Routes tasks related to reverse engineering, exploitation, penetration testing, malware, mobile security, firmware analysis, browser automation, documentation, and other security domains to the appropriate specialized skill modules. Use this when a task spans multiple modules or the correct entry point for reverse engineering skills is unclear.
Use the Factorial Code CLI (fcode) for local development and cloud sync — the pull → add → run → push flow, the local webhook/forms server (fcode http), workspace versions and aliases (the stable alias, version_tag), and the workspace config files (process metadata.json, team.json, the three variables files, variables.meta.json). Use when running fcode CLI commands, testing a process locally, syncing to the cloud, managing versions or aliases, overriding an inherited team variable, or configuring a process's webhook or form settings.
Web testing with Playwright, Vitest, k6. E2E/unit/integration/load/security/visual/a11y testing. Use for test automation, flakiness, Core Web Vitals, mobile gestures, cross-browser.
This skill should be used when the user asks to "generate tests", "write unit tests", "analyze test coverage", "scaffold E2E tests", "set up Playwright", "configure Jest", "implement testing patterns", or "improve test quality". Use for React/Next.js testing with Jest, React Testing Library, and Playwright.
Complex DAG testing workflows with debugging and fixing cycles. Use for multi-step testing requests like "test this dag and fix it if it fails", "test and debug", "run the pipeline and troubleshoot issues". For simple test requests ("test dag", "run dag"), the airflow entrypoint skill handles it directly. This skill is for iterative test-debug-fix cycles.
Implement Git hooks using Husky, pre-commit, and custom scripts. Enforce code quality, linting, and testing before commits and pushes.
Use when building blockchain applications or smart contracts across EVM (Solidity), Solana (Anchor/Rust), Cosmos (CosmWasm), and TON, including security/audit workflows, fuzz/invariant testing, upgrades, custody/signing, and backend integration (RPC, indexers, webhooks).
Browser automation, visual testing, and screenshot validation using Playwright MCP server for accelerated web development. Master visual regression testing, automated UI testing, and cross-browser validation.
Use when implementing in-app purchases, StoreKit 2, subscriptions, or transaction handling - testing-first workflow with .storekit configuration, StoreManager architecture, transaction verification, subscription management, and restore purchases for consumables, non-consumables, and auto-renewable subscriptions
Comprehensive backend development guide for Langfuse's Next.js 14/tRPC/Express/TypeScript monorepo. Use when creating tRPC routers, public API endpoints, BullMQ queue processors, services, or working with tRPC procedures, Next.js API routes, Prisma database access, ClickHouse analytics queries, Redis queues, OpenTelemetry instrumentation, Zod v4 validation, env.mjs configuration, tenant isolation patterns, or async patterns. Covers layered architecture (tRPC procedures → services, queue processors → services), dual database system (PostgreSQL + ClickHouse), projectId filtering for multi-tenant isolation, traceException error handling, observability patterns, and testing strategies (Jest for web, vitest for worker).
Testing best practices for the frontend. Emphasizes E2E tests over unit tests, minimal mocking, and testing behavior over implementation details. Use when writing tests or reviewing test code.
