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 | $0.00320 | $0.00320 |
| Opus 5 | $0.00160 | $0.00160 |
| Sonnet 5 | $0.00064 | $0.00064 |
| Haiku 4.5 | $0.00032 | $0.00032 |
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 yesterday.
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 clientoruse servermarkers.
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
@helmdecorators (Python) when defining tools. - Never hardcode the
baseUrl; useDEFAULT_BASE_URLor environment variables. - Ensure
track_tokensis 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.
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.

cursorrules is a cursor rule published in the GitHub repository jayasukuv11-beep/agenthelm (4 stars, last pushed 6d ago), licensed MIT. It adds 320 tokens to every session, about $0.0016 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.
