test

test is a command for Claude Code from vignesh2027/AI-AGENT-SKILLS. It costs 0 tokens per session (148 once invoked), scanned A, original, MIT.

A command for writing or reviewing automated tests using test-driven development, or TDD: describing expected behavior in tests and using those tests to guide the code. It covers normal, error, boundary, and concurrent cases.

In plain words
What is it for?
Use it to identify test gaps, improve test names and isolation, cover error paths and edge cases, and check that the local test suite remains fast.
Why use it?
It helps reveal missing behavior and weak tests, including failures involving empty or null values, limits, and shared access.

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 6d 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

Load skills/test-driven-development/SKILL.md and agents/test-engineer.md.

Write or review tests for the code described. Ensure:

  1. Happy path — Core behavior tested
  2. Error paths — Every error condition tested
  3. Edge cases — Empty, null, boundary values, concurrent access
  4. Test names — Describe expected behavior, not implementation
  5. Independence — Each test runs in isolation, order doesn't matter
  6. Speed — Tests must run in under 5 minutes for the local suite

For each missing test: describe what behavior it should cover and why it matters. For each poor test: explain what's wrong and provide an improved version.

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.
