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', 'X_ZOHO_CATALYST_LISTEN_PORT', or 'long-running process on Catalyst'. Do NOT use for stateless request/response handlers, event-driven functions, or scheduled jobs — use catalyst-functions instead.

- Gen Agent Trust Hubpass
The catalyst-appsail skill is a developer tool for deploying applications to Zoho Catalyst. It is generally safe and adheres to vendor best practices, but it is categorized as low risk due to the inherent potential for indirect prompt injection when processing user-provided code and the use of administrative scopes in provided code templates.

What does this agent skill do?
How It Works
-
Identify the runtime — Managed runtime (Node.js, Java, Python) or custom Docker container.
-
Load
references/appsail-basics.md— for PORT config, environment variables, Dockerfile requirements, and deploy commands. -
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:
Catalyst Functions AppSail Code structure Catalyst-specific templates required Any framework, any format, fully independent Use case HTTP handlers, events, cron, Zoho integrations Persistent servers, long-running processes, Docker Billing Per API call Per instance uptime Dependency management Handled by Catalyst You manage all libraries and frameworks
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".
