Fetching More Docs

1. Search this skill's local .md files first.
2. If the topic is not here, check the other installed Apple skills you have available by their names, descriptions, or SKILL.md frontmatter, then grep their local files. This is faster and uses less context than fetching new docs from the internet.
3. If no installed skill has the page, use the relevant documentation path from swiftui-overview.md with the sosumi.ai Markdown mirror. For example, /documentation/swiftui/button maps to https://sosumi.ai/documentation/swiftui/button.

Usage Instructions

1. Check downloaded files first - Grep the local .md files for your topic
2. Use the overview as an index - Search swiftui-overview.md for documentation paths
3. Fetch only when needed - If no installed skill has the page, use sosumi.ai with documentation paths from the overview

Example workflow:

# Looking for info on modifiers?
grep -i "padding" view-protocol.md

# Need full Text documentation? Check the local file first.
grep -i "font" text.md
