test

test is a command for coding agents from klh/speedy-claude. It costs 23 tokens per session (197 once invoked), scanned A, a copy of test, MIT.

A test-driven development workflow. TDD means writing a test that fails, adding the code that makes it pass, and then improving the code while keeping the test passing.

In plain words
What is it for?
Building features from failing tests, reproducing and fixing bugs, refactoring safely, running regression checks, and testing browser-related issues with developer tools.
Why use it?
It turns expected behavior into a check before implementation and gives bug fixes a reproducible proof. Running the full suite also helps catch regressions, which are new failures caused by a change.

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 today.

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 — 10 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

Invoke the test-driven-development skill. For Jest work, also use klh-testing-patterns.

For new features:

  1. Write tests that describe the expected behavior (they should FAIL)
  2. Implement the code to make them pass
  3. Refactor while keeping tests green

For bug fixes (Prove-It pattern):

  1. Write a test that reproduces the bug (must FAIL)
  2. Confirm the test fails
  3. Implement the fix — root cause only, no drive-by refactors
  4. Confirm the test passes
  5. Run the full test suite for regressions (npm test / dotnet test — both allowlisted, no prompts)

For browser-related issues, use the browser-testing-with-devtools skill with the chrome-devtools MCP. Evidence before assertions: attach real command output when declaring anything green.

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.
