main

A set of project-wide coding rules for package management, TypeScript, logging, file safety, and required checks.

In plain words
What is it for?
It guides code changes by requiring pnpm, safer TypeScript types, project logging, protected files, and a final pnpm typecheck. It also forbids force-pushing Git history.
Why use it?
It prevents common mistakes such as using the wrong package manager, leaving debug logs in production, changing generated or environment files, or skipping type checks.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 137 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

main 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 2d 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

Coding Rules

Package Manager

  • ALWAYS use pnpm. Never use npm or yarn.

TypeScript

  • Never use any type. Use unknown or explicit types.
  • Never leave console.log in production code. Use the project logger.

File Safety

  • Never modify files under src/generated/.
  • Never modify .env or .env.* files directly.

Commands

  • ALWAYS run pnpm typecheck before finishing.
  • NEVER run git push --force.
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.

main is a cursor rule published in the GitHub repository canblmz1/ruleProb (7 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 137 tokens. 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.
