Junie now uses your IDE's actual debugger, build system, and test runners instead of approximating them—reducing token waste by planning before coding.
Summary
Agents that understand project context and run asynchronously shift from novelty to delegation tool. Plan-first workflow cuts failed implementations and review cycles; debugger integration replaces println-based troubleshooting with real runtime inspection.
Why it matters
Agents that understand project context and run asynchronously shift from novelty to delegation tool. Plan-first workflow cuts failed implementations and review cycles; debugger integration replaces println-based troubleshooting with real runtime inspection.
Implementation verdict
Replaces manual agent prompting workflows and ad-hoc debugging. Requires JetBrains IDE + AI subscription or BYOK (Anthropic/OpenAI/Google). Ready now—GA release with ACP protocol integration across all JetBrains IDEs and CLI. Worth trying immediately if you're in the JetBrains ecosystem and have token budget for reasoning models on planning tasks.
