Patterns and guidelines for writing Playwright E2E tests in this project — page object rules, assertion placement, and locator conventions.

  • Writing new tests
  • SKILL.md covers Locators belong in page objects, Where to put assertions and Assertions
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Reviewing existing ones

What it does

Writing E2E Tests is an agent skill from Asvarox/allkaraoke. Patterns and guidelines for writing Playwright E2E tests in this project — page object rules, assertion placement, and locator conventions. Use when writing new tests or reviewing existing ones.

Its SKILL.md is about 450 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 End-to-end testing and Browser testing. It works with Playwright. The repository describes itself as: Online Karaoke game with pitch detection in your browser.

When your agent uses it

  • Writing new tests
  • Reviewing existing ones

Example prompts

  • “Use the writing-e2e-tests skill to pattern and guidelines for writing Playwright E2E tests in this project — page object rules, assertion placement…”
  • “/writing-e2e-tests”

What it can do on your machine

Read from SKILL.md and the folder at commit a904310. 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 (its code samples are typescript).

    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

Writing E2E Tests loads about 447 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 94 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~447

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 94 words (~447 tokens).

“.spec.ts files must never locate elements directly — all locators must be exposed via a page object:”
