catalyst-appsail
Catalyst AppSail — persistent backend PaaS with managed runtimes (Node.js, Java, Python) and custom Docker containers. 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.

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/catalystbyzoho/agent-skills --skill catalyst-appsail- 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-appsail automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
How It Works
-
Identify the runtime — Managed runtime (Node.js, Java, Python) or custom Docker container.
-
Load
references/appsail-basics.md— for PORT config, project structure, and Dockerfile requirements. For deploy commands and environment variables, loadreferences/appsail-deploy.md. -
PORT rule — Always use
process.env.X_ZOHO_CATALYST_LISTEN_PORT, never hardcodePORTor3000. -
AppSail vs Functions decision — If the user is unsure which to use, apply this matrix:

Triggers
Use this skill for: "AppSail", "persistent server", "Docker on Catalyst", "backend hosting", X_ZOHO_CATALYST_LISTEN_PORT, appsail:add, "catalyst managed runtime", "deploy Express app", "AppSail vs Functions", "long-running process on Catalyst", or "containerized app on Catalyst".

Requires MCP connection — check for CatalystbyZoho tools before any operation. Trigger on 'write a function', 'catalyst function', 'API Gateway', 'Security Rules', 'function not found', 'function returns 401', 'busboy', 'middleware', 'function URL', 'environment variable in function', 'duplicate CORS headers', 'CORS error in browser', 'Access-Control-Allow-Origin multiple values', 'function URL 404', 'execute suffix', 'function timeout', 'function hangs', or any function type question. Do NOT use for persistent servers, long-running processes, or Docker deployments — use catalyst-appsail instead.
catalyst-sdk

This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions

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. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
