Add or update Jest unit tests for fe-tools utilities. An agent skill from MichealWayne/fe-tools.

  • New functions are added
  • Calls npm
  • Existing behavior changes

What it does

Add Tests is an agent skill from MichealWayne/fe-tools. Add or update Jest unit tests for fe-tools utilities. Writes test cases, verifies coverage for common behavior, edge cases, and error inputs. Use when new functions are added, existing behavior changes, or the user asks to add tests across utils, web-utils, node-utils, canvas-utils, or ai-utils.

Its SKILL.md is about 360 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 and Test generation. It works with Jest. The repository describes itself as: 前端开发常用文档/网站地址、样式/js方法封装库、项目模板。提供Chrome拓展程序.

When your agent uses it

  • New functions are added
  • Existing behavior changes
  • The user asks to add tests across utils

Example prompts

  • “/add-tests”

Workflow steps

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

  1. Identify the target package under packages/
  2. Find or create a test file in packages//tests/.
  3. Follow the naming pattern
  4. Cover at least
  5. Use deterministic inputs and avoid external I/O unless required.
  6. Run tests and verify they pass before committing: TEST_API= npm run test.

What it can do on your machine

Read from SKILL.md and the folder at commit 2f4fd1e. 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

    Shell commands in SKILL.md call:

    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

Add Tests loads about 359 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 80 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~359

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 80 words (~359 tokens).
