From 57ed3a37e49bc6e43c064aff844d50eac287c08e Mon Sep 17 00:00:00 2001 From: "claude[bot]" <209825114+claude[bot]@users.noreply.github.com> Date: Tue, 7 Oct 2025 13:48:18 +0000 Subject: [PATCH] feat: implement intelligent scan command with ast-grep integration - Add comprehensive project scanning with 4-phase analysis - Integrate @ast-grep/cli for advanced syntax tree analysis - Support AI-powered project understanding with fallback - Generate structured JSON output with file/directory summaries - Add configurable include/exclude patterns and scan depth - Provide transparent logging for each analysis phase - Create task-master scan command with full CLI options This addresses issue #78 by enabling quick project structure analysis for easier Task Master adoption on existing projects.
