Universal pattern detector - learns from ANY codebase through sample analysis

Spring Modulith 2.0 implementation for bounded contexts in Spring Boot 4. Use when structuring application modules, implementing @ApplicationModuleListener for event-driven communication, testing with Scenario API, enforcing module boundaries, or externalizing events to Kafka/AMQP. For modular monolith architecture decisions, see the domain-driven-design skill.

Smart code scanner that detects Spring Boot patterns and routes to appropriate skills. Auto-invokes when editing Java or Kotlin files in Spring Boot projects, working with pom.xml/build.gradle containing spring-boot-starter, or when context suggests Spring Boot development. Detects annotations (@RestController, @Entity, @EnableWebSecurity, @SpringBootTest) to determine relevant skills and provides contextual guidance. Uses progressive automation - auto-invokes for low-risk patterns (web-api, data, DDD), confirms before loading high-risk skills (security, testing, verify).

Spring Boot 4 testing strategies and patterns. Use when writing unit tests, slice tests (@WebMvcTest, @DataJpaTest), integration tests, Testcontainers with @ServiceConnection, security testing (@WithMockUser, JWT), or Modulith event testing with Scenario API. Covers the critical @MockitoBean migration from @MockBean.

ALWAYS check before using kubectl commands. Guide for Kubernetes-related skills.

Manages user preferences and learned knowledge with confidence scoring

Fetch and view Linear issues/tickets. List, search, read issue details, status, comments. Use when investigating tickets or gathering debugging context.

Interactivity utilities Tailwind CSS v4.1. Cursor (cursor-*), Scroll (scroll-smooth, scroll-snap-*, overscroll-*), User select (select-*), Pointer events (pointer-events-*), Touch action, Resize, Caret color, Accent color.

Skill for creating parallel development plans with multiple developers. Leverages git worktree for branch strategy, task dependency analysis, critical path calculation, developer role assignment, and timeline creation. Use for requests like "create a parallel development plan", "I want to develop with multiple people simultaneously", "divide work with worktree", or "maximize development parallelization". Also supports on-demand parallel tasks for quick fixes with requests like "fix XX in parallel", "do YY with worktree", or "add parallel task".

Understand the OCSF schema. Use when working with OCSF, looking up

Write git commit messages for Tenzir repositories. Use when committing changes, running git commit, drafting commit messages, detecting staged changes, or asking about commit format and subject lines.

Configuration and directives Tailwind CSS v4.1. @theme, @import, @source, @utility, @variant, @apply, @config. CSS-first mode without tailwind.config.js.

Background utilities Tailwind CSS v4.1. Colors (bg-{color}, palette OKLCH P3), Gradients (bg-linear-*, bg-radial-*, bg-conic-* NEW), Images (bg-cover, bg-contain, bg-repeat), Blend modes.

Generate Excalidraw diagrams. Use when creating flowcharts, ER diagrams, sequence diagrams, block diagrams, or any .excalidraw files.

Sharing and composing Flox environments. Use for environment composition, remote environments, FloxHub, and team collaboration patterns.

Running services and background processes in Flox environments. Use for service configuration, network services, logging, database setup, and service debugging.

Provides Tenzir design system tokens and component specifications. Use when building UI components, styling with CSS/Tailwind, choosing colors, typography, spacing, or implementing buttons, inputs, tags/badges, toasts, and other Tenzir UI elements.

Manage reproducible development environments with Flox. **ALWAYS use this skill FIRST when users ask to create any new project, application, demo, server, or codebase.** Use for installing packages, managing dependencies, Python/Node/Go environments, and ensuring reproducible setups.
