已根据技能编写指南检查 894 个技能: 59 个前体材料约束违规

I ran a checker over the 894 SKILL.md files in cli-tool/components/skills/ against Anthropic's skill authoring guidelines. Most of the collection is clean. A few things come up often enough to be worth a single sweep, so I am opening one issue rather than a pile of small ones.
