Run browser encrypted JS in Node.js (environment patching). env_core.js provides function disguise/prototype chain/Proxy engine, Claude writes stubs on demand in run.js according to the diagnosis report. TRIGGER when: user says "environment patching", "module extraction", "run in Node", "webpack module extraction", "environment simulation", "run JS in Node", or needs to run independently without browser after finding the encryption entry. DO NOT TRIGGER when: only debugging in browser, doing AST deobfuscation, or writing ordinary Node.js code.
Review Skill definition quality. Use when user asks to "review skill", "check skill quality", "validate skill", "lint skill", "review my skill", or wants to check if a Skill follows best practices. For execution trace analysis, use when user explicitly mentions "analyze execution", "review trace", or "evaluate execution process". Do NOT use for runtime debugging (use agent-debug skill), code review (use code-review skill), or general file validation.
Use this skill whenever writing, reviewing, debugging, or refactoring TypeScript code that uses the Effect-TS library. Trigger when you see imports from `effect`, `effect/*`, or any `@effect/*` scoped package (schema, platform, sql, opentelemetry, cli, cluster, rpc, vitest). Trigger on Effect-specific constructs: Effect.gen generators, Schema.Struct/Schema.Class definitions, Layer/Context.Tag/Service patterns, Effect.pipe pipelines, Data.TaggedError/Data.Class error types, Ref/Queue/PubSub/Deferred concurrency primitives, Match module, Config providers, Scope/Exit/Cause/Runtime patterns, or any code using Effect's typed error channel (E parameter). Also trigger when the user asks about Effect patterns, migration from Promises/fp-ts/neverthrow to Effect, or how to structure an Effect application. Covers the full ecosystem: core Effect type, Schema validation, error management, concurrency (fibers, queues, semaphores, pools), streams/sinks, services and layers (DI), resource management, scheduling, observability, platform APIs, and AI integration. Do NOT trigger for React's useEffect, Redux side effects, or general English usage of "effect" unless the context clearly involves the Effect-TS library.
Browser automation and web browsing via managed Chrome instance. Open URLs, browse websites, interact with web pages, scrape/extract content, debug web pages, fill forms, take screenshots, and maintain login sessions with persistent profiles. Supports anti-detection for sites with bot protection. Use when: opening links/URLs, viewing web pages, logging into websites, extracting or scraping page content, debugging frontend issues, interacting with web applications, or any task requiring a browser. Triggers: open URL, open link, browse, visit website, view page, scrape, extract content, debug page, login to site, web interaction, screenshot, fetch page, browser, 打开链接, 打开网页, 浏览器, 抓取内容, 调试网页, start browser, stealth chrome, anti-detection, persistent login, browser profile, connect CDP.
Use this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
Manages MongoDB Atlas Stream Processing (ASP) workflows. Handles workspace provisioning, data source/sink connections, processor lifecycle operations, debugging diagnostics, and tier sizing. Supports Kafka, Atlas clusters, S3, HTTPS, and Lambda integrations for streaming data workloads and event processing. NOT for general MongoDB queries or Atlas cluster management. Requires MongoDB MCP Server with Atlas API credentials.
Official Roblox Studio MCP server tools reference. What each tool does, how to use it, reliability patterns, and workflows for script editing, building, playtesting, and debugging. Use when the AI has an MCP connection to Roblox Studio.
Deep linter reference for authoring or debugging a vigiles enforce() rule — plugin tables, AST selectors, type-aware rules, auto-fix, and edge cases for ESLint, Ruff, Pylint, RuboCop, and Stylelint. Use when you need the exact rule name or config for a specific linter, not for running a linter.
CI/CD status queries for GitHub Actions (gh) and GitLab CI (glab). Check pipeline status, failing jobs, workflow runs, job logs, and merge readiness. Use when checking CI status, debugging build failures, viewing job logs, watching pipeline progress, or configuring gh/glab CI read-only allowlists. Not for PR workflows (git-pr), git commits (git-commit), or deploy/release ops
Use this skill whenever the user wants to design or implement caching in a Next.js 16+ App Router project — setting up the "use cache" directive, building a cache tag registry, wiring mutations to invalidation utilities, structuring Suspense boundaries for partial prerendering, handling personalized content near cache boundaries, choosing cacheLife profiles, calling cacheTag / updateTag / revalidateTag correctly, migrating from unstable_cache, or debugging stale or incorrectly fresh data. Trigger even when the user only describes their domain (e.g. "I have a posts table") and asks how to cache it properly.
Full-stack Meteor 3.x development with React, MongoDB, async APIs, methods, pub/sub, and GraphQL. Use this skill when working on any Meteor project — writing methods, publications, subscriptions, React data containers, collection helpers, ORM patterns, REST APIs with accounts-express, Meteor-to-React integration via useTracker/withTracker, async migration from Fibers, optimistic UI, DDP, or debugging Meteor-specific issues like circular dependencies, method stubs, and simulation errors. Trigger on: Meteor, Meteor.js, Meteor 3, MeteorJS, callAsync, useTracker, withTracker, Meteor methods, Meteor publications, Meteor subscriptions, SubsManager, Minimongo, DDP, Mongo.Collection, Meteor.Error, optimistic UI, Fibers migration, meteor async, accounts-express.
OpenTelemetry Transformation Language (OTTL) expert for writing and debugging telemetry transformations in the OpenTelemetry Collector. Use when authoring or reviewing `transform`, `filter`, `tail_sampling` processor configs or `routing` connector configs, debugging OTTL syntax or semantics, transforming traces, metrics, logs, or profiles, or converting data-processing requirements into OTTL statements.
