# Auto-generated 50-Prompt Battery > [!summary] > The auto-generated 50-prompt test is for broad coverage and regression detection. It is separate from the Controlled Batch Runner. --- ## What it is The auto-generated launcher generates a full 50-prompt session through Lucia and sends the responses into the same Review Queue used by Custom runs. Canonical route: ```text /lucia/auto-generated ``` Legacy alias: ```text /lucia/automated ``` --- ## When to use it Use the auto-generated 50-prompt battery when: - a broader Engine change has landed - a model or prompt change may affect multiple behavior families - an owner/admin validation pass is needed - an evaluator assignment needs broader generated coverage - a tester cohort needs prompt-testing signal beyond a custom suite - you want broad confidence after targeted custom-suite refinement This surface is available to owner/admin, evaluator, and tester roles in the current access model. --- ## When not to use it Do not use the 50-prompt battery when trying to isolate one behavior bug. Use a custom suite first. The auto-generated battery is a net, not a scalpel. Do not use it as the controlled platform-readiness gate. Use [[04 - Controlled Batch Runner Protocol|Controlled Batch Runner Protocol]] for that. --- ## Review strategy When reviewing a 50-prompt run: 1. Review obvious failures first. 2. Look for repeated patterns. 3. Do not over-focus on one strange answer. 4. Export after completing enough reviews to support a product decision. 5. Create a custom suite from repeated failure patterns. --- ## Relationship to Custom suites A strong workflow often looks like this: ```text Auto-generated 50-prompt run finds pattern → reviewer creates targeted custom suite → engineer patches Lucia → custom suite confirms fix → auto-generated run checks neighboring regressions ``` --- ## Relationship to controlled batches The auto-generated tester and Controlled Batch Runner both exercise 50-prompt run infrastructure, but they serve different product jobs. ```text Auto-generated tester = normal broad regression surface. Controlled Batch Runner = controlled platform-readiness protocol. ``` AI-reviewed controlled batch results prove the platform lifecycle. Human review still owns Lucia quality judgment. --- ## Auto-generated 50-prompt suite in Eval Labs >![[automated-50-prompt-launcher.png]] _Use this for broader regression coverage._ --- >![[automated-50-prompt-launcher-with-saved-runs.png]] _Custom prompt suite loaded and ready for analysis in Evaluation Labs._
