Expert guidance for product strategy, helping product leaders define product vision, craft positioning, analyze competitive landscapes, choose pricing models, and build outcome-driven roadmaps. Applies frameworks from Marty Cagan (Empowered), April Dunford (Obviously Awesome), Gibson Biddle (DHM Model), and Reforge.

Apply proven mental models to boost personal and team productivity — focus techniques, decision frameworks, and task management principles. Use when: improving personal productivity, making better decisions faster, coaching teams on effective work habits.

Configure Prometheus Alertmanager for alert routing, grouping, silencing, and notification delivery. Use when a user needs to set up alert receivers (Slack, PagerDuty, email), define routing trees, manage silences and inhibition rules, or troubleshoot alert delivery pipelines.

Design, test, and iterate on AI prompts systematically using structured evaluation criteria. Use when building AI features, optimizing agent instructions, comparing prompt variants, or evaluating output quality across edge cases. Trigger words: prompt engineering, prompt testing, eval, LLM evaluation, prompt comparison, A/B test prompts, prompt optimization, system prompt, instruction tuning.

Test and evaluate LLM prompts systematically with Promptfoo — open-source eval framework. Use when someone asks to "test my prompts", "evaluate LLM output", "Promptfoo", "prompt regression testing", "compare LLM models", "LLM evaluation framework", or "benchmark prompts against test cases". Covers test cases, assertions, model comparison, red-teaming, and CI integration.

Create compelling business proposals that win deals and partnerships. Use when a user asks to write a proposal, draft a business proposal, create a project proposal, prepare a bid, write a pitch document, or generate a partnership proposal. Produces structured, persuasive documents ready for client delivery.

You are an expert in Protocol Buffers (protobuf), Google's language-neutral binary serialization format. You help developers define data schemas with `.proto` files, generate typed code for multiple languages, build efficient APIs with gRPC, and handle schema evolution with backward/forward compatibility — achieving 3-10x smaller payloads and 20-100x faster serialization than JSON.

Assists with defining and managing cloud infrastructure using Pulumi with TypeScript, Python, Go, or C#. Use when provisioning AWS, GCP, Azure, or Kubernetes resources with real programming languages instead of HCL. Trigger words: pulumi, infrastructure as code, iac, pulumi up, pulumi stack, cloud infrastructure, component resource.

Automate browsers and scrape dynamic websites with Puppeteer. Use when a user asks to scrape JavaScript-rendered pages, automate browser interactions, take screenshots of web pages, generate PDFs from URLs, test web UIs, fill out forms programmatically, crawl SPAs, extract data from dynamic sites, automate login flows, or build web scrapers that need a real browser. Covers headless Chrome, page navigation, DOM interaction, network interception, screenshots, PDF generation, and stealth techniques.

You are an expert in Pusher Channels, the hosted real-time messaging platform. You help developers add live features to applications using pub/sub channels, presence channels for online status, private channels with auth, client events for peer-to-peer, webhooks, and batch triggers — enabling real-time notifications, live dashboards, chat, and collaborative features without managing WebSocket infrastructure.

Validate and serialize data with Pydantic. Use when a user asks to validate API inputs, parse JSON/env config, define data models in Python, serialize objects, or implement data validation with type hints.

Test Python code with pytest. Use when a user asks to write unit tests, set up test fixtures, mock dependencies, run async tests, measure coverage, or implement test-driven development in Python.

Assists with building, training, and deploying neural networks using PyTorch. Use when designing architectures for computer vision, NLP, or tabular data, optimizing training with mixed precision and distributed strategies, or exporting models for production inference. Trigger words: pytorch, torch, neural network, deep learning, training loop, cuda.

You are an expert in Qdrant, the high-performance vector search engine written in Rust. You help developers build semantic search, RAG retrieval, recommendation systems, and anomaly detection with billion-scale vector collections, advanced filtering, multi-vector support, and hybrid search — providing sub-millisecond query latency with rich payload filtering that other vector DBs can't match.

Integrate with the QuickBooks Online API via OAuth2 to manage invoices, bills, expenses, customers, vendors, and pull financial reports. Use when: connecting SaaS apps to QuickBooks, automating financial data pipelines, syncing transactions, or building accounting integrations for small business clients.

Qwik is a resumable web framework that delivers instant-loading applications by eliminating hydration. It serializes application state on the server and lazily loads JavaScript on interaction, making it ideal for edge deployment.

Build messaging systems with RabbitMQ — queues, exchanges, routing, dead-letter queues, delayed messages, priority queues, and RPC patterns. Use when tasks involve task queues, background job processing, inter-service communication, request-reply patterns, or reliable message delivery with acknowledgments.

Build accessible UI primitives with Radix UI. Use when creating accessible dropdowns, dialogs, popovers, tabs, tooltips, or building a design system with unstyled, composable components.

Expert guidance for Ragas, the framework for evaluating Retrieval-Augmented Generation pipelines. Helps developers measure and improve the quality of their RAG systems across retrieval accuracy, answer faithfulness, and response relevance.

Ruby on Rails is a full-stack web framework following convention over configuration. It provides ActiveRecord ORM, Action Controller, Action View templates, Action Cable for WebSockets, and generators for rapid application development.
