e2e

A command for generating, running, or investigating end-to-end tests. These tests follow a complete user journey through the application, often using a browser, rather than checking one function in isolation.

In plain words
What is it for?
Use it to test a critical journey, create or update only the needed browser tests, run a focused test or related suite, and record results, captured artifacts, flaky behavior, and gaps.
Why use it?
It focuses testing on the behavior users depend on and reuses the project's existing fixtures, selectors, and page objects. Screenshots, traces, and videos can help explain failures.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

e2e scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/e2e

Request: $ARGUMENTS

Use the e2e-runner agent and the repository's existing browser test setup.

Steps

  1. Identify the critical user journey and required state.
  2. Reuse existing fixtures, selectors, and page objects when available.
  3. Add or update only the tests needed for the requested behavior.
  4. Capture screenshots, traces, or videos when they aid diagnosis.
  5. Run the narrow test first, then the related suite if practical.

CI Baseline

When creating GitHub Actions examples, check and use the latest major versions of actions and the active Node LTS at generation time; if the repository already has .github/workflows/, treat those as the current baseline instead of hardcoding versions.

Output

  • Journey tested
  • Tests changed or generated
  • Commands run and results
  • Artifacts captured
  • Flakes, gaps, or follow-up risks
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

e2e is a command published in the GitHub repository cloudnative-co/claude-code-starter-kit (147 stars, last pushed 8d ago), licensed MIT. It adds 20 tokens to every session and 231 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
