From 1840d0654d558144fc17aa15c02de9b45037591d Mon Sep 17 00:00:00 2001 From: tegwick Date: Thu, 25 Sep 2025 03:30:10 +0200 Subject: [PATCH] =?UTF-8?q?feat:=20Complete=20Issue=20#14=20-=20Database?= =?UTF-8?q?=20Query=20CLI=20Interface=20=E2=AD=90=20MAJOR=20MILESTONE?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement comprehensive database query interface with multiple output formats: • Add query command for executing read-only SQL queries with security constraints • Add schema command for database structure inspection • Add metadata command for file information display • Support table, JSON, and YAML output formats across all commands • Implement SQL injection prevention and safety checks • Add tabulate dependency for enhanced table formatting • Create 35 comprehensive tests covering all functionality This delivers the core USP "Relational Document Metadata" by making the database fully queryable through CLI commands with multiple output formats. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- markitect/cli.py | 204 +++++++++++ markitect/database.py | 100 ++++- pyproject.toml | 2 +-
