| What makes it different | - Preserves product context across tasks, agents, and code changes through a structured, verified product model
- Reduces handoffs and coordination by delegating whole features with connected specifications and implementation scope
- Prevents architecture drift by connecting implementation with subsystem architecture rules, unit guidelines, and component responsibilities
- Built for complex products where a single feature touches connected data, APIs, interfaces, and business rules across multiple repositories and systems
- Keeps product model current as specifications and implementation change using AI assistance and team review
| - 57.1% lower recorded model costs compared to vanilla Codex on benchmark runs
- Free and open source desktop app under Apache 2.0 license
- Agent routing included with Halv Cloud at no additional fee
- Single workspace for multiple AI coding models
- Matched vanilla Codex pass rates with lower cost
