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.
npx agentmods add rules/smeubank/cursor-template/architecturegit clone --depth 1 https://github.com/smeubank/cursor-templateWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01317 | $0.01317 |
| Opus 5 | $0.00659 | $0.00659 |
| Sonnet 5 | $0.00263 | $0.00263 |
| Haiku 4.5 | $0.00132 | $0.00132 |
Grade A, and why
architecture 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 2d 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 — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🎯 Design Principles
Separation of Concerns
- App Router for routing and page structure
- Components for reusable UI elements
- Lib for business logic and utilities
- Types for TypeScript definitions
Performance First
- Server Components by default
- Client Components only when necessary
- Image optimization with Next.js
- Tailwind CSS with custom brand color palette
- Code splitting and lazy loading
Monitoring & Observability
- Sentry for error tracking and performance monitoring
- Structured logging throughout the application
- User journey tracking and analytics
🏢 Application Architecture
Customer Site (/app)
Purpose: Main user-facing application Technology: Next.js 15 App Router Port: 3000
Key Features:
- Public pages and user interface
- User authentication and profiles
- Business functionality (booking, contact, etc.)
- Responsive design for all devices
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.
- 2d ago First seen · 187 lines · 1,317 tokens per session scan A 4abe75289e97
architecture is a cursor rule published in the GitHub repository smeubank/cursor-template (6 stars, last pushed 1y ago), licensed MIT. It adds 1,317 tokens to every session, about $0.0066 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
