Server has 9 tools with basic schemas and descriptions, but significant gaps limit production readiness. Tool names lack consistent verb-noun structure (e.g., 'verifyCredential' vs 'verify_credential'). Descriptions are present but generic (avg ~80 chars, below 194-char baseline). Parameter descriptions exist but lack constraint details (ranges, enums, formats). Tool #5 (auditBatch) has a 'verifyFn' parameter typed as 'function', not a valid JSON Schema type, making it unusable by LLM agents. Output schemas are not documented. Error handling returns structured VerificationResult but lacks recovery guidance. Security validation is strong (input sanitization, issuer checks), but tool composition has issues: setTrustedIssuer and resetTrustedIssuers are write operations without confirmation patterns, risking accidental state corruption.

• Rename all tools to snake_case verb_noun format: verifyCredential → verify_credential, resolveDID → resolve_did, etc. This matches LLM expectations and the 90% baseline of A+ tools.
• Fix auditBatch: replace 'verifyFn' function parameter with a 'verification_mode' enum (e.g., 'standard', 'merkle', 'batch') and handle verification internally. Functions cannot be passed via JSON.
• Document output schemas for all tools. Add a 'returns' section to each tool description listing field names, types, and meanings. E.g., verifyCredential returns {isValid: boolean, issuer?: string, data?: CredentialData, error?: string}.
• Add confirmation pattern to setTrustedIssuer and resetTrustedIssuers. Require a 'confirm' boolean parameter (default false) or implement a separate 'confirm_trusted_issuer_change' tool that must be called before the write succeeds.
• Enhance parameter descriptions with constraints: 'hashes: array of 1-10000 certificate hashes, each 64 hex characters (SHA-256). Example: ["abc123...", "def456..."]' instead of just 'Array of certificate hashes in hex format'.
