test

A set of testing rules for projects using Vitest, a JavaScript and TypeScript test framework. It specifies Vitest, Node.js, fetch setup, string comparisons, and isolated test stubs.

In plain words
What is it for?
Use it when writing or reviewing Vitest tests that make asynchronous fetch requests or compare multi-line Markdown or HTML.
Why use it?
It prevents tests from using the wrong framework, relying on missing runtime features, or leaking setup and unexpected data between tests.

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

test 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 yesterday.

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.

Origin

This is a copy

100% identical to test — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

  • Always use vitest (never use jest or any other testing framework)
  • Always pin Vitest ≥ 3.1 (or latest) in devDependencies so vi.stubGlobal, unstubGlobals, and other modern helpers exist.
  • Use environment: 'node' and Node 22+ so the built-in fetch and Headers classes are available without polyfills.
  • Trim or normalise strings before comparing multi-line Markdown/HTML: expect(result.trim()) rather than raw literals with trailing spaces.
  • Always place async fetch stubs inside each test (or beforeEach) so they do not bleed unexpected data into other cases.
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.
