fdl-worktree-create

To set up an isolated git worktree, you provide a GitLab issue or MR URL and the Skill creates a dedicated branch, links a Draft MR, and assigns a per-branch dbt-target state var. This prevents parallel investigations from overwriting each other's BigQuery target state.

You can reuse an existing linked MR branch only if it has zero commits ahead of origin/main. If the branch already contains changes, the workflow requires creating a new Draft MR instead to maintain a clean history.

A strict safety limitation is that the workflow refuses to run from inside an existing non-main worktree. You must execute the setup process from your main checkout to prevent nested branching conflicts and state corruption.

The workflow enforces upfront preparation by setting the per-branch dbt-target state var before switching into the created worktree. This ensures your BigQuery target configuration is fully mapped before any development begins.
