From bd76fc958164c054c56007188c9e17857f389a76 Mon Sep 17 00:00:00 2001 From: LifeJiggy Date: Tue, 12 May 2026 15:28:27 +0100 Subject: [PATCH 1/7] feat: add PostgresQueryTool and SqliteQueryTool for database operations Add two new database query tools following the existing buildTool pattern: PostgresQueryTool - Execute SQL queries against PostgreSQL databases via psql CLI. Supports SELECT/INSERT/UPDATE/DELETE/DDL, connection string or env var auth, configurable timeout, and table/csv/json output formats with proper CSV quote handling. SqliteQueryTool - Query local SQLite database files via sqlite3 CLI. Supports read/write modes, validates file extension and existence before execution, includes destructive SQL detection. Both tools include isReadOnly/isDestructive classification, input validation, error handling with partial result support, and renderToolUseMessage/renderToolResultMessage for REPL integration. Tests: 42/42 passing (20 PostgresQueryTool + 22 SqliteQueryTool) --- src/tools.ts | 4 + .../PostgresQueryTool.test.ts | 75 +++++++++ .../PostgresQueryTool/PostgresQueryTool.ts | 159 ++++++++++++++++++
