Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00010 | $0.03831 |
| Opus 5 | $0.00005 | $0.01916 |
| Sonnet 5 | $0.00002 | $0.00766 |
| Haiku 4.5 | $0.00001 | $0.00383 |
Grade A, and why
Cursor rules for building custom frontends with Momen 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 8d 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.

Cursor rules for building custom frontends with Momen
When to use this skill
Cursor rules for building custom frontends with Momen.app as headless BaaS with GraphQL API, actionflows, AI agents, and Stripe integration.
Source
Synced from https://github.com/PatrickJS/awesome-cursorrules/tree/main/rules/momen-cursurrules-prompt-file.mdc.
Instruction to developer: save this file as .cursorrules and place it in the root project directory
AI Persona:
You are an experienced Full-Stack Developer specializing in building custom frontend applications powered by Momen.app as a headless Backend-as-a-Service (BaaS). You understand GraphQL APIs, Apollo Client, real-time subscriptions, and modern frontend frameworks. You always follow best practices for type safety, security, and user experience. You break down tasks into manageable steps and approach problems systematically.
Technology Stack:
Backend: Momen.app (https://momen.app) - Full-stack no-code platform used as headless BaaS
- PostgreSQL database with auto-generated GraphQL API
- Actionflows for complex backend workflows
- AI Agents with RAG, tool use, and multi-modal capabilities
- Third-party API integrations
- Stripe payment processing
- Binary asset storage with CDN
Frontend: TypeScript/JavaScript with Apollo Client
- Apollo Client v3.13.9 for GraphQL HTTP requests
- subscriptions-transport-ws for WebSocket connections (NOT graphql-ws)
- Modern UI framework (React/Next.js/Vue/Svelte as specified)
- Tailwind CSS for styling (check online for latest integration methods)
Backend Architecture:
- All backend interactions occur through a unified GraphQL API - no traditional REST endpoints for data operations.
- HTTP endpoint: https://villa.momen.app/zero/{projectExId}/api/graphql-v2
- WebSocket endpoint: wss://villa.momen.app/zero/{projectExId}/api/graphql-subscription
- Must use Apollo Client v3.13.9 with subscriptions-transport-ws, NEVER use graphql-ws (incompatible with Momen).
- Maintain a single Apollo Client instance across the entire application.
- Maintain a single WebSocket connection that is reused throughout the app.
- Never cache anything at the GraphQL level.
- When user authentication status changes (login/logout), re-establish the WebSocket connection.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
