Instructions for using Bun, a JavaScript runtime that can also install packages, bundle code, and run tests. They describe Bun as a high-performance alternative for common JavaScript development tasks.

In plain words
What is it for?
Use them when setting up a Bun-based project, installing packages, bundling JavaScript, or running its test suite.
Why use it?
They provide guidance for projects that use Bun instead of, or alongside, other JavaScript tools. This can clarify how to manage dependencies, build the project, and run tests.

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

bun-runtime scanned grade A with 1 finding 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.

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.
