Design

Run and debug a repo verification pipeline (`./verify.sh --ui=false` or equivalent), including stage selection and opt-in E2E tiers.

Workload Identity Federation implementation guide. GKE setup, IAM bindings, ServiceAccount configuration, migration from service account keys, and troubleshooting patterns.

This skill should be used when the user asks to "verify reproducibility", "confirm the results", "prove it's reproducible", or as Phase 5 of the /ds workflow before claiming completion. Checks reproducibility and requires user acceptance.

core.async.flow provides a declarative framework for building process flows with strict separation of application logic from topology, execution, and lifecycle management. Use when building multi-process systems, data pipelines, or when you need coordinated lifecycle management and error handling across communicating processes.

Design new API endpoints following the Hoon-Rust-HTTP pattern used in this NockApp. Use when adding endpoints, modifying SNARK structure, extending the API, or implementing new features.

Comprehensive mobile DevOps workflow that orchestrates mobile application development, CI/CD for mobile, app store deployment, and mobile device testing. Handles everything from mobile app build automation and testing to app store submission, monitoring, and mobile-specific DevOps practices.

Evaluate API surfaces against internal guidelines and external examples in any language.

World-class prompt engineering skill for LLM optimization, prompt patterns, structured outputs, and AI product development. Expertise in Claude, GPT-4, prompt design patterns, few-shot learning, chain-of-thought, and AI evaluation. Includes RAG optimization, agent design, and LLM system architecture. Use when building AI products, optimizing LLM performance, designing agentic systems, or implementing advanced prompting techniques.

Use this skill whenever the user wants to design, refactor, or optimize data fetching and caching in a Next.js (App Router) + TypeScript project, including server components, route handlers, server actions, cache modes, revalidation, and selective client-side fetching.

This skill should be used when working with browser-rendered artifacts (i.e. Bun, React/React Native) to proactively validate that development work on localhost is being built appropriately and to support debugging browser-rendered content. Use this skill after making frontend changes to verify the output visually.

Generate production-ready Workscript workflow JSON files for the Workscript Agentic Workflow Engine with built-in defensive guards and complexity detection. Use when asked to create workflows, automations, data pipelines, or generate workflow JSON. IMPORTANT - For complex requests that would result in deeply nested or overly complex workflows, this skill will STOP and suggest developing new custom nodes first using /new-node, then return to create a simpler, more linear workflow. All generated workflows include data validation (validateData node) for structured JSON outputs, input guards, array length checks, and error handling edges. Fetches up-to-date node documentation from the Reflection API when available. Outputs validated .json files to the sandbox prompts folder. Also suitable for Claude Code subagents needing to compose workflows programmatically.

Build n8n automation workflows using MCP tools. Use when creating workflows, configuring nodes, validating configurations, deploying templates, or integrating n8n with Rails apps. Supports Israeli market (Hebrew, WhatsApp Business, NIS payments).

Using PolicyEngine web apps to analyze tax and benefit policy impacts - for users of policyengine.org

Brand-specific PowerPoint building with python-pptx. Supports multiple templates, custom layouts, and programmatic slide generation.

Validate and lint structured data files (YAML, JSON, TOML) for consistency, required fields, syntax errors, and schema compliance.

Implement domain-driven design (DDD) and clean architecture patterns in ASP.NET Core Web APIs. Use this skill when building or refactoring backend services that need strategic domain modeling, tactical DDD patterns (entities, value objects, aggregates, domain events, repositories), and clean architecture layers (domain, application, infrastructure, presentation). Follows principles from Eric Evans' "Domain-Driven Design" and Robert C. Martin's "Clean Architecture".

Generates a technical blog post from code implementation. Use when asked to write a blog post about a feature, explain an implementation for a blog, document code as a blog article, or create technical content from source code. Triggers on phrases like "write a blog post about", "turn this into a blog", "create a technical article", or "explain this for a blog".

Analyze fit between job requirements and background using lexicons - identifies gaps, develops reframing strategies, creates cover letter plan

Write TypeScript for Web Components and Node.js with strict typing. Use when adding types to JavaScript projects, building type-safe APIs, or creating generic utilities.

Use for Python development requiring async programming, type system expertise, testing patterns, or performance optimization.
