Unknown method: ${method}

Error message

Unknown method: ${method}

What it means

The third path segment of a github.com URL must be the literal 'blob' for the importer to convert it into a raw URL. URLs whose segment is 'tree', 'commits', 'releases', 'raw', and so on are rejected because they point at a listing or metadata page, not a file.

Solutions

1. Click the actual .md file in the tree so the URL contains /blob/, then copy it
2. Or hand-edit the URL, replacing 'tree' with 'blob', keeping the same ref and path

Example fix

# before
https://github.com/acme/skills/tree/main/src/SKILL.md

# after
https://github.com/acme/skills/blob/main/src/SKILL.md

let segments: Vec<&str> = url.path_segments().map(Iterator::collect).unwrap_or_default();
ensure!(segments.get(2) == Some(&"blob"), "Paste a GitHub blob URL that points to a .md file");

fn is_blob_kind(url: &url::Url) -> bool {
    url.path_segments()
        .and_then(|s| s.nth(2))
        .map(|kind| kind == "blob")
        .unwrap_or(false)
}

When it happens

Trigger: Pasting github.com/owner/repo/tree/main/docs (directory listing), github.com/owner/repo/commits/main, github.com/owner/repo/releases/tag/v1, or any URL where the kind segment differs from 'blob'.

Common situations: The user copied the address bar while browsing a folder (tree view) instead of an opened file; clicking through GitHub UI leaves /tree/ in the URL.
