Dropstone is an agentic IDE that goes beyond simple code completion. While standard editors guess the next token, Dropstone’s Horizon Mode orchestrates a recursive swarm of agents to explore, compile, and debug solutions in the background—decoupling deep reasoning from your immediate keystrokes.

Dropstone features Horizon Mode for architectural planning and Semantic Entropy Tracking for real-time hallucination defense. It provides infinite context retention and adaptive learning from natural language interactions. The system utilizes a D3 Engine for infinite context virtualization, recursive swarm architecture for agentic reasoning, and background autonomous refactoring. It includes Distributed Knowledge propagation, Dynamic Distillation, Context Promotion, and Associative Semantic Graphing capabilities.

The system works by deploying up to 10,000 isolated "Scout" agents utilizing optimized Small Language Models to explore low-probability solution vectors. When a Scout hits a dead end, it broadcasts a "Failure Vector" to prune invalid logic branches. Candidate solutions clearing the confidence threshold are promoted to Frontier Models for high-fidelity refinement. The system utilizes Semantic Entropy Tracking to monitor agent outputs and prune high-perplexity trajectories.

Benefits include replacing traditional IDEs with self-correcting intelligence, enabling enterprise-scale engineering with autonomous background swarm capabilities. It allows for 100x faster prototyping and reduces manual overhead to near zero. The system maintains 60fps UI responsiveness while solving complex problems.

Target users include software engineers working on enterprise engineering, legacy migration, and system design automation. The product integrates as a fully compatible fork of VS Code and utilizes technologies including Protocol Buffers, HNSW Vector indexing, and microVM sandboxing.
