test

test is a command for Claude Code from vinvcn/addyosmani-agent-skills-zh. It costs 23 tokens per session (166 once invoked), scanned A, original, MIT.

A test-driven development workflow, or TDD, where tests describing the expected behavior are written before the implementation. For bugs, it first adds a test that reproduces the failure.

In plain words
What is it for?
Use it for new features and bug fixes, including browser-related problems that need additional browser inspection.
Why use it?
It verifies that a feature or bug fix is demonstrated by a failing test before the code changes, then checks that the fix works and does not break other tests.

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 11d 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

调用 agent-skills:test-driven-development skill。

对于 new features:

  1. 编写描述预期行为的 tests(它们应该 FAIL)
  2. 实现代码让它们通过
  3. 在保持 tests green 的同时 refactor

对于 bug fixes(Prove-It pattern):

  1. 编写复现 bug 的 test(必须 FAIL)
  2. 确认 test 失败
  3. 实现 fix
  4. 确认 test 通过
  5. 运行完整 test suite 检查 regressions

对于 browser-related issues,还要调用 agent-skills:browser-testing-with-devtools,并用 Chrome DevTools MCP 验证。

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.
