.cursorrules

cursorrules is a cursor rule for Cursor from fleXRPL/cursor-rules-dynamic. It costs 1,066 tokens per session, scanned A, original, MIT.

A ruleset for configuring an agent’s version and default programming languages. Its included example describes a TypeScript VS Code extension that analyzes project patterns and manages dynamic .cursorrules files.

In plain words
What is it for?
Use it to guide development of the described TypeScript extension, including code-pattern analysis, rule generation, versioning, validation, and conflict handling.
Why use it?
It provides project-specific instructions about coding languages, structure, quality, and rule handling. The input does not establish which parts are active beyond the shown configuration.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

This is fleXRPL/cursor-rules-dynamic's own configuration. It tells Cursor how to work on cursor-rules-dynamic itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cursor-rules-dynamic configures →

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

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.

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.
