Turns the pipeline's design documents into a running system. Reads the architecture document and implementation plan, executes each ecosystem's current official project generator to create the real repo structure (one deployable unit per architecture container, monorepo by default), wires the walking skeleton end-to-end — UI shell with the design system's tokens.json, API, domain stub, local database — stands up the engineering foundations (CI, environments, test harness, deployment config written but not executed), and verifies empirically by building and running the skeleton test. Deploy-ready, not deployed. Use after implementation-planning and before per-slice work, when the plan's walking skeleton needs to become a real repo. Trigger on "scaffold the project", "set up the repo", "create the project structure", "build the walking skeleton", "initialize the codebase", or "stand up the skeleton". Checkpoints progress and resumes safely — never regenerates over a partial scaffold.

Establishes the UX and design foundations for an application before feature work begins — the "architecture of the UI." Consumes the upstream SRS (docs/srs.md) and architecture document (docs/architecture.md) when present, then builds the design system from one of four user-chosen source modes: research a new direction, extract from reference images, ingest an existing design file, or pull from a connected design tool (e.g., Figma via MCP). Produces docs/ux-foundations.md (personas, IA, navigation, flows, screen inventory per surface), docs/design.md (agent-ready design system: tokens, components, states, layout and usage rules), and tokens.json (W3C DTCG). Use in the design phase, after architecture and before implementation planning, for any application with one or more UI surfaces. Trigger on "design the UX foundations", "set up the design system", "what should the UI look like", "plan the screens and navigation", or "create the design language".

Designs the software architecture for a new application, service, or major feature through a structured interview, then produces an architecture document (arc42-style, with C4 diagrams in Mermaid and Architecture Decision Records). Use this whenever the user is starting a greenfield system or a significant new feature and would benefit from thinking through structure, quality attributes, tech stack, and trade-offs before writing code. Trigger on phrases like "design the architecture for", "I'm building a new app", "help me architect", "set up a new project/service", "what should the architecture be", "create an architecture doc/diagram", or any greenfield system-design discussion — even when the user does not say the word "architecture" explicitly but is clearly about to start building something new. If an SRS (docs/srs.md) exists, it designs from those requirements and NFRs, interviewing only for gaps. Prefer this skill over answering from memory whenever real architectural trade-offs are in play.

Runs the requirements-engineering phase — the first SDLC step, upstream of design. Through a thorough, area-by-area interview it elicits and specifies the complete requirements for a new application, proactively enumerating the standard sub-requirements for each capability area (for authentication: sign-up, sign-in, verification, password reset, logout) plus all non-functional requirements. Produces a structured SRS (ISO/IEC/IEEE 29148 lineage) in markdown, a separate use-case document in markdown, and a requirements traceability matrix. Also amends a finalized SRS — adding, updating, or removing requirements with stable IDs. Use at the start of a project before architecture and UX, or when changing existing requirements. Trigger on "gather requirements", "write an SRS", "requirements engineering", "specify the requirements", "add a requirement", or "update the requirements". Saves progress incrementally so long sessions can resume.
