Neo4j graph database development including data modeling and Cypher query optimization

This skill provides the Gen Alpha/brainrot output style transformation rules and vocabulary. It is automatically loaded by the SessionStart hook to transform all Claude responses into Gen Alpha internet slang. Contains comprehensive glossary, transformation patterns, and examples.

Create visual organizational tools (mind maps, task breakdowns, decision trees, kanban boards, project timelines) designed for neurodivergent thinking patterns. Use when users feel overwhelmed, need to break down tasks, navigate decisions, see dependencies, or track current state. Emphasizes compassionate language, realistic time estimates, energy-aware planning, and anti-perfectionism. v3.1 adds colorblind-safe and monochrome accessibility modes.

Documentation-first development methodology. The goal is AI-ready documentation - when docs are clear enough, code generation becomes automatic. Triggers on "Build", "Create", "Implement", "Document", or "Spec out". Version 3.3 adds 10/10 AI Coder requirements with document-type-aware placement (Anti-patterns, Test Cases, Error Handling in implementation docs; Deep Links in all docs).

Builds, tests, and archives Swift packages and Xcode projects for Apple platforms. Use when running xcodebuild, swift build, or swift test commands, discovering schemes and targets, or selecting simulator destinations for iOS, macOS, tvOS, watchOS, or visionOS.

Download YouTube videos, extract English subtitles, translate them to Korean using Claude's own translation capabilities (with video context and web search), and burn Korean subtitles into the video. Use this skill when the user requests Korean subtitle insertion for YouTube videos or asks to translate YouTube content to Korean.

This skill provides safe update capabilities for GitHub SpecKit installations, preserving customizations while applying template updates. **Installation**: Available via plugin (`/plugin marketplace add NotMyself/claude-plugins` then `/plugin install speckit-updater`) or manual Git clone. See [README.md](../../README.md#installation) for details.

System setup, tool information, and AI configuration management for development environments. Use when setting up new machines, explaining available tools (shell-config, ai-rules, wt), managing AI assistant configurations (Claude/Codex/Gemini/OpenCode), checking system configuration, or troubleshooting environment issues. Also triggers when working with configuration files (.json, .toml, .fish, .zsh, .bash), Brewfiles, or installation scripts. Example triggers: "Set up my development environm...

Route code reviews to appropriate council members. Use when reviewing PRs, architecture decisions, or significant code changes that need expert perspective.

ALWAYS use this skill for ALL sudocode spec and issue operations. Use when user mentions "spec", "issue", "ready", "blocked", "implement", "feature", "plan", or "feedback" with sudocode specs and issues. PROACTIVELY use at start of implementation tasks to check ready issues and understand work context. Operations include viewing (show_spec, show_issue, list_issues, list_specs), creating/modifying (upsert_spec, upsert_issue), planning features, breaking down work, creating dependency graphs, a...

Analyze codebase structure, dependencies, and changes. Use when user asks about project structure, where code is located, how files connect, what changed, or before starting any coding task. Provides instant architectural context.

Build scalable WebSocket servers for real-time bidirectional communication. Use when enabling real-time bidirectional communication. Trigger with phrases like "build WebSocket server", "add real-time API", or "implement WebSocket".

Create webhook endpoints with signature verification, retry logic, and payload validation. Use when receiving and processing webhook events. Trigger with phrases like "create webhook", "handle webhook events", or "setup webhook handler".

Generate complete REST API implementations from OpenAPI specifications or database schemas. Use when generating RESTful API implementations. Trigger with phrases like "generate REST API", "create RESTful API", or "build REST endpoints".

Generate gRPC service definitions, stubs, and implementations from Protocol Buffers. Use when creating high-performance gRPC services. Trigger with phrases like "generate gRPC service", "create gRPC API", or "build gRPC server".

Build production-ready GraphQL servers with schema design, resolvers, and subscriptions. Use when building GraphQL APIs with schemas and resolvers. Trigger with phrases like "build GraphQL API", "create GraphQL server", or "setup GraphQL".

Manage API versions with backward compatibility, deprecation notices, and migration paths. Use when managing API versions and backward compatibility. Trigger with phrases like "version the API", "manage API versions", or "handle API versioning".

Manage API throttling policies to protect backend services from overload. Use when controlling API request rates. Trigger with phrases like "throttle API", "control request rate", or "add throttling".

Scan APIs for security vulnerabilities including injection, broken auth, and data exposure. Use when scanning APIs for security vulnerabilities. Trigger with phrases like "scan API security", "check for vulnerabilities", or "audit API security".

Generate client SDKs in multiple languages from OpenAPI specifications. Use when generating client libraries for API consumption. Trigger with phrases like "generate SDK", "create client library", or "build API SDK".

Validate API schemas against OpenAPI, JSON Schema, and GraphQL specifications. Use when validating API schemas and contracts. Trigger with phrases like "validate API schema", "check OpenAPI spec", or "verify schema".

Log API requests with correlation IDs, performance metrics, and security audit trails. Use when auditing API requests and responses. Trigger with phrases like "log API requests", "add API logging", or "track API calls".

Implement sophisticated rate limiting with sliding windows, token buckets, and quotas. Use when protecting APIs from excessive requests. Trigger with phrases like "add rate limiting", "limit API requests", or "implement rate limits".

Build real-time API monitoring dashboards with metrics, alerts, and health checks. Use when tracking API health and performance metrics. Trigger with phrases like "monitor the API", "add API metrics", or "setup API monitoring".
