A set of Cursor coding rules for an AI-agent project using Next.js, Tailwind CSS, TypeScript, Supabase, Redis, and related services.

Building and changing the project's web application, database functions, agent tools, billing integrations, and usage-tracking code.

It keeps new code aligned with the project's chosen technologies, naming styles, database practices, SDK rules, and telemetry requirements.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00320	$0.00320
Opus 5.5	$0.00128	$0.00128
Sonnet 5.5	$0.00064	$0.00064
Haiku 4.5	$0.00032	$0.00032

Security

Grade A, and why

cursorrules 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 2mo 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.

What it actually says

AgentHelm Cursor Rules

Optimized for building sovereign AI Agent infrastructure.

Project Architecture

Framework: Next.js (App Router), TailwindCSS, TypeScript.
Database: Supabase (Postgres) with heavily documented RLS policies.
Redis (Upstash): Used for Rate-limiting and Idempotency locks.
SDKs: Python (primary) and Node.js (secondary).
Billing: Cashfree (Indian) / Stripe (International).

Naming Conventions

Database Tables: snake_case (e.g. agent_logs).
TypeScript: PascalCase for components/types, camelCase for variables/functions.
React Components: Function-based components with use client or use server markers.

Primary Stack Preferences

Always use Lucide React for icons.
Prefer Radix UI primitives and Shadcn UI components.
Use Postgres Functions (rpc) for complex atomic database operations.

SDK Usage Standards

Always use the @helm decorators (Python) when defining tools.
Never hardcode the baseUrl; use DEFAULT_BASE_URL or environment variables.
Ensure track_tokens is called after every LLM completion to secure revenue and monitor burn-rates.

Telemetry Patterns

Use dock.progress(percent, message) to ensure Telegram users see live status updates.
Use dock.checkpoint(name, state) before any tool that might fail.

Changes

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.
