Nova stores them server-side and pulls them in automatically when scoring. ## Criteria Lifecycle Create criteria via **AI generation** from a job description, or **manual creation** one at a time. ```mermaid theme={null} flowchart LR subgraph setup["AI Generation"] Q[Optional: Get Questions] --> A[Collect Answers] A --> G[Generate Criteria] end subgraph manual["Manual Creation"] M[Add Criterion] end subgraph library["Criteria Library"] LIB[("Tenant Library")] end subgraph manage["Management"] G --> STORED[Stored by Nova] M --> STORED LIB -->|add from library| STORED STORED --> VIEW[View Criteria] STORED --> ADD[Add More] STORED --> EDIT[Edit Criterion] STORED --> REMOVE[Remove Criterion] STORED --> ARCHIVE[Archive Criteria] ADD --> STORED EDIT --> STORED REMOVE --> STORED end subgraph scoring["Scoring"] STORED --> SCORE[Score Application] SCORE --> RESULT[Webhook with Score] end ``` ## Versioning Calling [Generate Criteria](/embed-api/endpoints/criteria/generate) for a job that already has criteria **replaces** the existing set. Historical scores keep the criteria version they were scored against. **Criterion IDs are stable.** Mutations create a new version, but each criterion keeps its original `id`. ## Importance Levels | Level | Impact on Scoring | Example | | -------------- | ------------------------------ | --------------------------- | | `MUST_HAVE` | Disqualifier if unmet | "Valid work authorization" | | `PREFERRED` | Significant concern if missing | "5+ years experience" | | `NICE_TO_HAVE` | Minor concern only | "Open source contributions" | ## Answer Validation | Check | Error Code | | ------------------------------------------------ | ------------------------ | | `questionSetId` required when `answers` provided | `VALIDATION_ERROR` | | Valid, existing question set | `QUESTION_SET_NOT_FOUND` | | Answer IDs match questions in the set | `ANSWER_MISMATCH` | | Answer types match question types | `ANSWER_MISMATCH` | If you include `answers`, answer every question in the set. ## Available Operations Create screening criteria from a job description Retrieve stored criteria for a job Retrieve active criteria with version metadata List historical criteria versions for a job Retrieve a specific historical criteria version Retrieve criteria for multiple jobs in one request Replace the entire criteria set for a job Add a single criterion to the job's criteria Update text or importance of a criterion Remove a single criterion from the job Archive criteria when a job closes ## Criteria Library Save common requirements once and reuse them across jobs. Store and reuse criteria across jobs ## Next Step Once you have criteria, you're ready to [Score Applications](/embed-api/endpoints/score).
