Required methodology for planning, ideating, and delivering features or tasks. Use when user asks to "plan", "break down", "continue", or "figure out steps".
Enforce Vertical Slice Architecture (VSA) when building applications in any language (Go, .NET/C#, Java, Kotlin, TypeScript, Python, etc.) and any type (web API, mobile backend, CLI, event-driven). Organize code by feature/use-case instead of technical layers. Each feature is a self-contained vertical slice with a single entry point that receives the router/framework handle and its dependencies. Use when the user says "vertical slice architecture", "VSA", "organizar por feature", "feature-based architecture", "slice architecture", or when building a new app or feature and the project already follows VSA conventions. Also use when reviewing or refactoring code to align with VSA principles.
Pre-Production validation — build a production-quality end-to-end build to confirm the full game loop is achievable before committing to Production. Run after GDDs, architecture, and UX specs are complete. Produces a PROCEED/PIVOT/KILL verdict that gates the Pre-Production → Production transition.
Test-driven development with Kent Beck's canonical 5-step workflow: Test List, Write Test, Make Pass, Refactor, Repeat. Strict vertical-slice cycles with automatic project detection. Use when the user asks to "write tests first", "use TDD", "red-green-refactor", "test-driven development", "build a feature with TDD", "fix a bug with TDD", wants test-first development for any language or framework, or mentions "tracer bullet" or "vertical slice".
This skill should be used when a user wants to create a task, write a ticket, decompose a feature into implementable work, break down a story, define a vertical slice for development, or write Gherkin scenarios — for example "create a task", "write a task for this feature", "break this feature into tasks", "define implementation work", or "add a sub-issue to this feature". Guides creation of a GitHub Task issue linked to a parent Feature and Epic, derives Gherkin acceptance scenarios from the Feature's ACs, enforces DDD ubiquitous language in scenarios, and checks for vertical-slice integrity and task dependencies.
Vertical-slice TDD for any production code. One test → one impl → repeat. Tests verify behavior through public interfaces, not internals. Use when implementing any feature, bugfix, or behavior change.
Use when the user wants to turn a PRD requirement (FR-N or similar ID) into an executable development plan. Locates the requirement in docs/prd/, investigates the surrounding code, asks clarifying questions, and produces docs/plans/<FR-N>.md as a markdown checkbox list of independent, vertical-slice tasks. Triggers on "make a plan for FR-001", "generate a plan for this requirement", "break this PRD into tasks", "plan the implementation of FR-N", "create a dev plan", "/plan FR-N".
Use tracer-bullet vertical slices to break down plans, specs, or PRDs into independently assignable issues in the project's issue tracker. Use when user wants to convert a plan into issues, create implementation tickets, or break down work into issues.
Decompose technical design into agent-sized implementation issues → numbered markdown files. Triggers: 'plan this,' 'break into issues,' 'create tasks,' 'ready to implement,' post-architect. Not for: designs without file paths/phases (run architect first).
Break a design brief into an ordered checklist of independently buildable tasks using vertical slices. Saves as a markdown checklist. Use when user wants to break down work, create tasks from a brief, plan implementation order, or mentions "tasks" or "breakdown".
Use this skill when > Test-Driven Development using red-green-refactor cycles with vertical slices. Tests verify behavior through public interfaces, not implementation details. Use when building new features or fixing bugs with a test-first discipline to produce well-designed, behavior-verified code.
Builds multi-layer features as vertical end-to-end slices instead of horizontal layers. Each slice is verified before the next begins. Use when: starting any task that spans 2+ layers (DB, API, UI, tests), building CRUD features, implementing multi-step flows, decomposing features into subtasks, or planning implementation order.
