Create well-defined task specifications from plans or user prompts. Use when user wants to define a task, create a work item, break down a plan into actionable work, or write a spec for implementation. Triggers on "create task", "define task", "write spec", "break this down", "make this actionable", or when moving from planning to execution.

Generate JSON schemas and OpenAPI specs using justfile tasks (just gen, just gen-*-schema). Use when user modifies dataset manifests, API definitions, adds/removes schema fields, or mentions code generation, schemas, OpenAPI specs. Outputs to docs/manifest-schemas/ and docs/openapi-specs/.

dbt project structure using medallion architecture (bronze/silver/gold layers). Use this skill when planning project organization, establishing folder structure, defining naming conventions, implementing layer-based configuration, or ensuring proper model dependencies and architectural patterns.

Measure quality effectively with actionable metrics. Use when establishing quality dashboards, defining KPIs, or evaluating test effectiveness.

Guide for developing CommonTools patterns (TypeScript modules that define reactive data transformations with UI). Use this skill when creating patterns, modifying existing patterns, linking patches (instantiated patterns), debugging pattern errors, or working with the pattern framework. Triggers include requests like "build a pattern", "fix this pattern error", "deploy this charm/patch", "link these charms", or questions about handlers, cells, and reactive patterns.

Creates concise technical specification documents through 3-4 phase process. Guides through architectural decisions, system contracts, and technical design without getting bogged down in implementation details. Use when user wants to create a technical specification, needs to define how the system will be implemented technically, or is documenting architecture, data contracts, API specifications, and system components. Follows established feature development process with concise (5-10 page) specs focused on WHAT and WHY, not HOW to code. Optionally creates design brief for features with UI/UX complexity.

Creates vision documents through structured 5-phase discovery process. Guides through problem discovery, solution exploration, user needs analysis, future & scope planning, and document generation. Use when user wants to create a vision document for a feature, needs to define strategic context and high-level goals, or is starting feature development and needs to establish the "why" and "what" before technical details. Follows established feature development process with lean, focused documents (100-150 lines max) that flow from general problems to specific scope.

Creates requirements documents through structured 3-phase discovery process. Guides through requirements discovery, practical scoping, and generates consolidated requirements document with clear, practical language. Use when user wants to create a requirements document, needs to define what the system must do and quality constraints, or is documenting business capabilities, user workflows, and system requirements. Follows established feature development process with single consolidated document covering user stories, business data, rules, quality attributes, and success criteria.

Reusable QA harness for testing LLM agents and personas. Defines test suites with must-ace tasks, refusal edge cases, scoring rubrics, and regression protocols. Use when validating agent behavior, testing prompts after changes, or establishing quality baselines.
