catalyst-stratus
Catalyst Stratus — object storage service with upload/download, signed URLs, and multipart upload support. Stratus uses its own SDK-based APIs (not S3-API-compatible). Migrate from AWS S3 or GCS using the Stratus Migration Tool. Trigger on 'Stratus', 'object storage', 'upload file', 'signed URL', 'putObject', 'getObject', or 'bucket'.

What does this agent skill do?
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
