Store and search vector embeddings in PostgreSQL with pgvector — no separate vector database needed. Use when someone asks to "vector search in Postgres", "store embeddings", "pgvector", "similarity search", "RAG with Postgres", "semantic search in existing database", or "add AI search to my app without a separate vector DB". Covers vector columns, indexing (IVFFlat, HNSW), similarity search, and integration with ORMs.

Phoenix is an Elixir web framework built on the BEAM VM for fault-tolerant, real-time applications. It features LiveView for interactive UIs without JavaScript, channels for WebSockets, and Ecto for database access with compile-time query validation.

Pinecone is a managed vector database for AI and machine learning applications. Learn to create indexes, upsert embeddings, query by similarity, use namespaces and metadata filtering for semantic search and RAG pipelines.

Log in Node.js with Pino. Use when a user asks to add structured logging, improve logging performance, configure log levels, format logs for production, or replace console.log with proper logging.

You are an expert in PixiJS, the fastest 2D rendering engine for the web. You help developers build games, interactive visualizations, animated ads, creative coding projects, and rich UI effects using PixiJS's WebGL-first renderer with automatic Canvas fallback — handling sprites, text, filters, masks, blend modes, and custom shaders at 60fps with hundreds of thousands of objects.

Expert guidance for Plasmo, the framework for building browser extensions with React, TypeScript, and modern tooling. Helps developers create Chrome and Firefox extensions with content scripts, background workers, popup UIs, and messaging — all with hot reload and zero webpack config.

Write and maintain end-to-end tests with Playwright. Use when someone asks to "add e2e tests", "test my web app", "set up Playwright", "write browser tests", "test login flow", "visual regression testing", "test across browsers", or "automate UI testing". Covers test setup, page objects, authentication, API mocking, visual comparisons, and CI integration.

Send transactional and marketing emails with Plunk. Use when a user asks to send emails from an app, set up email automation, create drip campaigns, or use a simple open-source email platform.

Assists with building backends using PocketBase, a single-binary backend with embedded SQLite, real-time subscriptions, file storage, and authentication. Use when creating MVPs, prototyping APIs, configuring collections, or setting up auth flows. Trigger words: pocketbase, backend, sqlite, real-time, single binary, collections, pb.

Manage Python projects with Poetry. Use when a user asks to manage Python dependencies, create virtual environments, publish packages to PyPI, handle dependency resolution, or set up a Python project structure.

You are an expert in Polar, the monetization platform built for developers and open-source maintainers. You help developers add payments, subscriptions, product sales, license keys, and sponsorships to their projects with a developer-first API, webhooks, and embeddable components — replacing Stripe integration complexity with purpose-built tools for software monetization.

Generate PDF documents programmatically with PDFKit — add text, images, vector graphics, tables, headers/footers, and custom fonts. Use when tasks involve creating invoices, reports, certificates, or any structured PDF output from application data in Node.js.

Run AI-powered penetration testing with PentAGI. Use when a user asks to automate security testing, set up autonomous pentesting, deploy an AI-driven vulnerability scanner, build a self-hosted security testing platform, or conduct penetration tests with LLM-powered agents.

Review code for performance issues and optimization opportunities. Use when someone needs to check for N+1 queries, unnecessary re-renders, memory leaks, inefficient algorithms, missing indexes, or bundle size regressions. Trigger words: performance review, slow query, N+1, memory leak, bundle size, latency, optimization, re-render, Big O.

You are an expert in PGlite, the lightweight WASM Postgres build that runs in the browser, Node.js, and Deno. You help developers embed a full Postgres instance (with extensions like pgvector, PostGIS) in client-side apps, Electron, React Native, and serverless functions — providing real SQL with JSONB, full-text search, and vector similarity search at ~3MB compressed, without a server.

You are an expert in Phaser, the fast and feature-rich HTML5 game framework for making 2D games that run in web browsers and mobile devices. You help developers build arcade games, puzzle games, RPGs, platformers, and roguelikes using Phaser's scene system, physics engines (Arcade and Matter.js), sprite animations, tilemaps, tweens, particle effects, and input handling — with TypeScript support and Vite for modern development workflow.

Set up, configure, and manage PicoClaw — an ultra-lightweight personal AI assistant built in Go. Use when the user mentions "picoclaw," "pico claw," "lightweight AI assistant," or wants to deploy a personal AI agent on low-resource hardware (Raspberry Pi, RISC-V boards). Covers installation, LLM provider configuration, messaging gateway setup (Telegram, Discord, Slack, LINE, DingTalk), scheduled tasks, heartbeat, workspace layout, security sandbox, and Docker deployment.

You are an expert in Pinia, the official state management library for Vue.js. You help developers build Vue applications with type-safe stores, Composition API support, getters (computed), actions (sync and async), plugins, SSR compatibility, and Vue DevTools integration — replacing Vuex with a simpler, fully typed, modular store system.

You are an expert in Pipedream, the workflow automation platform built for developers. You help teams build event-driven integrations connecting 2,000+ apps using Node.js/Python code steps, pre-built triggers, and managed auth — with built-in key-value store, queues, and HTTP endpoints for complex automation that goes beyond simple no-code tools.

Expert guidance for PlanetScale, the serverless MySQL platform built on Vitess (the database clustering system powering YouTube). Helps developers set up databases with Git-like branching for schema changes, non-blocking schema migrations, and connection pooling for serverless environments.
