e2e-test

hideki5123/agent-skill-set/e2e-test/SKILL.md

Run frontend E2E tests with video evidence. Generates a Playwright test from the scenario CSV and runs it via CLI with video recording. Supports Chrome profile reuse (--chrome-profile) for testing with existing cookies, sessions, and extensions via launchPersistentContext. Generates a test report with video, screenshots, and trace. Does NOT modify application code — only creates documents (markdown, CSV, test scripts). Supports --non-interactive for fork / CI use (fails fast on scenario gaps instead of asking). Use when the user asks to run E2E tests, verify frontend behavior, do end-to-end testing, check UI flows, or test a web app. Trigger phrases include "e2e", "E2E test", "end-to-end test", "e2e testing", "frontend test", "UI test", "playwright test", "browser test", "verify the UI", "test this page".

Run a session-based manual test of the project's running app in one of five modes: exploratory, verification, smoke, assessment (UX, localization, accessibility), or AI probe. Use whenever the user asks, in any language, for something to be tested by hand — "manual test", "exploratory test", "bug hunt", "verify the bug fix", "smoke test", "QA this screen", "review this screen's UX", "check the localized copy", "test the AI agent's answers" — or assigns a test design or test-case IDs to execute by hand. Not for writing automated tests.

CLAUDE.md vs AGENTS.md

Agent instruction files

What are agent instruction files?

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.

CLAUDE.md or AGENTS.md?

CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.

What is a skill?

A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.

Can I search my own team's files too?

Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
