Single tool with strong naming (verb_noun: resolve_reference), excellent description (194 chars, LLM-optimized), and proper schema with typed parameters. Tool annotations present (readOnlyHint, idempotentHint). Output schema documented in code but not formally exposed. Error handling returns structured JSON with guidance ('Do not fabricate'). Main gaps: output schema not formally declared in tool definition; no pagination/limit parameters despite potential for large result sets; parameter description could specify query length constraints.

• Add formal outputSchema to resolveReferenceToolDefinition documenting the structure: { matches: Array<{ref: {id, title, ...}, confidence}>, ambiguous: boolean, degraded?: boolean, note?: string }
• Specify query parameter constraints in description: 'A phrase or partial quote (1-500 chars). Accepts misspellings, colloquialisms, and partial matches.'
• Document result limits: 'Returns up to 10 matches ranked by confidence. If ambiguous (top 2 scores within 0.05), both are returned.'
• Add HTTP transport support (Streamable HTTP or SSE) to enable remote client access and hosted deployments.
• Consider adding optional limit parameter (default 10, max 50) to let callers control result set size for different use cases.

Inferred effective spec: 2026-07-28+.

• Relies on Stateful initialize / Mcp-Session-Id (removed; protocol is stateless) - make each request self-contained
