The server has 7 tools with explicit registration, complete input schemas using Zod, and clear descriptions. However, there are significant gaps: most parameter descriptions are minimal (averaging ~30-50 chars vs. the 72-char baseline), many optional parameters lack explanation of when to use them, output schemas are NOT documented (only inferred from code), and error handling is generic without recovery guidance. Tool names follow verb_noun convention (save_decision, query_memory, list_recent, update_decision, get_stats, sync_claude_md, review_session) and are reasonably descriptive. The server demonstrates awareness of composition patterns (separate read vs. write tools) and addresses a genuine problem domain (persistent decision memory). But compared to production baselines, the implementation lacks depth in parameter guidance, output documentation, and error classification.

• Document the output schema for each tool. For save_decision, explicitly define: { id: number, title: string, autoSuperseded?: number[], similarDecisions?: { id, title, similarity }[] }. For query_memory, document { results: [{ id, title, decision, rationale, alternatives?, consequences?, affected_files?, created_at }], query: string }. This enables LLMs to reliably extract and chain results.
• Expand parameter descriptions to 50 - 100 chars with concrete guidance. Example: change 'alternatives' in save_decision from 'What else was considered' to 'Alternative approaches considered and rejected (e.g., ["OAuth2", "Session tokens"]). Optional but recommended for context.'
• Classify and guide errors. In error handlers, return structured responses like { success: false, error: 'no_results', message: 'No decisions match your query.', suggestion: 'Try a simpler query, check session filters with list_recent(), or use save_decision() to create a new decision.' }. This helps LLMs self-correct.
• Add idempotency notes to save_decision and update_decision. Document: 'Calling save_decision twice with identical args will create separate records (not idempotent). Use update_decision to modify an existing decision. Re-running update_decision with the same status and notes is safe.'
• Set explicit max limits for result tools. Change query_memory and list_recent descriptions to include: 'Results are capped at limit (default 5 for query_memory, 10 for list_recent; max 50). Use pagination offsets for additional results.' Implement offset/limit or cursor-based pagination if result sets are large.
