Production-Grade Prompt Engineering: Tests, Versioning, and Rollback

4 min read

Prompts are code. They deserve tests, versioning, and rollback. This is the framework we deploy at every AI engagement.

  1. 01Store prompts as version-controlled YAML

    Not strings in code; not Notion docs.

  2. 02Reference prompts by hash in production

    Every inference logs which prompt SHA produced it.

  3. 03Test with a regression eval on every PR

    Curated 200-example benchmark; CI fails on regression.

  4. 04Canary new prompts at 10% before full rollout

    Identical to feature flag deployment patterns.

  5. 05Auto-rollback on output quality drop

    Statistical drift detection on output classes.
