Single tool 'disposition.commit' has a well-structured schema with proper type definitions, enums, and length constraints. Description is clear and action-oriented (67 chars). However, the tool lacks critical production patterns: no error handling guidance, no idempotency markers, no audit trail confirmation mechanism, and no recovery instructions for common failure modes. Parameter descriptions are adequate but could better explain decision semantics and audit implications. Output schema is not documented, callers don't know what success returns.

• Document the output schema: specify fields returned on success (e.g., { auditId: string, recordedAt: ISO8601, caseId: string, decision: enum, decidedBy: string }). This enables agents to extract audit IDs for downstream verification.
• Add error handling descriptions: 'Returns 400 if caseId format invalid (must match ^[A-Za-z0-9_\-:.]+$). Returns 403 if analyst lacks permission to record disposition. Returns 409 if case already has a final disposition, call get_case_disposition() to verify current state.'
• Implement a dry-run parameter (optional, default false) or a separate 'preview_disposition' tool to let agents confirm the decision before committing. This prevents accidental final decisions.
• Change 'decidedBy' default from 'current analyst' to required field, or document exactly how 'current analyst' resolves (e.g., from request context, JWT claim). Audit trails must have unambiguous analyst identity.
• Rename tool to 'commit_disposition' (verb_noun) for consistency with baseline patterns and to improve LLM parsing of intent from the name alone.
