readSkillFrontmatterperforms a write side effect despite its "read" name.
readSkillFrontmattercreates the directory and writes a defaultSKILL.mdwhen the file is missing (Lines 307-310). This is documented in the docstring, so it's intentional, but the name suggests a pure read. A caller invoking this function only to check for existing frontmatter would unexpectedly create a file on disk.Consider renaming to something like
ensureSkillFrontmatteror splitting the "create default if missing" step into a separate, explicitly-named function, to make the side effect visible at call sites.🤖 Prompt for AI Agents

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Committed example skill artifacts are stale relative to the current reference-filename aliases. SECTION_FILE_ALIASES in skill-generator.ts is the authoritative naming contract (also matched by README.md's documented layout), but the checked-in example skill under examples/skills/genui-schema-json/ still uses an older naming scheme. This defeats the PR's stated goal of shipping examples "便于本地验证" (for local verification), since regenerating from the current code would produce different filenames than what's committed.

…d file linking Updated the skill generation process to implement a "link only if exists" strategy for intent routing and component categorization. Adjusted documentation to reflect changes in linking behavior, ensuring that only existing files are referenced. Enhanced the formatSkillBody function to accept context for better file management. Improved test coverage for new linking logic and ensured backward compatibility with existing handwritten documents.
