Build Redis caching, request limits, locks that coordinate multiple workers, and messaging. Use concrete implementation patterns to choose data structures, set key expiration, manage connections, and review common production pitfalls.
Set up Plankton hooks in Claude Code to format and lint files after each edit. Route remaining violations to Claude for fixes, verify the results, and protect linter settings from changes that weaken checks.
Build and review React 18/19 components with guidance on state management, data fetching, forms, loading states, and error handling. It also covers keyboard access and how to divide components between server and browser execution.
Write, review, and refactor Rust code using established conventions for ownership, error handling, type design, and concurrency. It guides safer implementations, avoids unnecessary copying, and organizes modules with a limited public interface.
Coordinate bug fixes by assigning each phase to an appropriate ECC agent. First reproduce the problem with a failing test, then fix it, review the changes, and request approval before committing.
Turn a design or requirements document into a working MVP, a minimal product, through small end-to-end feature slices. It coordinates scaffolding, repeated generation and evaluation, reviews, and approval gates, with separate commits for the scaffold and each slice.
Review MySQL and MariaDB database designs and production problems, including slow queries, locking, connection pools, and replica delays. Get concrete SQL or code changes and a validation plan that accounts for differences between engines and versions.
Build interactive animations in React or Next.js, including draggable elements, swipe gestures, animated text, SVG line drawing, and loading indicators. Guides API selection and multi-step animation sequences, with touch testing and cleanup practices.
Measure and improve delays in realtime dashboards, data feeds, queues, and caches. Track response times, data age, and waiting work separately, then verify that changes improve the actual behavior of a deployed system.
Build and review Nuxt 4 applications with consistent server and browser rendering. Guide data fetching, page rendering and caching rules, and deferred loading to address rendering mismatches and improve performance.
Implement and review Ethereum hashing in JavaScript or TypeScript using Keccak-256. Learn which library helpers to use and avoid confusing it with Node's SHA3 when calculating function identifiers, signature hashes, storage locations, or addresses.
Find Laravel packages for specific features through LaraPlugins.io MCP, a connection to its package search tools. Check maintenance indicators, release history, and Laravel/PHP compatibility to compare candidates before adding a package to a project.
Build and maintain MCP servers that let AI assistants use tools, read data, and access reusable prompts. Covers Node/TypeScript implementation, input validation, transport choices for local or remote clients, and registration or connection troubleshooting.
Change an existing feature that works but needs different behavior. The skill updates tests to reflect the new requirements, adjusts the implementation, and coordinates review with approval checkpoints before committing the changes.
Coordinate code refactoring, restructuring code while preserving its behavior. Check existing tests before changes, work in small steps, review the result, and pause for approval of the plan and before committing.
Build and review Laravel web applications and APIs with clear separation of responsibilities. Covers Eloquent database models, input validation, consistent API responses, background jobs, events, and caching, helping organize application logic and data access.
Operate and extend NanoClaw, an interactive command environment with sessions stored in Markdown. Resume, branch, search, compact, and export sessions, or switch models and load skills through slash commands.
Build a shared animation foundation for React and Next.js with motion/react. Define reusable timing and spring settings, respect reduced-motion preferences, adapt to device performance, and align initial animation states with server-rendered content.
Add animations to React and Next.js interfaces, including buttons, modals, notifications, page transitions, and scrolling content. Uses shared motion settings and reusable patterns for elements entering, leaving, moving, or changing size.
Guides implementation of signup confirmations, password resets, and other application emails through Mailtrap. Covers API authentication, verified sending domains, separate testing environments that capture messages without delivery, and handling failed send requests.
Prepare a private project for public release by creating a separate copy, removing sensitive information, checking for remaining risks, and generating documentation, setup scripts, and license files for review before publishing.
Coordinate feature work, bug fixes, refactoring, and MVP development through shared phases scaled to the change. Related operation skills use this workflow to delegate research, planning, test-first implementation, review, and commits with human approval checkpoints.
Write, review, and refactor Kotlin code using established conventions. Covers safe handling of missing values, immutable data, coroutines for asynchronous work, and type-safe configuration builders, helping keep application code readable and maintainable.
Guide development and debugging in Next.js 16 and later using Turbopack, a tool that bundles application code. Review slow startup, live updates, caching, webpack alternatives, bundle analysis, and version-specific proxy file naming.
