End-to-end guide for creating React components in AgenticFleet's frontend, from design tokens through Tailwind styling, shadcn/ui integration, state management, to testing.

Active context curation to fight context rot. Curates what goes into limited context window from constantly evolving information universe. 39% improvement, 84% token reduction.

Design skills as modular building blocks for predictable token usage.Triggers: skill design, skill architecture, modularization, token optimization,skill structure, refactoring skills, new skill creation, skill complexityUse when: creating new skills that will be >150 lines, breaking down complexmonolithic skills, planning skill architecture, refactoring overlapping skills,reviewing skill maintainability, designing skill module structureDO NOT use when: evaluating existing skill quality - use skills-eval instead.DO NOT use when: writing prose for humans - use writing-clearly-and-concisely.DO NOT use when: need improvement recommendations - use skills-eval.Use this skill BEFORE creating any new skill. Check even if unsure.

Gemini CLI delegation workflow implementing delegation-core for Google's Gemini models.Triggers: gemini cli, gemini delegation, google gemini, 1M context, large file analysis,gemini batch, gemini summarization, gemini extractionUse when: delegation-core selected Gemini, need Gemini's 1M+ token context window,batch processing or large document summarization requiredDO NOT use when: deciding which model to use - use delegation-core first.DO NOT use when: gemini CLI not installed or authenticated.Consult this skill when implementing Gemini-specific delegation workflows.

Context-aware progressive module loading with hub-and-spoke pattern for token optimization.Triggers: progressive loading, lazy loading, hub-spoke, module selectionUse when: optimizing skill loading or reducing upfront context usage

Authentication patterns for external services: API keys, OAuth, token management, verification.Triggers: authentication, API keys, OAuth, token management, credentialsUse when: integrating external services or implementing authentication flows

Minimize token usage through conservative prompting, work delegation,and quota tracking.Triggers: token usage, quota, token limits, prompt size, token conservation,usage tracking, delegation, context compression, token budgetUse when: session starts (mandatory), prompt sizes spike, tool calls increase,before long-running analyses or massive context loadsDO NOT use when: context-optimization already handles the scenario.DO NOT use when: simple queries with minimal context.Use this skill at the START of every session. This is MANDATORY for quota management.

Monitor and optimize CPU/GPU usage with load measurement and cost-effectivevalidation strategies.Triggers: CPU usage, GPU usage, performance, load monitoring, build performance,training, resource consumption, test suite, compilationUse when: session starts (auto-load with token-conservation), planning buildsor training that could pin CPUs/GPUs for >1 minute, retrying failed resource-heavy commandsDO NOT use when: simple operations with no resource impact.DO NOT use when: quick single-file operations.Use this skill BEFORE resource-intensive operations. Establish baselines proactively.

Standardized pytest configuration for plugin development with shared test patterns.Triggers: pytest configuration, conftest, fixtures, test setupUse when: setting up pytest for plugin development or creating fixtures

Reduce context usage with MECW principles (keep under 50% of total window).Triggers: context pressure, token usage, MECW, context window, optimization,decomposition, workflow splitting, context management, token optimizationUse when: context usage approaches 50% of window, tasks need decomposition,complex multi-step operations planned, context pressure is highDO NOT use when: simple single-step tasks with low context usage.DO NOT use when: already using mcp-code-execution for tool chains.Use this skill BEFORE starting complex tasks. Check context levels proactively.

Transform tool-heavy workflows into MCP code execution patterns for token savings and optimized processing.Triggers: MCP, code execution, tool chain, data pipeline, tool transformation, batch processing, workflow optimizationUse when: >3 tools chained sequentially, large datasets (>10k rows), large files (>50KB), context usage >25%DO NOT use when: simple tool calls that don't chain.DO NOT use when: context pressure is low and tools are fast.Use this skill BEFORE building complex tool chains. Optimize proactively.

