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'.

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/catalystbyzoho/agent-skills --skill catalyst-stratus- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads catalyst-stratus automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.
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
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".

Requires MCP connection — check for CatalystbyZoho tools before any operation.

Trigger on 'AppSail', 'persistent server', 'Docker on Catalyst', 'XZOHOCATALYSTLISTENPORT', or 'long-running process on Catalyst'. Do NOT use for stateless request/response handlers, event-driven functions, or scheduled jobs — use catalyst-functions instead.

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog.

The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
