Prism

Ask-Y Claude Plugins

Official Ask-Y plugins for Claude clients (Claude Code, Cowork, etc.).

This marketplace hosts all Ask-Y plugins in one repo. Add it once and install any of the included plugins.

Quick start

/plugin marketplace add Ask-Y-Data-Products/claude-plugins
/plugin install prism@ask-y
/prism:login

/prism:login returns a browser sign-in URL. Open it, sign in, and the plugin remembers the session for the rest of your conversation — no files written, no client restart, no setup step.

Beta customer? See INSTALL.md for the full install guide covering both Claude Code and Claude Cowork (including the ZIP-upload path for Cowork org admins).

Plugins

prism

Claude plugin for the Prism data platform. Browser-based secure sign-in, then list workspaces, projects, and catalog through /prism:* slash commands. Stateless — works in sandboxed plugin runtimes like Claude Cowork. Credentials never transit the chat transcript or the model context.

Commands:

Command	What it does
/prism:login	sign in via browser, start a Prism session for this conversation
/prism:logout	invalidate the current session
/prism:status	show who you're signed in as and when the session expires
/prism:workspaces	list your Prism workspaces
/prism:projects [workspaceId]	list projects in a workspace
/prism:catalog [workspaceId] [projectId] [--variation enlist]	list catalog models
/prism:diag	sandbox diagnostic (backend URL, reachability, session status)

Skill sources live under prism/commands/.

Requirements

• Node.js 18 or newer (the bridge uses native fetch).
• A Claude client that supports the plugin marketplace (Claude Code, Cowork, etc.).
• Network access to the Prism backend. Default: https://appstage.ask-y.ai.

Configuration

The Prism plugin defaults to https://appstage.ask-y.ai. To point at a different backend (local dev, a different stage, prod), set PRISM_BACKEND_URL in the environment that launches your Claude client:

# Windows (PowerShell)
$env:PRISM_BACKEND_URL = "http://localhost:5141"

# macOS / Linux
export PRISM_BACKEND_URL=http://localhost:5141

The default backend URL is set in prism/.claude-plugin/plugin.json and can be overridden without editing the plugin.

Security model

The plugin never asks for your password, token, or any credential inside the chat. Sign-in works via server-side session rendezvous:

1. Plugin asks the backend for a new session. Backend returns an opaque sessionId and a loginUrl.
2. You open the URL in your real browser — same login page as the Prism web app.
3. After you sign in, the backend stores the minted JWT server-side, keyed to the sessionId.
4. Every subsequent /prism:* command sends only the sessionId via the X-Mcp-Session header. The backend resolves it to the cached JWT and executes the request.

The actual JWT never leaves the backend. Your chat transcript sees only the sign-in URL and the opaque sessionId (a session handle with the same lifetime as the JWT — revokable via /prism:logout).

Troubleshooting

• Session expired or not found — run /prism:login to start a fresh session.
• Wrong backend — set PRISM_BACKEND_URL in your environment.
• Sign-in URL doesn't open the right page — verify the backend's /api/auth/mcp-session endpoint is returning a loginUrl that resolves to the Prism login page.
• Something's wrong and I can't tell what — run /prism:diag for a sandbox probe (home, temp, env vars, outbound fetch reachability).

Contributing a new plugin

Each plugin is a self-contained subdirectory at the repo root.

1. Create <plugin-name>/ at the repo root.
2. Add <plugin-name>/.claude-plugin/plugin.json with name, version, description, and optionally mcpServers.
3. Add skill files under <plugin-name>/commands/*.md.
4. Append an entry to .claude-plugin/marketplace.json.
5. Bump the plugin's own version in both plugin.json and the marketplace entry.