Evaluate and improve Claude skill quality through auditing.Triggers: skill audit, quality review, compliance check, improvement suggestions,token usage analysis, skill evaluation, skill assessment, skill optimization,skill standards, skill metrics, skill performanceUse when: reviewing skill quality, preparing skills for production, auditingexisting skills, generating improvement recommendations, checking compliancewith standards, analyzing token efficiency, benchmarking skill performanceDO NOT use when: creating new skills from scratch - use modular-skills instead.DO NOT use when: writing prose for humans - use writing-clearly-and-concisely.DO NOT use when: need architectural design patterns - use modular-skills.Use this skill BEFORE shipping any skill to production. Check even if unsure.

Reference for Splitrail's core data types. Use when working with ConversationMessage, Stats, DailyStats, or other type definitions.

Build responsive, mobile-first layouts using fluid containers, flexible units, media queries, and touch-friendly design that works across all screen sizes. Use this skill when creating or modifying UI layouts, responsive grids, breakpoint styles, mobile navigation, or any interface that needs to adapt to different screen sizes. Apply when working with responsive CSS, media queries, viewport settings, flexbox/grid layouts, mobile-first styling, breakpoint definitions (mobile, tablet, desktop), touch target sizing, relative units (rem, em, %), image optimization for different screens, or testing layouts across multiple devices. Use for any task involving multi-device support, responsive design patterns, or adaptive layouts.

Write consistent, maintainable CSS following the project's methodology (Tailwind, BEM, utility classes, CSS modules) with design system adherence and performance optimization. Use this skill when writing or modifying styles, CSS files, utility classes, CSS-in-JS, styled components, or any styling code. Apply when working with .css, .scss, .module.css files, Tailwind utility classes, styled-components, CSS modules, design tokens (colors, spacing, typography), framework-specific styling approaches, optimizing CSS for production, implementing CSS purging or tree-shaking, or avoiding style overrides. Use for any task involving visual styling, layout styling, design system implementation, or CSS organization.

Design and implement RESTful API endpoints following REST principles with proper HTTP methods, status codes, and resource-based URLs. Use this skill when creating or modifying API endpoints, route handlers, controllers, or API configuration files. Apply when working on REST API design, endpoint implementations, API versioning, request/response handling, HTTP method routing (GET, POST, PUT, PATCH, DELETE), query parameter filtering, API rate limiting, or any file that defines API routes such as routes.py, api.js, controllers/, endpoints/, or API documentation files.

Use when creating or improving Claude Code agents. Expert guidance on agent file structure, frontmatter, persona definition, tool access, model selection, and validation against schema.

Design reusable, composable UI components following single responsibility principle with clear interfaces, encapsulation, and minimal props. Use this skill when creating or modifying frontend components in any framework (React, Vue, Svelte, web components) or component files. Apply when working with .jsx, .tsx, .vue, .svelte files in component directories (components/, src/components/, ui/, lib/), defining component props and interfaces, implementing component composition patterns, managing component-level state, creating reusable UI elements (buttons, forms, cards, modals), documenting component APIs, or refactoring components for better reusability and maintainability.

Define database models with clear naming, appropriate data types, constraints, relationships, and validation at multiple layers. Use this skill when creating or modifying database model files, ORM classes, schema definitions, or data model relationships. Apply when working with model files (e.g., models.py, models/, ActiveRecord classes, Prisma schema, Sequelize models), defining table structures, setting up foreign keys and relationships, configuring cascade behaviors, implementing model validations, adding timestamps, or working with database constraints (NOT NULL, UNIQUE, foreign keys). Use for any task involving data integrity enforcement, relationship definitions, or model-level data validation.

Use when designing or architecting Elixir/Phoenix applications, creating comprehensive project documentation, planning OTP supervision trees, defining domain models with Ash Framework, structuring multi-app projects with path-based dependencies, or preparing handoff documentation for Director/Implementor AI collaboration
