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 | $0.00166 | $0.00166 |
| Opus 5.5 | $0.00066 | $0.00066 |
| Sonnet 5.5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00017 | $0.00017 |
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 1mo 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
Cursor Rules for Nex
Refer to AGENTS.md for the full set of principles.
- Locality: UI and logic belong in the same Page module.
- Routing: File system based. No
router.ex.
- Navigation: Use
hx-boost="true"on the<body>tag for SPA-like speed. - CSRF Global: Layout should include
{meta_tag()}in<head>andhx-headers={hx_headers()}on<body>for HTMX requests.
- Actions: Use
hx-post="/func_name"to call module functions. - API: Use
Nex.json/2insrc/api/.
Always follow the Locality of Behavior (LoB) principle.
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 gofenix/nex (106 stars, last pushed 4mo ago), licensed MIT. It adds 166 tokens to every session, about $0.0007 per session on Opus 5.5.
