Critical failures across all dimensions. The single tool 'search_vault' is explicitly DISABLED as of 2025-10-06 per its own description ('DISABLED as MCP tool'). No active, functional tools are exposed. Input schema is present (query, n_results, collection) but the tool itself is non-operational. Description acknowledges redundancy and replacement by 'auto_search_vault router'. Source code excerpt is incomplete (truncated mid-function), preventing full assessment of implementation quality. No evidence of parameter descriptions, error handling, or output schema documentation in visible code.

• Remove the disabled search_vault tool entirely or re-enable it with full documentation. A disabled tool in the schema confuses clients and wastes schema space.
• If auto_search_vault router is the replacement, expose it as an MCP tool with complete schema: input parameters (query, n_results, collection) each with descriptions, type constraints, and valid ranges.
• Document the output schema explicitly. E.g., 'Returns array of {id, content, metadata, score} objects, sorted by relevance score descending, capped at n_results.'
• Add parameter descriptions: 'query (string, required): Semantic search text (1-500 chars). n_results (integer, default 5): Number of results to return (1-100). collection (string, default obsidian_vault_mxbai): ChromaDB collection name.'
• Implement error handling with recovery guidance. E.g., 'Collection not found. Available collections: [list]. Try search_vault with a valid collection name.' instead of raw errors.

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
