Download the full job artifacts archive as base64 content.
AI agents call gitlab_download_job_artifacts to retrieve information from Gitlab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves/downloads existing job artifacts in base64 format. This is a read-only operation that queries and fetches data without side effects. While artifacts may contain sensitive information depending on the CI/CD pipeline, the tool itself performs no destructive, write, or execute operations. The severity is low because downloading artifacts does not modify state or trigger external operations.
From the tool's definition Tool name and description: 'Download the full job artifacts archive as base64 content' — download is a retrieval operation with no modification or deletion of data.
