test

A command that creates integration tests for an API endpoint or resource. Integration tests check several connected parts of an application, such as a route, validation, database, and response.

In plain words
What is it for?
Use it to test valid and invalid API requests, response behavior, authentication requirements, and database or external-service effects.
Why use it?
It saves the work of identifying request formats, authentication, errors, and side effects before writing endpoint 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.

API Test

Generate integration tests for API endpoints.

Load the js-testing skill for Vitest and React Testing Library patterns.

Usage

/test <route_or_resource> [--framework jest|vitest|pytest|gotest]

Arguments

Parse $ARGUMENTS to extract:

  • route_or_resource (required) — Route path (/api/users) or resource name (users)
  • --framework (optional) — Test framework. Auto-detected from project.

Instructions

1. Detect Test Framework

grep -q "vitest\|@vitest" package.json && echo "vitest"
grep -q '"jest"' package.json && echo "jest"
ls pytest.ini pyproject.toml 2>/dev/null && grep -q "pytest" pyproject.toml && echo "pytest"
ls *_test.go 2>/dev/null && echo "gotest"

Also detect:

  • HTTP test client (supertest, httpx, net/http/httptest)
  • Existing test patterns and conventions

2. Read the Endpoint

Find and read the route handler for the specified endpoint. Understand:

  • Request schema (body, params, query)
  • Response schema
  • Auth requirements
  • Error cases
  • Side effects (database writes, external API calls)

3. Generate Tests

Create tests covering:

Happy Path:

  • Valid request → expected response
  • Correct status codes
  • Response body matches schema

Validation:

  • Missing required fields → 400
  • Invalid types → 400
  • Extra fields handled correctly

Authentication (if applicable):

  • No token → 401
  • Invalid token → 401
  • Expired token → 401
  • Insufficient permissions → 403

Not Found:

  • Non-existent resource → 404

Edge Cases:

  • Empty request body
  • Very long strings
  • Special characters in input
  • Duplicate creation
  • Concurrent modifications

Follow existing test patterns in the project. Match:

  • File naming (*.test.ts, *.spec.ts, *_test.go)
  • Setup/teardown patterns
  • Mock/stub conventions
  • Assertion style

4. Test File Location

Place tests following project convention:

  • Co-located: __tests__/resource.test.ts next to route file
  • Separate: tests/api/resource.test.ts
  • Go: resource_test.go in same package

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.

test is a command published in the GitHub repository iwritec0de/app-dev (3 stars, last pushed 4mo ago), licensed MIT. It adds 6 tokens to every session and 605 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
