A tool for creating and maintaining end-to-end tests for web apps. These tests use a real browser to check complete user flows, such as signing in or submitting a form.

It helps scaffold Playwright, generate tests from browser flows, cover routes and user roles, record interactions, and diagnose failures from browser traces.

It removes much of the manual work of exploring an app, writing browser tests, and investigating flaky failures.

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 yesterday.

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.

  "description": "End-to-end test authoring and maintenance for web apps via Playwright + Playwright MCP. Claude drives a real browser, reads the accessibility tree, and emits *.spec.ts files that pass — then keeps them passing. /e2e:init scaffolds Playwright in the cwd and registers the MCP server. /e2e:write <flow> drives the browser to perform the flow and emits a green spec. /e2e:crawl discovers every route and generates a smoke spec per route. /e2e:matrix produces a routes × roles coverage suite with reused storageState. /e2e:audit runs the suite, reads trace.zip files, and triages failures by root cause. /e2e:record wraps playwright codegen for manual capture. The author skill enforces selector hygiene (getByRole over CSS), auto-wait discipline, and idempotent test design; the diagnose skill drives trace-driven flaky-test triage. The spec-writer subagent isolates MCP-driven spec authoring from the main context.",

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.
