Data-grid architecture for high-traffic stateful workloads with linear scalability. space-based, data grid, in-memory, linear scaling, high traffic Use when: traffic overwhelms database nodes or linear scalability needed DO NOT use when: data does not fit in memory or simpler caching suffices.

Asynchronous event-based communication to decouple producers/consumers for scalability and resilience. Triggers: event-driven, message queue, pub/sub, asynchronous, decoupling Use when: real-time workloads or multiple subsystems react to same events DO NOT use when: selecting paradigms (use architecture-paradigms first), simple request-response.

Coarse-grained service architecture for deployment independence without microservices complexity. service-based, SOA, coarse-grained services, domain services Use when: teams need deployment independence without microservices complexity DO NOT use when: fine-grained scaling needed - use microservices.

Consult this skill when designing client-server systems or API architectures. Use when traditional web/mobile applications with centralized services, clear separation between client and server responsibilities needed. Do not use when selecting from multiple paradigms - use architecture-paradigms first. DO NOT use when: peer-to-peer dominates - consider dedicated P2P patterns.

Functional Core, Imperative Shell: isolate deterministic logic from side effects for testability. Triggers: functional-core, imperative-shell, pure functions, side-effects, testability Use when: business logic is entangled with I/O or tests are brittle DO NOT use when: simple scripting without complex logic, or performance-critical hot paths where immutability overhead matters.

Single deployable with enforced module boundaries for team autonomy without distributed complexity. Triggers: modular-monolith, module boundaries, single deployment, team autonomy Use when: teams need autonomy without distributed overhead DO NOT use when: already using microservices or system is small.

Record browser sessions using Playwright for web UI tutorials, converts video to GIF.

Evaluate and improve Claude skill quality through auditing. Use when reviewing skill quality, preparing skills for production, or auditing existing skills. Do not use when creating new skills (use modular-skills) or writing prose (use writing-clearly-and-concisely). Use this skill before shipping any skill to production.

Generate or remediate documentation with human-quality writing and style adherence. Use when creating new documentation, rewriting AI-generated content, or applying style profiles. Do not use for slop detection only (use slop-detector) or learning styles (use style-learner).

Guide to effective Claude Code skill authoring using TDD methodology and persuasion principles. Use when creating new skills, improving compliance, or validating quality before deployment. Do not use for evaluating existing skills (use skills-eval) or analyzing architecture (use modular-skills). Follow the Iron Law: write a failing test before writing any skill.

Multi-LLM deliberation for strategic decisions via expert pressure-testing and consensus building. Use for critical, irreversible, or high-stakes architecture choices and conflicts. Skip for trivial or reversible decisions.

Provides KISS, YAGNI, and SOLID code quality principles for clean code, reducing complexity, preventing over-engineering, and improving maintainability.

Use this skill at the START of every session. This is MANDATORY for quota management. location: plugin token_budget: 300. Use when session starts (mandatory), prompt sizes spike, tool calls increase, before long-running analyses or massive context loads. Do not use when context-optimization already handles the scenario. DO NOT use when: simple queries with minimal context.

Quota tracking, threshold monitoring, and graceful degradation for rate-limited API services. quota, rate limiting, usage limits, thresholds.

Orchestrate tutorial generation from VHS tapes and Playwright specs to dual-tone markdown with GIF recording. tutorial update, gif generation, tape recording, update tutorial, regenerate gifs, tutorial manifest Use when: regenerating tutorial GIFs, updating documentation demos, creating tutorials from tape files DO NOT use when: only updating text - use doc-updates.

AWS Bedrock AgentCore comprehensive expert for deploying and managing all AgentCore services. Use when working with Gateway, Runtime, Memory, Identity, or any AgentCore component. Covers MCP target deployment, credential management, schema optimization, runtime configuration, memory management, and identity services.

Configure AWS MCP servers for documentation search and API access. Use when setting up AWS MCP, configuring AWS documentation tools, troubleshooting MCP connectivity, or when user mentions aws-mcp, awsdocs, uvx setup, or MCP server configuration. Covers both Full AWS MCP Server (with uvx + credentials) and lightweight Documentation MCP (no auth required).

AWS Cloud Development Kit (CDK) expert for building cloud infrastructure with TypeScript/Python. Use when creating CDK stacks, defining CDK constructs, implementing infrastructure as code, or when the user mentions CDK, CloudFormation, IaC, cdk synth, cdk deploy, or wants to define AWS infrastructure programmatically. Covers CDK app structure, construct patterns, stack composition, and deployment workflows.

AWS serverless and event-driven architecture expert based on Well-Architected Framework. Use when building serverless APIs, Lambda functions, REST APIs, microservices, or async workflows. Covers Lambda with TypeScript/Python, API Gateway (REST/HTTP), DynamoDB, Step Functions, EventBridge, SQS, SNS, and serverless patterns. Essential when user mentions serverless, Lambda, API Gateway, event-driven, async processing, queues, pub/sub, or wants to build scalable serverless applications with AWS best practices.

AWS cost optimization, monitoring, and operational excellence expert. Use when analyzing AWS bills, estimating costs, setting up CloudWatch alarms, querying logs, auditing CloudTrail activity, or assessing security posture. Essential when user mentions AWS costs, spending, billing, budget, pricing, CloudWatch, observability, monitoring, alerting, CloudTrail, audit, or wants to optimize AWS infrastructure costs and operational efficiency.
