blueprintkit
Complete project planning and execution framework. Automatically includes all 14 planning sections (planning/0-Master-Index.md through planning/13-Lessons-Learned-Continuous-Improvement.md) plus all 9 Claude Skills (tech-stack-selector, architecture-decisions, code-standards-enforcer, ci-cd-pipeline-builder, agile-executor, project-risk-identifier, automation-orchestrator, webapp-testing, web-artifacts-builder). When installed, all planning templates and execution skills are immediately available.
26core-engineering
Object-oriented design and Core Engineering principles for AI agents and developers. Use when the user asks about OOP (four pillars), SOLID, encapsulation, abstraction, inheritance, polymorphism, Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion, composition over inheritance, DRY, KISS, YAGNI, Law of Demeter, or association vs aggregation vs composition. Includes how each principle looks and example code.
16erc8004-agent-creator
Usage and installation for create-8004-agent (ERC-8004 / 8004 AI agent scaffold). Use when the user asks how to create an ERC-8004 or 8004 agent, how to install or run create-8004-agent, what wizard options mean, which chains are supported, what gets generated, or how to configure and register the generated project (env, npm run register, start:a2a, start:mcp). Covers EVM (Ethereum, Base, Polygon, Monad) and Solana.
11co-star-ui
CO-STAR UI Creator for React/Next.js: structured prompting to build or integrate UI (components, pages, design systems) or to create custom CO-STAR prompts. Use when the user wants to add hero sections, dashboards, design tokens, shadcn/Magic UI/Aceternity integration, Newsprint design system, or to draft their own CO-STAR prompt (Context, Objective, Style, Tone, Audience, Response). Always run discovery questions first, then plan, then implementation.
9context-engineering
Context Engineering patterns for AI development and prompting. Use when the user wants to reduce tokens, avoid lost-in-the-middle, and structure prompts using Skeleton-of-Thought, token-efficient diff updates, XML tagging, symbolic variables, negative constraints, or LLMBundle-style context packaging.
8agent-hub
Plug-and-play orchestration skill. User states a goal in natural language; the model runs commands/agent-hub.md (dispatcher), classifies work via agent/operating-model.md, then opens only the matching command or architecture doc (map, architect, memory, recovery, verify, next-pass, or one NN-layer). Layered docs for intent, policy, context, planning, routing, delegation, execution, MCP/tool boundaries, verification, memory, recovery, observability, human gates, release. Use for repo orchestration reviews, boundary work, memory/recovery design, permission-sensitive refactors.
