Usage Guidelines

When to Fetch Guides

  1. Don't fetch unless needed: The skill already covers fundamentals. Only fetch when:

    • User asks about a specific topic not covered in skill
    • Need detailed API information
    • Complex examples required
    • Latest updates needed (docs may be newer than skill)

  2. Fetch specific sections: Use targeted URLs for relevant topics

  3. Combine with skill knowledge: Use fetched content to supplement, not replace, skill knowledge

Example Fetch Patterns

# User asks about command palette
web_fetch("https://textual.textualize.io/guide/command_palette/")

# User needs animation details
web_fetch("https://textual.textualize.io/guide/animation/")

# User wants testing info
web_fetch("https://textual.textualize.io/guide/testing/")

# Need widget reference
web_fetch("https://textual.textualize.io/widgets/data_table/")
