工具清单
工具（5）
🟡create_upload_link(content_type, filename, path, ttl_hours)
Relay a file of any size up to 100 MB. Save the file to local disk first, call this with its path, then run the returned curl command in your shell to upload it. The download link works as soon as the upload finishes. Requires outbound network access to code.easyllms.com; if curl is blocked, ask the user to allow that domain in their sandbox network settings (on claude.ai: Settings > Capabilities > Code execution).
