description	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'.
metadata	{"version":"2.1.2"}

How It Works

1. Bucket naming — Bucket names are globally unique. Use {app-name}-{project-id-prefix} pattern to avoid collisions.
2. Load references/stratus-basics.md — for upload/download/delete patterns, the 250 GB single-upload limit, signed URL generation, and multipart setup.
3. 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.
4. Signed URLs — For user-facing direct downloads/uploads, generate a signed URL server-side and return it to the client.

Triggers

Use this skill for: "Stratus", "object storage", "file storage", "upload file", "download file", "signed URL", "pre-signed URL", "multipart upload", putObject, getObject, "bucket", "Stratus bucket", "store files on Catalyst", "Stratus vs File Store", "250GB limit", or "file download link".
