Create and manage database migrations with reversible changes, zero-downtime deployments, and proper version control practices. Use this skill when creating database migration files, schema change scripts, or any files that modify database structure. Use this when writing migration files with up/down methods, implementing rollback strategies, creating or modifying database tables, adding or removing columns, creating indexes, or handling data migrations separately from schema changes. Use this when working on files in migration directories like db/migrate/, migrations/, or database/migrations/, or when modifying schema definition files.

Autonomously execute exploratory implementation of one approach from spike definition, working independently until natural stop. Use when partner provides spike definition and assigns you an approach number to explore in isolation, when comparing multiple implementation alternatives, or when evaluating technical feasibility before committing to an approach

Standards enforced when writing code, creating pull requests, committing changes, or documenting features. CRITICAL - No emoji in developer-facing content (code/docs/PRs/issues/commits) or CLI output. Also defines standards for using cutting-edge language features and writing comprehensive documentation. Should be applied to all development work.

Phase 4 of Ontology Builder Pipeline. Generates final Ontology artifacts (entity definitions, workflow catalog, concept guides) from DRD. Use after Phase 3 DRD is complete.

Define and structure database models with clear naming conventions, timestamps, data integrity constraints, appropriate data types, and relationship definitions. Use this skill when creating or modifying database model files in directories like models/, entities/, schemas/, src/models/, app/models/, or any ORM model definition folders. Use this when defining model classes with ORMs like Sequelize, TypeORM, Prisma schema, Django ORM models, Rails ActiveRecord models, SQLAlchemy models, Mongoose schemas, or any database ORM framework, adding or modifying database constraints like NOT NULL, UNIQUE, CHECK constraints, or foreign key relationships to enforce data integrity at the database level, defining model relationships such as hasMany, belongsTo, hasOne, belongsToMany, ManyToMany, or OneToMany associations between entities to represent how data is connected, implementing validation rules at the model layer for data integrity including required fields, format validation, and custom business rule validation, ch

This skill should be used when the user asks about "prompt_toolkit key bindings", "KeyBindings", "keyboard shortcuts", "key handler", "key sequences", "c-x c-c", "ConditionalKeyBindings", "filters for keys", "vi mode bindings", "emacs bindings", or needs to define keyboard interactions in prompt_toolkit applications.

Define custom workflows with steps, triggers, and conditions as markdown files

Define and use theme variables with @theme directive, oklch() color format, semantic naming, and namespaced utilities. Use when customizing design tokens or creating design systems.

Defines the standard 8-category taxonomy for classifying project files: Config, Tests, Docs, Scripts, Source Code, Data, AI Tooling, and Other. REFERENCE THIS SKILL whenever categorizing files, auditing project structure, or answering 'what types of files are here.' Apply these categories and patterns whether using the bundled script or manual analysis.

Standard agent pipelines for audit, coding, new project, refactor, and simple workflows. Defines 5 workflow types with specific agent sequences (AUDIT: BA→PM→Workers→Reviewer→PM, CODING: Architect→PM→Workers→Validator→Reviewer→PM, NEW_PROJECT and REFACTOR follow coding pipeline, SIMPLE: direct processing). Includes agent contracts, workflow detection logic, and orchestration best practices. Use when /ms command needs to determine workflow type and coordinate multi-agent execution.

Use when converting an existing Python project into an MCP server via the web editor: create an mcp_{server} folder, build a facade service.py with @mcp_service, auto-pick key functions to expose, seed tool_definition_templates.py with defaults, and wire editor_config.json so the tool editor can generate tool_definitions.py/server.py.

Generates production-ready BAML applications from natural language requirements. Creates complete type definitions, functions, clients, tests, and framework integrations for data extraction, classification, RAG, and agent workflows. Queries official BoundaryML repositories via MCP for real-time patterns. Supports multimodal inputs (images, audio), 6 programming languages (Python, TypeScript, Ruby, Java, Go, C#), 10+ frameworks, 50-70% token optimization, and 95%+ compilation success.

A2A agent card JSON templates with schema validation and examples for different agent types. Use when creating agent cards, implementing A2A protocol discovery, setting up agent metadata, configuring authentication schemes, defining agent capabilities, or when user mentions agent card, agent discovery, A2A metadata, service endpoint configuration, or agent authentication setup.

ENFORCEMENT tool that detects when Skills automation is duplicated in agent definitions, lessons learned, or process docs. Prevents "single source of truth nightmare" by finding bash commands, step-by-step procedures, or process descriptions that replicate Skills. BLOCKING AUTHORITY - workflow cannot complete with violations.

Plan, structure, and scaffold large educational books using cognitive load management,just-in-time specification, and pedagogical best practices. Use this skill when planningmulti-part, multi-chapter educational works that require narrative continuity, progressivecomplexity, and hands-on exercises. This skill helps create cohesive learning journeysthat balance foundational scaffolding with advanced independence. Activate when tasksinvolve structuring books, managing cognitive load across chapters, defining part-levelnarratives, or coordinating multi-phase content development workflows.

Guide users through structured feature specification creation from idea to complete spec. Use when user wants to create a feature specification, product requirements document (PRD), technical spec for a feature, or similar structured feature planning documentation. This workflow helps users efficiently gather context, explore the codebase, define requirements, draft technical approach, and save the result to JIRA or Confluence. Trigger when user mentions "create a spec", "spec out", "write a PRD", "feature specification", or similar feature planning tasks.

Complete task lifecycle management system with state-based workflow. Define, refine, implement, and review tasks with automated quality gates and intelligent discovery.

Business strategy expert - defines users, value propositions, use cases, and business requirements. Connects technical development with market realities and ROI. Includes LATAM market (Chile) specialization.

Guide for creating Claude Code hooks - user-defined shell commands that execute at lifecycle points. Use when the user wants to create, add, or configure a hook for Claude Code, including PreToolUse, PostToolUse, Notification, UserPromptSubmit, Stop, SubagentStop, PreCompact, SessionStart, or SessionEnd hooks.

TheGraph subgraph development with AssemblyScript handlers, schema definitions, and Matchstick testing. Triggers on subgraph, thegraph, graphql, mapping.ts.
