  • The Hook: Most developers use GitLab Duo as an autocomplete tool. But upstream in the ai-assist repository, GitLab has built an extensible Python/FastAPI AI Gateway orchestrating autonomous multi-step agent workflows.
  • Key Concepts Covered:
    • Anatomy of the GitLab AI Gateway (modelops/applied-ml/code-suggestions/ai-assist).
    • Authoring deterministic tool definitions with Pydantic v2 schemas.
    • Mitigating agent runaway loops with tool-call idempotency guards.
    • End-to-end testing with pytest-asyncio and mock LLM responses.

  • The Hook: As monorepos scale, CI minutes explode and feedback loops stretch from 5 minutes to 1 hour. How does GitLab keep internal pipelines efficient across thousands of daily commits?
  • Key Concepts Covered:
    • rules:changes pitfalls and git history depth gotchas.
    • Dynamic child pipelines: generating .gitlab-ci.yml jobs programmatically at runtime using build matrix scripts.

  • Key Concepts Covered:
    • Generating CycloneDX SBOMs natively in GitLab CI using open-source scanners.
    • Cryptographic container signing using Sigstore Cosign without long-lived private keys (Keyless OIDC).
    • Enforcing signature verification in production before deployment.
    • Publishing SBOMs directly to GitLab Dependency List and Vulnerability Report.
  • Why It Gets Approved (200 Pts): Highlights GitLab Ultimate/Premium DevSecOps capabilities and OIDC federation.
