What it does

E2E Setup is an agent skill from AI-Builder-Club/skills. Set up an end-to-end test suite in any repo, following practices that make e2e a reliable per-PR gate: real flows over bypass, layered assertions, a reusable auth/session helper, video+trace evidence, and a compounding suite. Use when a repo has no e2e (or weak e2e) and you want system-level tests — "set up e2e", "add end-to-end tests", "scaffold a test gate".

Its SKILL.md is about 950 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. The repository describes itself as: Codebase harness + loop engineer.

When your agent uses it

  • A repo has no e2e (or weak e2e) and you want system-level tests — set up e2e
  • Add end-to-end tests
  • Scaffold a test gate

Example prompts

  • “set up e2e”
  • “add end-to-end tests”
  • “scaffold a test gate”
  • “/e2e-setup”

Workflow steps

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

  1. Stand the app up reproducibly — see dev-local-setup. The e2e suite **never
  2. Pick the framework that fits (Playwright for browser; your HTTP client for API).
  3. Explore the flow live first (don't guess selectors), then crystallize it into
  4. Keep the gate small: a handful of critical journeys, deterministic. Each new

What it can do on your machine

Read from SKILL.md and the folder at commit 917780c. 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.

    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

E2E Setup loads about 952 tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 502 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~93
When it runs · the whole SKILL.md, loaded when a task matches
~952

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 502 words (~952 tokens).

“E2e tests verify the whole running system through the app (browser/API), not one module. They are the per-PR gate. Pairs with dev-local-setup (a reproducible local stack) and verifier-setup (which scaffolds the repo's /verify skill — the verify→ship loop this gate…”
