Summary

• Add a Chinese community Agent Skill entry for 深知写作助手
• Link the entry to the Qoder public skill repository
• Update the listing to Qoder Public 3.1.4, including Word numbering fixes, red-header AI notice handling, and explicit PDF capability boundaries
• Document automatic phone verification registration and local API key configuration notes

Validation

• Checked the Qoder skill package locally with Python syntax checks, Node syntax check, and release scan
• Confirmed the PR still changes only src/content/skills-zh/dknowc-official-doc-writer.md
• Attempted repository build previously, but the current repository package.json has no build script
