DevOps

Autonomously build and test web applications using Playwright MCP server. Enables iterative development with automatic verification - make changes, run the app, visually verify, check for errors, and iterate. Use when building websites, debugging UI issues, or implementing features that need visual verification.

Write clear, developer-focused documentation including README files, API docs, architecture decision records, code comments, and user guides. Use for documentation tasks, markdown files (.md), or improving existing docs.

Core design principles for creating distinctive, beautiful UIs with technical excellence.Combines creative direction with practical foundation for memorable, accessible interfaces.Use when building UI without specific design specs (Figma, screenshots, design files):- Creating landing pages, home pages, marketing pages from scratch- Building web apps, dashboards, admin panels without design- Choosing design system: typography, colors, spacing, visual hierarchy- Need to propose complete design (fonts, colors, layout, spacing)- Building distinctive UIs that avoid generic AI aestheticsKeywords: landing page, design system, typography, colors, spacing, visual hierarchyTwo-part approach:1. Creative Direction: Choose aesthetic tone (minimal, bold, elegant, playful)2. Technical Foundation: Spacing scales, typography specs, WCAG contrast, hierarchyGoal: Create UIs that are BOTH beautiful (distinctive, memorable) AND correct (accessible, consistent, professional).

Comprehensive guide to Claude Code's extensibility features including subagents, skills, plugins, commands, hooks, MCP servers, permissions, and automation. Use when the user asks about Claude Code features, capabilities, customization, extensibility, how to extend Claude Code, or automation workflows.

Maintain a single deployable artifact while enforcing strong internal boundaries between modules.

Build and deploy Coditect modules (backend, frontend+Theia combined) to GCP using Cloud Build. Use when deploying to GKE, troubleshooting builds, or optimizing build times.

Implement comprehensive input validation on server-side with complementary client-side validation for user experience, using allowlists, type checking, and sanitization to prevent injection attacks. Use this skill when validating user inputs, form data, API requests, file uploads, query parameters, or any external data entering the application. Apply this skill when implementing server-side validation as the primary security layer, adding client-side validation for immediate user feedback, validating data types and formats, checking ranges and required fields, sanitizing inputs to prevent SQL injection and XSS attacks, using allowlists over blocklists, providing field-specific error messages, or enforcing business rules at appropriate application layers. This skill ensures validation happens at all entry points consistently, security is never dependent on client-side checks alone, users receive helpful immediate feedback, and data integrity is maintained through multiple layers of validation.

Data validation and pipeline testing utilities for ML training projects. Validates datasets, model checkpoints, training pipelines, and dependencies. Use when validating training data, checking model outputs, testing ML pipelines, verifying dependencies, debugging training failures, or ensuring data quality before training.

Safe deployment workflow for Fly.io and infrastructure changes. Use before ANY deployment, config modification, or infrastructure change. Prevents panic-driven debugging and production incidents.

Post-PRD project initialization skill for the /initialize-project command.Guides constitution customization, agent training, and workflow configurationbased on completed Product Requirements Document. Ensures framework istailored to specific project needs while maintaining constitutional compliance.
