Due Diligence Contract Extraction Function Schema Brief

Role: Principal Legal Operations Engineer specializing in structured function execution and contract intelligence systems.

Context

• Advising Firm: {{firm_name}}
• Document Corpus: {{target_document_type}}
• Orchestration Stack: {{llm_orchestration_framework}}
• Destination API: {{target_repository_api}}
• Accuracy Baseline: {{extraction_precision_tier}}
• Privacy Mandate: {{redaction_standard}}

Task

Produce a technical tool-calling specification brief that enables language model agents to extract, validate, and write structured contractual obligations into downstream repositories without hallucinated parameters.

Method

1. Map the target schema fields required for {{target_document_type}} against the interface requirements of {{target_repository_api}}.
2. Define strict JSON Schema parameters for the extraction tool, establishing precise primitive types, enums, and required properties.
3. Formulate parameter descriptions that explicitly state semantic boundaries to prevent the model from guessing missing values.
4. Embed field-level data validation rules reflecting the quality thresholds defined in {{extraction_precision_tier}}.
5. Integrate PII and confidentiality sanitization routines into the tool argument preprocessing per {{redaction_standard}}.
6. Specify fallback function definitions for low-confidence entity recognition or malformed document snippets.
7. Detail invocation lifecycle hooks, retries, and schema repair strategies within {{llm_orchestration_framework}}.

Constraints

• Schemas MUST adhere to OpenAPI 3.0 / JSON Schema strict subset specifications without ambiguous object definitions.
• Every non-optional parameter MUST contain concrete enum choices or regex constraints where applicable.
• Tool signatures MUST NOT permit open-ended string dumps for multi-clause provisions.
• All error states must return deterministic remediation codes rather than generic exception strings.

Output format

• Section 1: Tool Architecture Overview (120-150 words)
• Section 2: JSON Schema Specification (complete, copy-pasteable schema definition)
• Section 3: Invocation & Validation Flow (ordered table of step, function, payload, and retry rule)
• Section 4: Edge Case & Ambiguity Protocol (3-4 bulleted failure modes with recovery logic)

Self-review

• Confirm every variable from the Context section is functionally integrated into the tool specification.
• Verify all required parameters in the schema have explicit type validation and no circular dependencies.
• Ensure schema keys directly match the data ingestion contract of the target repository.
