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.

Skill instructions

Rendered from the published SKILL.md, 26 lines.

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, load references/appsail-deploy.md.
PORT rule — Always use process.env.X_ZOHO_CATALYST_LISTEN_PORT, never hardcode PORT or 3000.

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".

References

Reference	Load when the query is about…
`references/appsail-basics.md`	Runtimes, project structure, app-config.json fields, Node.js/Docker templates, SDK version
`references/appsail-deploy.md`	Deployment commands (Path A/B/C), env variables, health checks, AppSail URL pattern, configurations
`references/appsail-crossorigin.md`	Slate + AppSail cross-origin errors, CORS setup via MCP, `catalyst_auth`, custom domain SSL

tao-run-platform
TAO Execution SDK for submitting and monitoring GPU training jobs on supported platforms (Brev, SLURM, local Docker, Kubernetes). Use when the user wants to run TAO jobs through the SDK, get job tracking, S3 I/O wrapping, multi-node distributed training, or platform-specific features that docker-run can't provide. Trigger phrases include "use the TAO SDK", "call tao_sdk", "AutoMLRunner", "ActionWorkflow", "Job handles", "S3 I/O wrapping", "TAO platform run".
