cursor-rule-template

cursor-rule-template is a cursor rule for coding agents from equinor/fusion-skills. It costs 182 tokens per session, scanned A, original, MIT.

A starter structure for Cursor rules, which are written instructions that guide how Cursor behaves while working with code. It shows the settings and formats for rules that always apply, match certain files, are selected by the agent, or are manually requested.

In plain words
What is it for?
Use it to create a .cursor/rules file, choose its activation mode, and write concise instructions for the coding agent.
Why use it?
It gives developers a consistent place and format for defining when coding instructions should be active.

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.

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.

Security

Grade A, and why

cursor-rule-template 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 5d 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 Rule — Starter Template

Use this as the starting structure for .cursor/rules/<name>.mdc. Set frontmatter fields to control activation mode, then add concise, imperative directives.

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.
