What it does

Phoenix Playwright Tests is an agent skill from Arize-ai/phoenix. Write Playwright E2E tests for the Phoenix AI observability platform. Use when creating, updating, or debugging Playwright tests, or when the user asks about testing UI features, writing E2E tests, or automating browser interactions for Phoenix.

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `EXAMPLES.md` and `UI-COMPONENTS.md`).

It sits in Testing & QA, covering LLM observability, Browser testing and End-to-end testing. It works with Playwright. The repository describes itself as: AI Observability & Evaluation.

When your agent uses it

  • Debugging Playwright tests
  • The user asks about testing UI features
  • Writing E2E tests
  • Automating browser interactions for Phoenix

Example prompts

  • “/phoenix-playwright-tests”

Workflow steps

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

  1. Role selectors (most robust)
  2. Label selectors
  3. Text selectors
  4. Test IDs (when available)
  5. CSS locators (last resort)

What it can do on your machine

Read from SKILL.md and the folder at commit 52f76fc. 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:

    • pnpm

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

  • Network

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

Phoenix Playwright Tests loads about 3.6k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 834 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~3.6k

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 834 words (~3,590 tokens).

“Write end-to-end tests for Phoenix using Playwright. Tests live in js/app/tests/ and follow established patterns.”
