This evaluation is based on the tool definitions provided in the server metadata (6 tools declared). However, the actual source code provided is incomplete, it contains only Dockerfiles, Makefiles, and partial Go module declarations. The tool definitions themselves are sourced from metadata claims, NOT from verified source code inspection. Additionally, CRITICAL GAPS exist: (1) No input schemas are visible in the source code, cannot verify type definitions, constraints, or parameter structure. (2) Descriptions are present but extremely brief (19 - 33 characters), falling below the 20-character floor for quality scoring. (3) No output schemas documented. (4) No error handling guidance visible. (5) Security issues: tools like write_query and create_table expose dangerous SQL operations without clear permission gates, dry-run patterns, or destructive operation warnings. (6) The naming 'read_query' and 'write_query' is generic and does not clearly indicate what each does, 'execute_read_query' and 'execute_write_query' would be clearer. (7) No evidence of idempotency or confirmation patterns for destructive operations. The average of individual tool scores (all capped at 50 due to lack of source verification) yields 28 after applying penalties for missing schemas, short descriptions, and lack of error handling.

• Verify and document the actual tool registration in source code. Provide explicit tool definitions with schema, registration calls, and implementation.
• Add complete input schemas with types, descriptions, and constraints for all parameters. Example for read_query: { 'query': { 'type': 'string', 'description': 'A valid SQLite SELECT query. Must not contain INSERT, UPDATE, or DELETE statements. Parameterized queries with ? placeholders are recommended to prevent injection.' } }
• Expand tool descriptions to 50 - 200 characters, following the LLM-optimized baseline. Include WHAT (e.g. 'Executes a read-only SQL SELECT query'), WHEN (e.g. 'Use before modifying data to verify structure'), and dependencies (e.g. 'Call list_tables() first to discover available tables').
• Add output schemas for all tools. Example for read_query: { 'type': 'object', 'properties': { 'rows': { 'type': 'array', 'items': { 'type': 'object' } }, 'column_count': { 'type': 'integer' } } }
• Implement destructive operation patterns: add a dry_run parameter to write_query and create_table, return a confirmation ID, and require the agent to pass it in a confirm call. Per pattern:confirmation-request, prevent accidental data loss.
• Add error handling guidance to tool descriptions. Example: 'Errors are retryable if they contain 'database locked' or 'SQLITE_BUSY'. User-fixable errors include 'syntax error' (query is invalid) and 'no such table' (use list_tables to discover). Non-recoverable errors include permission denials.'
