Checkly
ChatGPT pluginSynthetic monitoring as code
Checkly is synthetic monitoring as code: API checks, browser checks, URL and uptime monitors, and Playwright Check Suites that run from global locations and alert you when something breaks.
This plugin bundles two skills and the Checkly MCP server. The skills teach Codex how to scaffold monitoring-as-code projects with the Checkly CLI, write API and browser checks, and apply Playwright best practices for stable end-to-end tests. The MCP server connects to your Checkly account so Codex can list and inspect checks, read check results and test sessions, trigger checks, run root cause analyses, and manage API checks, monitors, check groups, and status page incidents.
Intended for developers and SREs who already use Checkly or want to add monitoring to a project without leaving their editor. A Checkly account is required; the MCP server authenticates with OAuth.
Limitations: Playwright Check Suites and checks whose code lives in a repository are managed with the Checkly CLI, not through MCP tools. Environment variables can be read but not created or updated from this plugin.

playwright-best-practices-for-agents
Agent-first best practices for writing, structuring, debugging, and stabilizing Playwright tests in TypeScript/JavaScript, built around Playwright's agent CLI (`playwright-cli`) and no-GUI agentic debugging flows. Use when authoring or reviewing Playwright tests: choosing locators, writing web-first assertions, fixing flaky tests, handling authentication (SSO/2FA), mocking network/API requests, structuring projects and fixtures, generating test data, building forms and validation, pressing keys and keyboard shortcuts, hovering and other mouse actions, handling native alert/confirm/prompt dialogs, uploading or downloading files, testing iframes, multiple tabs/popups or multi-user flows, mobile and device emulation, mocking time and dates, visual regression and screenshots, tagging and annotating tests, catching console errors, testing error/offline/loading states, configuring global setup, or running Playwright in CI.
