A Git-based hosting service for deploying frontend applications such as React, Next.js, Vue, Angular, Svelte, or Astro. It supports preview deployments for checking changes before release.

In plain words
What is it for?
Use it to host frontend websites and create preview deployments for framework-based web projects on Catalyst.
Why use it?
It provides a deployment path for the part of an application that runs in the browser, separate from backend APIs and server-side processing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

catalyst-slate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ PRE-FLIGHT CHECK — Slate activation (one-time, per project): Before any Slate command, confirm Slate is activated in the console. Open the Catalyst console → your project → Slate (left sidebar) → click Start Exploring. This is a one-time step. Skipping it means catalyst deploy slate fails with HTTP 400 even though slate:create succeeds locally.

How It Works

  1. Check if Slate is activated — Use MCP: call CatalystbyZoho_List_All_Slate_Apps with the project ID.
    • If it returns apps or an empty list → Slate is activated. Proceed.
    • If it returns INVALID_URL_PATTERN → Slate is not yet activated. This is NOT an MCP bug — it means the service needs a one-time console activation. Tell the user:

      "Please open the Catalyst console, go to your project → Slate (left sidebar) → click Start Exploring. This is a one-time step that takes 5 seconds. Let me know when done and I'll continue." Wait for confirmation, then proceed.

    • Never fall back to Web Client (legacy) because Slate isn't activated yet. Web Client is deprecated — Slate is always the right choice for frontend hosting. The one-time activation is not a reason to change the approach.

    If Slate was not selected during catalyst init, run catalyst slate:create --name <name> --framework <framework> --default immediately after init. This command updates catalyst.json and prompts for the source directory automatically — it is faster than manual setup and should be the default recommendation.

  2. Check if Slate app exists — If no app exists yet, run catalyst slate:create --name <name> --framework <framework> -ni to scaffold one. If Slate was not selected during catalyst init, run this immediately after init.
  3. Load references/slate-basics.md — for framework setup, slate-config.toml format, and baseUrl configuration.
  4. Cross-domain calls — If the query involves calling functions from a Slate app, apply the full URL + generateAuthToken() + CORS whitelist pattern.

    ⚠️ Migrating from basic client hosting? Relative paths like /server/fn/execute that worked in basic client silently break on Slate — Slate is served from *.onslate.com while functions are on *.catalystserverless.com. Every function call must become an absolute URL. Find and replace all relative /server/... paths with the full https://<project>.catalystserverless.com/server/... URL and add generateAuthToken() headers.

  5. Deploy — Before deploying, confirm Slate is activated in the console (Console → Slate). slate:create runs locally and succeeds without activation — the first backend call happens at deploy time, which fails with HTTP 400: Please access the Slate service in your project's console before deploying if not activated. Once confirmed: catalyst deploy slate <name> -ni deploys to the current environment. Preview URLs are available after the build completes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
