dbt Schema-PR PII Pre-Merge Gate
When a GitHub pull request changes a dbt schema, inspects newly added columns for likely PII and posts a blocking review comment listing fields that need a sensitivity tag before…
How it runs
The automated pipeline, trigger to output.
- TriggerGitHub PR opened/updated on dbt schema filesGitHub
- LogicParse diff for newly added column definitions
- ActionClassify each new column for PIIOpenAI
- LogicDrop columns that already have a sensitivity tag
- OutputPost blocking PR review comment with flagged fieldsGitHub
What it does
Triggers on pull requests that touch dbt schema or model files, identifies columns being added in the diff, classifies each for PII, and posts an inline review comment flagging any sensitive column that lacks a `meta.sensitivity` tag so it gets handled before the data ever lands.
When to use it
Use it to shift PII governance left into code review, catching sensitive fields at the PR stage instead of discovering them in the warehouse weeks later.
How it works
- 1A GitHub pull-request webhook fires when schema or model YAML/SQL changes.
- 2Parse the diff to extract newly added column definitions and any existing meta tags.
- 3Classify each new column for PII type and confidence from its name and description.
- 4A filter drops columns that already carry a sensitivity tag.
- 5If any untagged PII remains, post a GitHub review comment listing each field and the suggested tag, marking the check as failing.
Set it up

- 4Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
- 5Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
