functest

functest is a skill for Claude Code from syy12335/Environment-Runtime. It costs 23 tokens per session (357 once invoked), scanned A, original, MIT.

A workflow task type for defining the target and focus of a functional test, which checks whether a feature works as intended. It passes that testing target into the workflow and reports whether the task succeeded or failed.

In plain words
What is it for?
Use it to specify the feature or object to test, the goal of the current test, and any particular concerns to examine.
Why use it?
It turns a testing request into a clear, specific target instead of leaving the workflow to decide what to test. It can also describe what to check when repeating a test after a failure.

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

functest 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/run.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Functest Workflow Type

定位

  • functest 用于生成“功能测试目标(target)”。
  • controller 负责确定:本轮测什么、围绕什么测、重点朝哪个方向测。
  • 该 type 命中后会直接进入 workflow,不再交给 executor agent loop。

场景步骤模板

  1. 明确对象的直接功能测试:直接 generate_task(functest)。
  2. 带关注点的功能测试:把用户显式关注点写入 task_content。
  3. 基于失败点复测:可使用 previous_failed_track {} 补全事实后 generate_task(functest)。
  4. 对象不明确:必要时 build_context_view 后再生成任务。

生成原则

  • task_content 是当前任务 target,不是完整执行配置。
  • 写清测试对象、本轮目标、必要关注方向。
  • 对“对象明确、任务类型明确”的请求,不得默认继续 observe。

Workflow I/O

  • 入口:scripts/run.py
  • 调用:run(*, task_content: str) -> dict
  • 返回:{"task_status": "done|failed", "task_result": "..."}
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
