Claude Skills

Infrastructure-as-Code specialist for Terraform, AWS, Azure, and serverless architectures. Use when setting up cloud infrastructure, writing Terraform modules, or deploying to AWS Lambda/Vercel/Cloudflare. Covers VPC configuration, container orchestration, and CI/CD pipeline infrastructure.

Code navigation with LSP. When user says "find references", "go to definition", "where defined", "show type", "list symbols", "what uses", or "who calls" - use native LSP tools if available, otherwise fall back to specweave lsp commands.

Intelligent multi-project specification splitting that maps user stories to correct projects (FE, BE, MOBILE, INFRA). Use when working with multiple JIRA/GitHub projects, microservices architecture, or brownfield projects with multiple teams. Analyzes content and tech stack for automatic classification.

Performance engineering for web applications, databases, and distributed systems optimization. Use for analyzing bottlenecks, implementing caching strategies, or improving Core Web Vitals. Covers profiling, load testing, bundle optimization, and database query performance tuning.

Product roadmap and feature prioritization expert with RICE, MoSCoW, and Kano frameworks. Use when planning product roadmaps, prioritizing features across increments, or defining success metrics and KPIs. Covers ROI analysis, stakeholder communication, and quarterly planning.

Real-time security pattern detector based on Anthropic's official security-guidance plugin. Use proactively when writing code to detect command injection, XSS, unsafe deserialization, and dynamic code execution risks. Identifies dangerous patterns BEFORE they're committed.

Serverless platform selection expert for AWS Lambda, Azure Functions, GCP Cloud Functions, and Firebase. Use when choosing between serverless platforms, evaluating cold start requirements, or designing event-driven architectures. Considers project scale (pet project vs enterprise), workload patterns, and cost optimization.

Detects when user reports issues with recently completed work and suggests reopening relevant tasks or increments. Use when reporting bugs, regressions, or problems with recently finished features. Scans completed work from last 7 days and provides relevance-scored suggestions while checking WIP limits.

Master TDD orchestrator for strict red-green-refactor discipline, multi-agent test-driven workflows, and TDD intent detection. Use when implementing TDD across complex features, coordinating test and implementation agents, enforcing TDD cycle discipline, or wanting to write tests first. Covers modern TDD practices, test isolation, quality gates, and TDD education.

Technical lead bridging architecture and implementation for code quality and guidance. Use when reviewing code, refactoring for maintainability, or breaking features into implementation tasks. Covers design patterns, SOLID principles, code organization, and technical debt management.

Generate tasks.md with embedded test plans in BDD format, one user story at a time to prevent crashes. Use for test-first task planning where each task includes Given/When/Then scenarios. Produces implementation tasks with inline test specifications.

LLM-native translation skill that uses the current session for zero-cost SpecWeave content translation. Use when translating CLI messages, templates, documentation, or living docs to other languages. Supports multilingual output and internationalization workflows.

Spec-driven brainstorming and product discovery expert. Helps teams ideate features, break down epics, conduct story mapping sessions, prioritize using MoSCoW/RICE/Kano, and validate ideas with lean startup methods. Activates for brainstorming, product discovery, story mapping, feature ideation, prioritization, MoSCoW, RICE, Kano model, lean startup, MVP definition, product backlog, feature breakdown.

Automated data visualization for EDA, model performance, and business reporting. Activates for "visualize data", "create plots", "EDA", "exploratory analysis", "confusion matrix", "ROC curve", "feature distribution", "correlation heatmap", "plot results", "dashboard". Generates publication-quality visualizations integrated with SpecWeave increments.

Implement GitOps workflows with ArgoCD and Flux for automated, declarative Kubernetes deployments with continuous reconciliation. Use when implementing GitOps practices, automating Kubernetes deployments, or setting up declarative infrastructure management.

Security engineer for vulnerability assessment, penetration testing guidance, and secure code review. Use for OWASP Top 10 checks, threat modeling, or security architecture review. Covers authentication flaws, injection vulnerabilities, access control, and compliance requirements.

Test-Driven Development (TDD) expertise covering red-green-refactor cycle, behavior-driven development, test-first design, refactoring with confidence, TDD best practices, TDD workflow, unit testing strategies, mock-driven development, test doubles, TDD patterns, SOLID principles through testing, emergent design, incremental development, TDD anti-patterns, and production-grade TDD practices. Activates for TDD, test-driven development, red-green-refactor, test-first, behavior-driven, BDD, refactoring, test doubles, mock-driven, test design, SOLID principles, emergent design, incremental development, TDD workflow, TDD best practices, TDD patterns, Kent Beck, Robert Martin, Uncle Bob, test-first design.

Comprehensive feature engineering for ML pipelines: data quality assessment, feature creation, selection, transformation, and encoding. Activates for "feature engineering", "create features", "feature selection", "data preprocessing", "handle missing values", "encode categorical", "scale features", "feature importance". Ensures features are production-ready with automated validation, documentation, and integration with SpecWeave increments.

Python backend developer for FastAPI, Django, and Flask. Use when building Python APIs, REST endpoints, or data processing services.
