JetBrains Context: Repository Intelligence for Coding Agents
Summary
JetBrains Context adds repository intelligence to coding agents by incrementally indexing code and retrieving relevant implementation knowledge. JetBrains reports lower agent effort, latency, and execution cost across open-source, production-monorepo, and code-localization evaluations, though the excerpt does not provide baseline details or independent validation.
Problem
- Coding agents often spend substantial time searching repositories, reading files, and launching exploratory agents before they can implement or review changes.
- Limited visibility into APIs, dependencies, implementation patterns, and organization-wide code makes agents less effective on large codebases and can increase review, rework, and token costs.
Approach
- JetBrains Context incrementally builds a semantic index of each repository and exposes semantic retrieval tools so agents can query concepts and related code instead of relying only on keyword search and repeated file exploration.
- Its multi-repository search lets agents find relevant code, APIs, dependencies, and implementation examples in repositories that are not checked out locally.
- The layer integrates with Claude Code, Codex CLI, and Junie CLI, and is accessible through JetBrains IDEs, Air, VS Code, and other supported editors.
- Agent hooks can automatically pre-index source code; JetBrains states that source code is not stored on its servers.
Results
- JetBrains evaluated the system on 205 open-source SWE-bench tasks, 175 production-monorepo tasks, and 1,953 code-localization tasks.
- Across these evaluations, JetBrains reports reductions of up to 68% in agent turns, 59% in latency, and 48% in execution cost.
- The reported figures are maximum reductions rather than averages, and the excerpt does not identify the comparison baseline, task-level success changes, or independent evaluation results.
- JetBrains offers the capability in early access at no additional cost for subscribers to its JetBrains AI for Teams and Organizations plans.
