What it does

Testing is an agent skill from hw-native-sys/pypto. Verify testing coverage and run tests for PyPTO project. Use when running tests, checking test coverage, or when the user asks about testing.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `load-env.sh`).

It sits in Testing & QA, covering Test coverage. It works with C++. The repository describes itself as: A community-driven pypto implementation.

When your agent uses it

  • Checking test coverage
  • The user asks about testing

Example prompts

  • “/testing”

Requirements

  • Python 3
  • A Bash shell

Workflow steps

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

  1. Environment: Source .claude/skills/testing/load-env.sh. If the machine-local config doesn't exist, use its safe defaults and show a…
  2. Build Setup: If build is not configured (no build/CMakeCache.txt), run cmake -B build to configure before building.
  3. Build: Ensure project builds without errors or new warnings. Always pass the explicit machine-local limit with --parallel…
  4. Python Path: Set PYTHONPATH correctly
  5. Test Execution: Run all tests and analyze results
  6. Coverage: Verify new features have tests, bug fixes have regression tests
  7. Location: Ensure tests are in proper location (tests/ut/)

What it can do on your machine

Read from SKILL.md and the folder at commit 5f71449. 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

    Ships script files (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • cmake
    • python

    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

Testing loads about 1.1k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 357 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 357 words (~1,054 tokens).

“You are a specialized testing agent. Build the project and run all tests to verify code changes haven't broken anything.”

How do I install Testing in Claude Code?

Run `npx skills add hw-native-sys/pypto --skill testing -a claude-code`. Or copy the skill folder (.claude/skills/testing in hw-native-sys/pypto) into .claude/skills/testing in your project. Claude Code loads it when a task matches its description.

How do I install Testing in Codex?

Run `npx skills add hw-native-sys/pypto --skill testing -a codex`. Or copy the skill folder (.claude/skills/testing in hw-native-sys/pypto) into .agents/skills/testing in your project. Codex loads it when a task matches its description.

Can I use Testing in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hw-native-sys/pypto --skill testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/testing, .gemini/skills/testing, .github/skills/testing and .opencode/skills/testing in your project.

What does Testing need to run?

Going by SKILL.md and its folder, Testing needs a shell for the scripts in its folder and the command-line tools its instructions call (cmake and python). Our summary lists: Python 3; A Bash shell.

Does Testing access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Testing safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Testing use?

Testing has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Testing use?

About 1.1k tokens (SKILL.md is roughly 4.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Testing?
