Use when an extension change needs agentic verification in a real browser — content scripts, popup UI, network calls, fonts, console errors. Spawns the agent's own Chrome via the chrome-devtools-ext MCP. Complements (does not replace) human-eye verification via `pnpm dev:browser`.
Use when about to write or modify a Playwright e2e spec under `packages/danmaku-anywhere/e2e/`. Points at the canonical doctrine and surfaces the load-bearing rules so the spec doesn't get bounced in review.
Use when you need to load a specific published preview/nightly extension build into the agent's MCP browser by run-number, branch name, or tag. Faster than rebuilding locally when you only want to exercise an existing artifact.
Use when evaluating review comments from AI reviewers (gemini-code-assist, copilot-pull-request-reviewer) on a PR. Default to assuming the reviewer is right; verify before declining. Includes reporting in chat and resolving threads after handling.
Run and debug Agmente ACP end-to-end scenarios from the repo-owned e2e/scenarios/acp specs. Use when validating ACP websocket compatibility, session creation, cwd handling, reconnect flows, or reproducing ACP-only UI failures against a real local ACP backend.
Run and debug Agmente iOS end-to-end tests against a real local Codex CLI app-server instance. Use when validating Codex websocket/protocol compatibility, connect/initialize/thread flows, or reproducing Codex-only UI test failures with an actual local Codex server.
Kolo is a text-based Python debugger that captures every executed function, return value, local variable, HTTP request, and SQL query into greppable trace files. Use this skill for tricky debugging challenges, to verify that code behaves as expected at runtime, and to see the real data and values passing through the code. Use it to see the real data returned by sql queries or the real http data sent and received. Use it when the user reports something is not working, but you're not sure why - even if the user doesn't explicitly mention "kolo" or "debugging".
Drives iOS/Android mobile devices via Appium MCP. Use for verifying mobile bugs, E2E tests, and navigating real device clouds (LambdaTest/BrowserStack).
