Coding & Dev Tools

Explains how to define and use tools with the Claude API, including tool schemas, tool choice, and server-side tools for code execution and web search.

Guides contributors through creating pull requests that add or fix skills, with a checklist covering metadata validation, risk labeling, and security disclaimers.

Build modern Angular applications using Signals, Standalone Components, Zoneless change detection, and SSR with hydration.

Write idiomatic C++ code with modern features, RAII, smart pointers, and STL algorithms. Handles templates, move semantics, and performance optimization.

Generates a complete set of favicon files from a source image and updates the project's HTML with the appropriate link tags.

Build cross-platform AI chat interfaces with Makepad using MolyKit, covering async patterns, BotClient integration, and chat widgets.

Answers questions about a code repository by searching and reading source files, then synthesizing answers with inline citations and a key files table.

Provides principles for 2D game development, covering sprite organization, tilemap design, physics, camera systems, and genre-specific patterns.

Provides principles for 3D game development, covering rendering pipelines, shaders, physics, cameras, lighting, and LOD optimization.

Provides a Node.js CLI tool template with Commander.js, interactive prompts, and best practices for building command-line applications.

Provides expert guidance on modern Java 21+ development, covering virtual threads, Spring Boot 3.x, JVM optimization, and cloud-native enterprise patterns.

Scaffolds a Nuxt 3 full-stack project with Vue 3, Pinia, Tailwind, Prisma, and Zod, including setup steps and best practices.

Write idiomatic Ruby code with metaprogramming, Rails patterns, and performance optimization. Specializes in Ruby on Rails, gem development, and testing frameworks.

Runs a structured bug-fix pipeline: scouts evidence, diagnoses root cause, applies minimal fixes, and reviews before committing.

Runs and writes tests for a project, supporting unit, integration, and end-to-end scopes, plus two-pass TDD orchestration with quality-gate checks and regression sweeps.

Generates frontend source code files and a PR description from BA, TechLead, PM, and BE artifacts, following a level-based implementation plan.

Audits code quality against a shared contract, producing structured findings and blocking pipeline phases on critical issues without modifying code.

Creates a machine-readable phased JSON plan bundle from a spec or feature description, producing a compact master manifest plus per-phase step files for resumable execution.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Guides backend development across API design, authentication, security, performance, architecture, and testing, with decision guides and defaults for production-ready systems.

Tests approaches at extreme scales to reveal fundamental limits and strengths hidden at normal scales.

Find a unifying insight that eliminates multiple components, collapsing complexity by abstracting common patterns.

Query a pre-indexed codebase via CLI to understand structure, find symbols, assess change impact, debug failures, and evaluate PR risk.

Manages persistent coding sessions across multiple AI coding engines including Claude Code, Codex, Antigravity, Cursor, and OpenCode, with support for multi-agent councils, cross-session messaging, deep planning, parallel code review, and autonomous workspace iteration.

Operate the Unity Editor through MCP tools and resources, covering scene management, script editing, testing, and automation workflows.

Scaffolds a new ClawBio skill from a JSON/YAML spec or interactively, generating SKILL.md, Python skeleton, tests, and updating the catalog.

Opens a GitHub pull request targeting the main branch using the gh CLI and the repository's PR template, after verifying local checks pass.

Performs deterministic image operations with Python Pillow: resizing, cropping, compositing, format conversion, watermarks, brightness/contrast adjustments, and web optimization.

Creates a conventional commit from staged changes, using an optional user-provided subject.

Quickly refreshes project state when resuming work by reporting git status, recent commits, environment, memory staleness, pending tasks, and red flags.

Generates diagrams and visuals from code or descriptions, routing to specialized tools for hand-drawn, formal, academic, or architectural output.

Scans recently changed code for tech debt: duplicated logic, dead code, magic numbers, deep nesting, and TODOs, then proposes fixes.

Guides a structured feature-development workflow: explore the codebase with subagents, draft a plan for approval, implement step by step, verify with parallel checks, and record conventions.

Runs a test-driven rendering loop for Copier templates, writing E2E assertions first and iterating until every flavor renders cleanly before committing.

Guides the creation of well-structured Claude Code skills and slash commands, covering skill types, scope, frontmatter settings, and file organization.

Runs a structured code review using four parallel subagents covering style, correctness, security, and performance, then synthesizes findings by severity and gives an approve/needs-changes recommendation.
