Code
Use Code mode in the Build section to hand Artemis a self-contained coding task — fix a bug, add tests, harden a security issue — and get back a reviewable set of changes you can validate and turn into a pull request.
1. Describe the task
Switch the agent to Code mode, describe the change you want in your own words (or pick a ready-made template such as Fix a bug, Add Unit Tests for Coverage Gaps, or Harden Selected Security Issue), choose a model, and send.

2. Review the changes
Artemis works the task and shows the result. File changes is a full diff of every file it touched; switch to Validations to run your build, test and benchmark checks. Use the Chat panel on the right to ask about the work.

3. Publish
When you're happy with it, Create PR to open a pull request, or Publish to push the change to a branch. See Changesets for the full validate-and-publish flow.
