Sync Docs

This repository probably contains multiple documentation files in Markdown format with .md extension, most of them in a docs/ or documentation/ folder as well as README.md files everywhere. This includes coding agent skills or agent instructions like CLAUDE.md or AGENTS.md.

For every Markdown file, look for statements about how to use the software in this repository or descriptions of how it works, then read the relevant parts of the source code to confirm that these statements are still accurate. If not, modify the Markdown file so that it is accurate, although you might want to warn the user first if the code might actually need to be fixed yet. You don't need to check URLs or other resources outside of this repository.

Think also about strategies for simplifying documentation synchronization in the future: for example, it may not be important to record the exact number of tests or files in particular directories, as these will need to be updated often.

If there are many Markdown files, it might make sense to spawn subagents to work on each Markdown file separately. If there are lots of unrelated changes that need to be committed to source control, it might make sense to commit them in groups of related changes.
