What it does

Playwright E2E Tests is an agent skill from onyx-dot-app/onyx. Write and maintain Playwright end-to-end tests for the Onyx application. Use when creating new E2E tests, debugging test failures, adding test coverage, or when the user mentions Playwright, E2E tests, or browser testing.

Its SKILL.md is about 2.8k 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 Browser testing and End-to-end testing. It works with Playwright and Model Context Protocol. The repository describes itself as: Open Source AI Platform - AI Chat with advanced features that works with every LLM.

When your agent uses it

  • Creating new E2E tests
  • Debugging test failures
  • Adding test coverage
  • The user mentions Playwright

Example prompts

  • “/playwright-e2e-tests”

Workflow steps

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

  1. Descriptive test names — clearly state expected behavior: "should display greeting message when opening new chat"
  2. API-first setup — use OnyxApiClient for backend state; reserve UI interactions for the behavior under test
  3. User isolation — tests that modify visible app state (sidebar, chat history) should run as the worker-specific user via…
  4. DRY helpers — extract reusable logic into utils/ with JSDoc comments
  5. No hardcoded waits — use the auto-retrying matchers (web/tests/e2e/README.md), waitFor, or waitForLoadState; never waitForTimeout
  6. Parallel-safe — no shared mutable state between tests. Prefer static, human-readable names (e.g. "E2E-CMD Chat 1") and clean up resources…
  7. Error context — catch and re-throw with useful debug info (page text, URL, etc.)
  8. Tag slow tests — mark serial/slow tests with @exclusive in the test title
  9. Visual regression — use expectScreenshot() for UI consistency checks
  10. Minimal comments — only comment to clarify non-obvious intent; never restate what the next line of code does

What it can do on your machine

Read from SKILL.md and the folder at commit 744ca37. 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:

    • bunx
    • curl

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

  • Network

    No URLs in SKILL.md. Its commands use bunx and curl, 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 these keys or tokens, usually read from environment variables:

    • TEST_ADMIN_CREDENTIALS

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

Context cost

Playwright E2E Tests loads about 2.8k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 991 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:47
    - `web/.vscode/.env` may be **absent** — `dotenv` skips it silently (fine for most tests). One exception: `tests/e2e/mcp

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 991 words (~2,808 tokens).

“Spec-authoring rules live in web/tests/e2e/README.md — the Page Object Model, locator priority, and auto-retrying matchers. Read it before adding or changing a spec. This skill covers the surrounding workflow: layout, environment, running tests, auth, and Onyx-specific utilities.”
