Solutions
- Add `--url <file_url>` pointing to the resource to download
- Verify the URL variable is populated before invoking the command
- Use the tuitui post/send path instead if the intent was to upload a local file
Example fix
// before cc-connect tuitui download --max-bytes 1048576 // after cc-connect tuitui download --url https://example.com/file.png
Defensive patterns
Strategy: validation
Validate before calling
if url == "" {
return errors.New("download requires --url")
} Prevention
- Validate URL variables are populated before invoking download
- Distinguish upload (post/send) from download (fetch remote URL) use cases
- Check the upstream command that produced the URL succeeded
When it happens
Trigger: Running `cc-connect tuitui download` without `--url <url>`, or with an empty --url value.
Common situations: Variable holding the URL was empty in a script, forgot the flag after copy-pasting only the message-related options, or intended to pipe a file via stdin but used the download subcommand.
