You are an expert in TanStack Query (formerly React Query), the data-fetching and server state management library. You help developers build React applications with automatic caching, background refetching, optimistic updates, pagination, infinite scroll, and offline support — replacing manual `useEffect` + `useState` patterns with declarative, type-safe data fetching hooks.

/cs:cpo-review <plan> — JTBD-driven interrogation of product roadmap, PMF signal, and portfolio focus.

Type-safe routing for React with file-based routes, validated search params, loaders, and automatic code splitting. Use when someone asks to "set up routing for React", "type-safe router", "TanStack Router", "file-based routing", "search params validation", "replace React Router with something type-safe", or "add route-level data loading". Covers file-based routing, search params with Zod, route loaders, code splitting, and layouts.

Build full-stack React apps with TanStack Start. Use when a user asks to create a full-stack React application with type-safe server functions, set up file-based routing with SSR/SSG/SPA modes, build APIs with middleware and validation, implement server-side data fetching with TanStack Router, or deploy to Cloudflare/Netlify/Vercel/Node.

Build powerful data tables with TanStack Table — headless, framework-agnostic table library. Use when someone asks to "build a data table", "TanStack Table", "sortable table", "filterable data grid", "paginated table", "React table", or "headless table library". Covers sorting, filtering, pagination, column resizing, row selection, and virtualization.

Assists with building lightweight cross-platform desktop (and mobile) applications using Tauri. Use when creating small, fast, secure apps with a web frontend and Rust backend that use the system webview instead of bundling Chromium. Trigger words: tauri, rust desktop, system webview, tauri commands, tauri plugins.

Test-driven development with red-green-refactor loop. Use when: user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.

Lead teams effectively using proven frameworks — set clear intent, reduce communication overhead, create psychological safety, and use forcing functions to drive results. Use when: managing teams, improving team collaboration, setting goals and accountability.

Scans codebases for technical debt signals and prioritizes them by business impact. Finds TODO/FIXME/HACK comments, outdated dependencies, code duplication, and correlates with git history to identify high-churn debt hotspots. Use when someone asks about technical debt, code quality audit, refactoring priorities, or maintainability assessment. Trigger words: tech debt, code quality, refactoring, TODOs, maintainability, code health.

Configure Telegraf as a metrics collection agent for infrastructure and application monitoring. Use when a user needs to collect system metrics, set up input plugins for databases and services, configure output to InfluxDB or Prometheus, or build custom metric pipelines.

Export and download Telegram chats, media, and channel content. Use when a user asks to export Telegram chat history, download media from Telegram channels or groups, archive Telegram conversations, backup Telegram messages, extract images or videos from Telegram, bulk download from Telegram channels, scrape Telegram content, or migrate Telegram data. Covers Telegram Desktop export, Telethon-based scripting, and TDLib approaches.

Auto-fill document templates with data. Use when a user asks to create a mail merge, fill templates with data, generate documents from a template, populate placeholders, bulk generate letters or invoices, or auto-fill forms from a spreadsheet. Supports any document format including DOCX, PDF, HTML, and plain text.

Build reliable distributed workflows with Temporal. Use when a user asks to orchestrate microservices, handle long-running workflows, implement saga patterns, build reliable background jobs, or create fault-tolerant distributed systems.

You are an expert in TensorFlow, Google's open-source machine learning framework. You help developers build, train, and deploy neural networks using Keras (TensorFlow's high-level API), custom training loops, TensorFlow Serving for production inference, TFLite for mobile/edge deployment, and TensorFlow.js for browser ML — from prototyping to production-scale distributed training.

Manages cloud infrastructure using Terraform (and OpenTofu). Use when the user wants to write Terraform configurations, provision cloud resources, manage state, create modules, set up multi-environment deployments, import existing infrastructure, debug plan/apply errors, migrate between providers, or implement IaC best practices. Trigger words: terraform, opentofu, infrastructure as code, IaC, tf, hcl, terraform module, terraform state, terraform plan, terraform apply, terraform import, cloud provisioning, AWS terraform, GCP terraform, Azure terraform.

Analyze git diffs and PRs using the codebase knowledge graph to understand impact and risk. Use when: reviewing pull requests, understanding what a diff actually changes, assessing risk of a code change.

You are an expert in Terragrunt, the thin wrapper for Terraform and OpenTofu that provides extra tools for keeping configurations DRY, managing remote state, and orchestrating multi-module deployments. You help platform teams manage large-scale infrastructure across multiple environments and AWS accounts using Terragrunt's hierarchical configuration, dependency management, and before/after hooks.

You are an expert in Tesseract OCR, the most popular open-source optical character recognition engine. You help developers extract text from images, PDFs, and scanned documents using Tesseract's LSTM neural network engine, multi-language support (100+ languages), page segmentation modes, and integration with image preprocessing for maximum accuracy.

Generate unit, integration, and end-to-end tests for existing code. Use when a user asks to write tests, add test coverage, create unit tests, generate integration tests, build e2e tests, improve code coverage, write specs, or add testing to a project. Supports Jest, Vitest, Pytest, Playwright, React Testing Library, and Cypress. Analyzes code to produce meaningful assertions, edge cases, and mock setups.

When the user wants to run integration tests with real dependencies using Docker containers managed by Testcontainers. Also use when the user mentions "testcontainers," "integration testing with Docker," "database integration tests," "containerized tests," or "test with real database." For API mocking without containers, see mockoon or wiremock.
