Documentation AGENTS.md

The AGENTS.md file provides documentation instructions for GitLab Duo. When an agent writes documentation in the gitlab/doc directory, it reads AGENTS.md automatically and applies the instructions to its output.

Before you submit AI-generated content for review, ensure the following:

• Content is accurate.
• Common problems wth AI-generated content, like hallucinations and repetitive content, are addressed.

Use AGENTS.md

AGENTS.md is applied automatically at the start of each new GitLab Duo Chat conversation. You do not need to reference it in your prompt. To get the best results:

• Start a new chat conversation before beginning a documentation task.
• Make changes locally only. Do not commit or push AI-generated content before you have reviewed and iterated on the output.

Location

The AGENTS.md file is located in gitlab/doc/AGENTS.md. Because of the location, the instructions apply to documentation only. The instructions are not applied when contributors work on unrelated parts of the codebase.

Review AI-generated content

Before you request a review, check for the following known issues with AI-generated content:

• Repetition: Content that restates what has already be said on the page or in a linked topic.
• Vague or unverifiable claims: Descriptions of how a feature works that aren't grounded in the codebase or existing documentation.
• Incorrect scope: A new page has been created for a concept or procedure when a suitable page already exists. If you are unsure, Technical Writers can help identify a location in the documentation.
• Style guide adherence: Terms, grammar, and formatting that don't align with the style guide.

Update AGENTS.md

If you notice a recurring pattern in AI-generated content, open an MR to add or refine an instruction.

When you update the file, follow these principles:

• Keep instructions specific and actionable. Avoid vague guidance like Write concisely.
• Use examples when an instruction requires judgment. Instead of Avoid marketing language, provide an example: Avoid marketing language. For example, do not use "powerful" or "seamless".
• Test your changes. Start a new chat conversation and ensure the instruction is applied.
• If you update AGENTS.md, conversations must be restarted for changes to take effect. Existing conversations do not pick up changes automatically.
