2727Content sits in a fixed set of folders, all lowercase and case-sensitive: `skills/`, `commands/`, `agents/`, `hooks/`, and `monitors/`, plus `.claude-plugin/` for the manifest and an optional `icon.png`. Each folder accepts specific file types. `commands/` and `agents/` take `.md` files, `hooks/` and `monitors/` take `.json` files, and `skills/` takes six text formats (`.md`, `.txt`, `.json`, `.yaml`, `.yml`, `.csv`). The root can also hold `README.md`, `LICENSE`, `LICENSE.txt`, `CLAUDE.md`, `CONNECTORS.md`, and `.mcp.json`. Other text files in those six formats, at the root or in folders of your own, are accepted but not used by Claude. Any other file type, anywhere in the archive, is rejected.

29Apart from the optional icon, everything in an archive must be text in UTF-8. There is no way to ship a script, or any other binary asset such as an image, through the card, which is narrower than what members can add to skills on their own devices. File and folder names must be ASCII. Nothing in the archive may start with a dot apart from `.claude-plugin/` and a root `.mcp.json`: repository files such as `.github/` or `.gitattributes` must be left out, while `.gitignore` and `.DS_Store` are dropped for you.

3131Paths inside the zip must use forward slashes: File Explorer's **Compress to ZIP file**, 7-Zip, `tar.exe`, PowerShell 7, and Python's `zipfile` all write them, while Windows PowerShell 5.1's `Compress-Archive` can write backslash paths, which the upload rejects. A zip that wraps everything in one top folder, which is what zipping the plugin folder or downloading a repository as a ZIP produces, works, as long as the repository holds no other dot-prefixed files. The upload looks inside the wrapper. Apple's `__MACOSX/` folders are dropped quietly too. A plugin package can hold up to 50 MB of uncompressed content, whether you upload it on its own or inside a marketplace archive.
