experiments: Cursor rule for Cursor

.cursor/deprecated/about-this-project.mdc

about-this-project is a cursor rule for Cursor from reliverse/experiments. It costs 346 tokens per session, scanned A, original, MIT.

Project rules for a TypeScript monorepo, meaning one repository that contains multiple related packages and applications. It explains how the project uses Bun workspaces and Turborepo to manage packages and share task caches.

In plain words
What is it for?
Use it when changing packages or applications, adding TypeScript code, checking dependency direction, or following local AGENTS.md files.
Why use it?
It gives coding agents the context needed to follow the repository's structure and conventions. It also helps prevent invalid imports, circular dependencies, and missed project-specific instructions.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/. Also seen: mentions AGENTS.md.

This is reliverse/experiments's own configuration. It tells Cursor how to work on experiments 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 experiments 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

about-this-project 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

Monorepo Project

This is an Bun monorepo with TypeScript. The project uses bun workspaces for package management. The project uses Turborepo for task local & remote caching. Every submodule of this monorepo, may include its own AGENTS.md file, which you must adhere to.

Project Structure

  • packages/ - Contains all workspace packages (relico, tsconfig, etc)
  • apps/ - Application definitions split by service (cli, scripts, etc)

Code Standards

  • Use TypeScript with strict mode enabled
  • Import shared modules using workspace names, ie. @reliverse/relico
  • Be careful of circular dependencies, apps may rely on packages, not the other way around
  • Prefer single word variable/function names
  • Avoid try {} catch() {} where possible, prefer to let exceptions bubble up
  • Avoid else statements where possible
  • Do not make useless helper functions, inline functionality unless the function is reusable or composable
  • Prefer early returns over nested if statements

Important: Always ensure that you are adding imports for everything. If TypeScript indicates that something is wrong, it may be because you forgot to add some imports.

Dler Rules

  • This project uses @reliverse/dler to manage bun monorepos easily
  • You can check dler's available commands with dler --help
  • Use only latest versions of dependencies
  • Use dler update to update all dependencies in monorepo

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.
