The server defines 4 tools with explicit schemas and descriptions visible in src/mcp_server.py. Tool names use action verbs (recall, store, list, flag) which is good naming practice. However, descriptions are inconsistent in depth, recall_memory and store_memory have detailed, context-aware descriptions (120-180 chars), while list_recent_memories and flag_contradiction are shorter and less prescriptive (40-80 chars). All tools have input schemas with typed parameters and defaults, but output schemas are not formally documented, responses are unstructured strings rather than typed objects. Error handling exists but is minimal: catch-all Exception blocks return generic error messages without recovery guidance. Parameter descriptions are present but inconsistent, some lack detail about format or constraints. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear read/write semantics. This is typical mid-tier community work: functional but not production-grade.

• Add formal output schemas. Define recall_memory to return {memories: [{id: int, type: string, module: string, date: string, confidence: float, content: string, file_paths: string[], status: string}], total: int} instead of unstructured text. Use the same format for all tools.
• Add tool annotations in FastMCP registration. Use readOnlyHint=true for recall_memory and list_recent_memories; destructiveHint=true for store_memory and flag_contradiction. Example: @mcp.tool(readOnlyHint=true) for reads.
• Enhance error messages with recovery guidance. Instead of 'Failed to store memory: {e}', return 'Failed to store memory: duplicate content hash. Call list_recent_memories(module=...) to review existing records.' or 'Invalid memory_type. Allowed: episodic, semantic, procedural.'
• Add enum constraint to memory_type parameter in store_memory schema. Replace string type with enum: ['episodic', 'semantic', 'procedural'].
• Document pagination behavior. Add to recall_memory and list_recent_memories descriptions: 'Results are limited to prevent token exhaustion. Use limit parameter (1-100, default 5/10). No pagination cursor yet; re-call with modified query for next page.'
• Add idempotency note to store_memory description. Append: 'This tool is idempotent, repeated calls with the same content will return the same memory ID without duplication.'
• Set explicit bounds on numeric parameters. limit parameter in both tools should have min=1, max=100 in schema and mentioned in description.
• Validate memory_id in flag_contradiction. Currently accepts any integer; should ensure it is within reasonable bounds (e.g., > 0) and return 'Invalid memory_id format' before query attempt.
