How to use
- Copy the installation command and review the source package before installing it in your own agent environment.
- Check the source document for required tools, credentials and supported hosts.
- Describe your input and desired deliverable; review the output against the source material.

How It Works
- Bucket naming — Bucket names are globally unique. Use
{app-name}-{project-id-prefix}pattern to avoid collisions. - Load `references/stratus-basics.md` — for upload/download/delete patterns, the 250 GB single-upload limit, signed URL generation, and multipart setup.
- Large files — Multipart upload is recommended (not required) for files ≥ 100 MB. Single-shot upload supports up to 250 GB per object. Load the multipart section of
stratus-basics.md. - Signed URLs — For user-facing direct downloads/uploads, generate a signed URL server-side and return it to the client.
Response Syntax Default
When writing function code that returns a Stratus result to the client, default to native Node.js response syntax — not Express. Advanced I/O exposes raw http.ServerResponse; res.status() and res.json() do not exist unless the user explicitly chose the Express template.
- Native (default):
res.writeHead(200, { 'Content-Type': 'application/json' }); res.end(JSON.stringify(data)); - Express (opt-in only): only if the user has
expressinstalled and wired as middleware
