| # Ottema StructFix Demo | |
| Repair broken JSON / tool-call output against a typed schema. Model: `ottema/structfix-codet5p-220m` (220M params, Apache-2.0). | |
| ## Use cases | |
| - LLM emits invalid JSON → fix it | |
| - Missing required fields → fill or flag | |
| - Wrong enum values → coerce to valid | |
| - Markdown-wrapped output → strip the wrapper | |
| - Partial / truncated JSON → complete it | |
| - Schema-constrained generation recovery | |
| ## How it works | |
| The user provides a DSL schema (typed fields with enums and required flags) and a broken output. The model returns a valid JSON object that matches the schema. | |
