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

olore-vitest-4.1.8 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

Vitest Documentation

Vitest testing framework documentation. Use for unit testing, mocking, coverage, snapshots, and Vite-native test configuration.

Quick Reference

Task Entry Point
Getting started contents/guide/index.md
API reference contents/api/
Configuration contents/config/index.md
Mocking contents/guide/mocking.md
CLI reference contents/guide/cli.md
Coverage contents/guide/coverage.md

Troubleshooting contents/guide/common-errors.md

When to use

Use this skill when the user asks about:

  • Writing and running unit or integration tests with Vitest
  • Mocking modules, functions, classes, timers, dates, globals, or network requests
  • Configuring Vitest (vitest.config.ts, test options, environments)
  • Code coverage setup and configuration
  • Snapshot testing
  • Browser mode and component testing
  • TypeScript type-level testing
  • Migrating from Jest or other test runners to Vitest
  • Vitest CLI flags and programmatic API

How to find information

  1. First, read TOC.md for complete file listing organized by directory
  2. Identify relevant section based on user's question
  3. Read specific files for details

TOC.md contains all files organized by directory - always check it first.

Files

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
