Workload & Production Scope Parameters

Define representative workload conditions to evaluate models realistically. Workload parameters provide descriptive prompt context without requiring database credentials or data uploads.

Descriptive workload context (informs prompt framing)
Descriptive codebase scope (informs prompt framing)
Analysis depth requirement (informs instruction framing)
Projection only (scales monthly business forecast)
Task Complexity: 1.0/10 (Simple) · 10,000 runs/mo projection

Workload parameters describe your production context to models transparently without connecting external databases.

One per line: exact:text, contains:text, json_valid, regex:^OK, length:10..500, or number:/score:0..10. Up to 10 checks. Use a JSON array for JSON Schema subset checks or multiline and whitespace-sensitive values. Check syntax and examples.

Optional scores for relevance, instruction following, clarity, safety flags, and alignment with your checks.

Masks model identities as "Model A", "Model B", etc., to eliminate bias during output grading.
