agent-skills: Command for Claude Code

.claude/commands/test.md

test is a command for Claude Code from hamzaMissewi/agent-skills. It costs 23 tokens per session (152 once invoked), scanned A, a copy of test, MIT.

A test-first development workflow, commonly called TDD, where tests are written before the code and initially fail. The code is then implemented, checked, and cleaned up while the tests stay passing.

In plain words
What is it for?
Use it to build features from failing tests, fix bugs with the Prove-It pattern, and verify browser-related fixes with browser testing tools.
Why use it?
It gives new features a clear expected behavior and proves bug fixes with a test that reproduces the problem. Running the full test suite also helps detect regressions, meaning previously working behavior that has broken.

Command for Claude Code

Written for Claude Code: installed under .claude/.

This is hamzaMissewi/agent-skills's own configuration. It tells Claude Code how to work on agent-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-skills configures →

Part of the agent-skills plugin — 24 skills, 9 commands, 4 agents, 1 hook shipped together

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.

Origin

This is a copy

100% identical to test — 0 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 agent-skills:test-driven-development skill.

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
  4. Confirm the test passes
  5. Run the full test suite for regressions

For browser-related issues, also invoke agent-skills:browser-testing-with-devtools to verify with Chrome DevTools MCP.

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.
