From 74d7debdf24d38169df89f9a3d7f7a027e9a6fd5 Mon Sep 17 00:00:00 2001 From: helm30 Date: Tue, 19 May 2026 22:22:13 +0800 Subject: [PATCH 1/4] feat(skill): add YAML auto-repair for unquoted colons in frontmatter Enhance MarkdownSkillParser to automatically repair YAML frontmatter containing unquoted colon-space patterns in scalar values. When SnakeYAML fails to parse, the parser now attempts to quote problematic values before giving up.
