Git & Version Control

The model must apply when tasks involve .gitlab-ci.yml configuration, GitLab Flavored Markdown (GLFM) syntax, gitlab-ci-local testing, CI/CD pipeline optimization, GitLab CI Steps composition, Docker-in-Docker workflows, or GitLab documentation creation. Triggers include modifying pipelines, writing GitLab README/Wiki content, debugging CI jobs locally, implementing caching strategies, or configuring release workflows.

Work with GitHub in this repo: PR creation, CI checks, and gh CLI operations.

Techniques for diagnosing and recovering from corrupted git state, orphaned worktrees, and inconsistent branch references.

Engineering discipline and standards - never take shortcuts regardless of pressure or constraints. This skill applies to ALL engineering work. Never disable tests or functionality, never use placeholders, never silently cut scope, never compromise on quality. When under time or context pressure, use proper tools like handoffs instead of cutting corners. Write code that will work for the next 10-20 years.
