The outcome

Learn the interaction loop using a small task with a clear outcome.

Junie is a JetBrains coding agent for IDE, terminal, and automated review workflows. Exploring a codebase, producing an implementation plan, making supervised changes, and reviewing local or pull-request diffs with durable project guidance. This guide narrows that broad capability into one repeatable outcome, with checkpoints that keep the source material and your judgment in the loop.

Before you begin

Set the boundary before the tool starts.

Choose one real task, identify who will use the result, and decide what evidence or test will make the result acceptable. Gather only the source material needed for that task. If the work contains confidential, personal, regulated, or client-owned information, confirm that the platform and account are approved before sharing it.

Troiana principle

AI should make the work easier to inspect. If the workflow removes the source, the owner, or the review step, redesign the workflow.

Step by step

A workflow you can repeat.

  1. 01

    Open a clean Git branch, keep an unfamiliar project untrusted until its configuration is reviewed, and record baseline checks.

  2. 02

    Start in ask or plan mode and give Junie the outcome, acceptance criteria, relevant paths, constraints, and non-goals.

  3. 03

    Review the proposed plan, keep Brave mode off, and approve only the exact commands, MCP tools, and external paths required.

  4. 04

    Inspect every changed file, run trusted tests, use local review for a second pass, and release only through normal peer review.

Working standard

What good use looks like.

  • State the outcome before the background.
  • Provide the real source material.
  • Review the result before expanding the task.

Junie can edit files, run terminal commands, invoke MCP tools, read or write outside a project, load project configuration, and operate headlessly. Brave mode removes approval gates; broad regular expressions and action-type rules can authorize much more than intended; build-script edits may execute code. Review project trust, `.junie` configuration, `.aiignore`, guidelines, hooks, credentials, provider terms, and every allowlist rule before consequential work.
