configure-tests

configure-tests is a skill for Claude Code, Codex from laurigates/claude-plugins. It costs 35 tokens per session (2,014 once invoked), scanned A, original, MIT.

A setup guide for automated tests using Vitest, Jest, pytest, or cargo-nextest.

In plain words
What is it for?
Use it to set up or migrate test frameworks, check their configuration, validate coverage settings, and apply testing conventions.
Why use it?
It helps establish a consistent test setup and catches missing or incorrect coverage configuration before testing becomes harder to maintain.

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

configure-tests 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.

How it starts

The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/configure:tests

Check and configure testing frameworks against best practices (Vitest, Jest, pytest, cargo-nextest).

When to Use This Skill

Use this skill when... Use another approach when...
Setting up testing infrastructure Just running tests (use /test:run skill)
Checking test framework configuration Tests already properly configured
Migrating to modern test frameworks (Vitest, pytest, nextest) Writing individual tests (write tests directly)
Validating coverage configuration Debugging failing tests (check test output)
Ensuring test best practices Simple project with no testing needed

Modern testing stack preferences:

  • JavaScript/TypeScript: Vitest (preferred) or Jest
  • Python: pytest with pytest-cov
  • Rust: cargo-nextest for improved performance

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.
