What it does

Unit Test Scaffold is an agent skill from zhuyansen/agent-skills-hub. Create a unit test file for a module with one test per public function and the edge cases to cover.

Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Unit testing. The repository describes itself as: Discover and compare open-source Agent Skills, tools & MCP servers — with quality scoring, trending analysis, and automated GitHub sync. The licence is MIT.

When your agent uses it

  • Tasks that involve Unit testing

Example prompts

  • “/unit-test-scaffold”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Read the input the user points to. If none is given, ask for the file or text.
  2. Do the task described above, step by step, and keep the user's own wording where it matters.
  3. Show the result, then a short list of what you changed or found, so the user can check it.

What it can do on your machine

Read from SKILL.md and the folder at commit 2862275. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unit Test Scaffold loads about 197 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 121 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~197

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

When to use

Use this skill when the user asks for it by name or describes this task. Do not use it for unrelated work.

Steps

  1. Read the input the user points to. If none is given, ask for the file or text.
  2. Do the task described above, step by step, and keep the user's own wording where it matters.
  3. Show the result, then a short list of what you changed or found, so the user can check it.

Notes

  • Keep changes small and reversible.
  • Say plainly when the input is incomplete instead of guessing.
