## 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 `testing-overview.md` with the `sosumi.ai` Markdown mirror. For example, `/documentation/testing/test` maps to `https://sosumi.ai/documentation/testing/test`.
