Testing

What it does

When your agent uses it

• The user requests testing
• Provides relevant inputs for this workflow

Example prompts

• “/testing”

Requirements

• Python 3
• Node.js

Workflow steps

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

1. 1Analyze the source code. Read the target file or module and build a dependency graph of its functions, classes, and external interactions…
2. 2Identify test cases. For each function or method, enumerate the scenarios that need coverage: happy-path inputs, boundary values, invalid…
3. 3Write the tests. Generate well-structured test code using the project's existing test framework (e.g., pytest, Jest, JUnit). Each test…
4. 4Run the tests. Execute the test suite using the appropriate runner command. Capture the full output including pass/fail status, assertion…
5. 5Analyze coverage. Run the test suite with coverage instrumentation enabled (e.g., pytest --cov, jest --coverage). Parse the coverage…
6. 6Suggest improvements. Based on coverage gaps and code complexity, recommend additional test cases. Suggest refactoring opportunities that…

What it can do on your machine

Read from SKILL.md and the folder at commit 75865a5. 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:

  • pytest
  • npx
  • jest
  • mvn
  • go
  • cargo

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

• Network

  No URLs in SKILL.md. Its commands use npx, 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

Testing loads about 2.3k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 773 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~54

When it runs · the whole SKILL.md, loaded when a task matches

~2.3k

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

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.
