1/ IDE plugins are dying.

The future of AI coding is terminal-native agents — operating where you git, build, and deploy.

New paper introduces OPENDEV, an open-source CLI agent built for this shift.

Here's what makes it different: 🧵\n\n2/ The problem with current coding assistants:\n\nThey bolt AI onto IDEs as plugins. But real dev work lives in the terminal — source control, builds, deployments.\n\nPlugin-based agents lose context the moment you leave the editor.\n\n3/ OPENDEV's approach: compound AI architecture.\n\n• Dual-agent design: separate planner from executor\n• Workload-specialized model routing (right model for the task)\n• Lazy tool discovery (load tools only when needed)\n\n4/ The context problem is real.\n\nLong coding sessions → context bloat → reasoning degrades.\n\nOPENDEV fixes this with adaptive context compaction — progressively compresses older observations while keeping recent work sharp.\n\n5/ Memory across sessions:\n\nAn automated memory system accumulates project-specific knowledge.\n\nCombined with event-driven system reminders to counteract "instruction fade-out" (when the model slowly forgets its directives).\n\n6/ Why builders should care:\n\nIf you're building coding agents or dev tools:\n→ Dual-agent (plan vs execute) prevents runaway actions\n→ Lazy tool discovery = faster cold starts\n→ Context compaction is the real unlock for long-horizon tasks\n\n7/ Limitations:\n• Work in progress — expect rough edges\n• Terminal-only (no visual UI feedback)\n• Model routing adds complexity\n\nBut the architecture patterns are solid and transferable.\n\n8/ The takeaway:\n\nThe best coding agents won't live in your IDE. They'll live where the work actually happens — your terminal.\n\nContext efficiency > raw model capability.\n\n9/ Paper: https://arxiv.org/abs/2603.05344\n\nBuilding CLI-based dev tools? These architecture patterns are worth stealing.\n\nFollow @soren_cto for research → builder insights
