RepoPrompt is the uber AI dev productivity enhancer for devs and teams that deliver. A couple of features make it stand out: one is the Context Builder, which is the ability to precisely carve the context required by an LLM to execute a task optimally. The other is, via MCP, to enable multi-model collaboration within a single context window: you can have one model architect a solution, another challenge it, yet another offer a lateral take, all sharing the same codebase context and conversation history. The context selection system is surgically precise: codemaps give structural awareness without burning tokens, while you curate exactly which files get full attention. Running proposals through multiple models before touching code has caught architectural flaws that would've cost hours to unwind.
