QA and engineers can reproduce and fix issues faster
