reflect
kriegcloudSelf-improving AI memory system that persists learnings across sessions in skill-specific MEMORY.md files. Use when capturing corrections, remembering user preferences, or extracting patterns from successful implementations. Enables continual learning without starting from zero each conversation.
react-composition
kriegcloudBuild composable React components using Effect Atom for state management. Use this skill when implementing React UIs that avoid boolean props, embrace component composition, and integrate with Effect's reactive state system.
ai-context-writer
kriegcloudCreate and update ai-context.md files that document modules for AI assistants. Use when adding documentation for packages, apps, or external references that should be discoverable via /modules commands.

legal-review
kriegcloudOrchestrate lawyer agents to review code for compliance with codebase laws. Spawns counsel in parallel to produce a unified legal brief.
context-witness
kriegcloudDecide between Context Tag witness and capability patterns for dependency injection, understanding coupling trade-offs
effect-ai-language-model
kriegcloudMaster the Effect AI LanguageModel service for text generation, structured output, streaming, and tool calling. Use when working with LLM interactions, schema-validated responses, or building conversational AI systems.
error-handling
kriegcloudImplement typed error handling in Effect using Data.TaggedError, catchTag/catchTags, and recovery patterns. Use this skill when working with Effect error channels, handling expected failures, or designing error recovery strategies.
react-vm
kriegcloudImplement the VM pattern using Effect and Effect-Atom for reactive, testable frontend state management. Use this skill when building React applications with View Models that bridge domain services and UI.
domain-modeling
kriegcloudCreate production-ready Effect domain models using Schema.TaggedStruct for ADTs, Schema.Data for automatic equality, with comprehensive predicates, orders, guards, and match functions. Use when modeling domain entities, value objects, or any discriminated union types.
the-vm-standard
kriegcloudThe VM Standard - inviolable covenants governing View Model architecture in this codebase. These covenants SHALL NOT be violated under any circumstance.
parallel-explore
kriegcloudParallel exploration of codebase questions by decomposing into independent tracks. Use when exploring architecture, understanding systems, or investigating complex questions that benefit from multiple perspectives.
layer-design
kriegcloudDesign and compose Effect layers for clean dependency management
effect-ai-prompt
kriegcloudBuild prompts for Effect AI using messages, parts, and composition operators. Covers the complete Prompt API for constructing, merging, and manipulating conversations with language models.
effect-ai-tool
kriegcloudDefine and implement AI tools using @effect/ai's Tool and Toolkit APIs. Use when building LLM integrations with type-safe tool definitions, parameter validation, and handler implementations. Covers user-defined tools, provider-defined tools, and toolkit composition.
Better Auth Best Practices
kriegcloudA skill to integrate better-auth. And auth framework for TypeScript projects.
pattern-matching
kriegcloudMaster Effect pattern matching using Data.TaggedEnum, $match, $is, Match.typeTags, and Effect.match. Avoid manual _tag checks and Effect.either patterns. Use this skill when working with discriminated unions, ADTs, or conditional logic based on tagged types.
command-executor
kriegcloudExecute system commands and manage processes using Effect's Command module from @effect/platform. Use this skill when spawning child processes, running shell commands, capturing command output, or managing long-running processes with cleanup.
typeclass-design
kriegcloudImplement typeclasses with curried signatures and dual APIs for both data-first and data-last usage
wide-events
kriegcloudConceptual guide to wide events (canonical log lines) for observability. Use when thinking about instrumentation strategy, span annotations, or designing what context to capture.
schema-composition
kriegcloudMaster Effect Schema composition patterns including Schema.compose vs Schema.pipe, transformations, filters, and validation. Use this skill when working with complex schema compositions, multi-step transformations, or when you need to validate and transform data through multiple stages.
Create Auth Skill
kriegcloudA skill to create auth service for new applications.
spec-driven-development
kriegcloudImplement the complete spec-driven development workflow from instructions through requirements, design, and implementation planning. Use this skill when starting new features or major refactorings that benefit from structured planning before coding.
platform-abstraction
kriegcloudUse @effect/platform abstractions for cross-platform file I/O, process spawning, HTTP clients, and terminal operations. Apply this skill when writing code that interacts with the filesystem, spawns processes, makes HTTP requests, or performs console I/O to ensure portability across Node.js, Bun, and browser environments.
