Empty Architecture (Archi Vide)

Generate code scaffolding that is:

• Empty: no business logic, no side effects.
• Predictable: explicit dependencies and module boundaries.
• Readable: relationships are clear from type signatures + minimal doc comments.
• Strictly typed: type composition + generics by default.

Trigger this skill whenever the user asks for:

• A project/module skeleton, scaffolding, or “architecture”
• Stubbed code, interfaces, ports/adapters, clean architecture, DDD boundaries
• “Empty implementation” files to be filled later

Output contract

Always deliver:

1. File tree (final structure).
2. Code for each file (or only the files the user requests).
3. One short rationale explaining boundaries + dependency direction.
4. An architecture note: an archi-*.md document (global → details) including: why, external impacts, expected results.

Non-goals

• No real behavior, no algorithm, no persistence, no network calls.
• No heavy abstraction, no frameworks unless the user explicitly asks for one.
• No speculative features.

Required loading (selective)

Always apply:

• Naming (mandatory): Use Skill naming-convention for every single identifier (files, folders, modules, namespaces, classes, types, interfaces, functions, methods, parameters, return types, variables, properties, DB tables/columns, routes).
  • Fallback if naming-convention is unavailable: camelCase functions/variables, PascalCase types/classes/components, kebab-case JS/TS/CSS files, snake_case Python/Ruby/Dart/Go files, SCREAMING_SNAKE_CASE constants — and keep names prefix + entity (+ suffix) shaped.
• Types: load references/type-rules.md.
• Stubs: load references/stubs.md.
• Architecture note: load references/architecture-doc.md.

Default folder layout (omit folders you don’t need):

• domain/, application/, ports/, infra/, api/

Load exactly one language profile:

• TypeScript: languages/typescript.md
• Python: languages/python.md
• Ruby: languages/ruby.md
• Dart/Flutter: languages/dart-flutter.md
• Go: languages/go.md

Load patterns only when needed:

• IO boundaries: patterns/ports-and-adapters.md
• Persistence: patterns/repository.md
• Use-case coordination: patterns/service.md
• DTO translation: patterns/adapter.md
• Complex construction: patterns/factory.md

Generation procedure

1. Ask for the target language/runtime if unknown (TypeScript/Node, Python, Go, etc.).
2. Ask for the primary module boundary (feature name) and the IO needs (DB? HTTP? queue?). 2b. If codebase-memory-mcp is available and this scaffold lands inside an existing repo, check index_status first — index it (index_repository) if it isn't yet, then call get_architecture(aspects). The new module's folder layout and dependency direction must match the codebase's actual boundaries, not just the default layout below. No MCP, greenfield repo, or not worth indexing for a single scaffold → use the default layout as-is.

MCP names are bare, not callable as written. Prefix cbm_ under pi, mcp__codebase-memory-mcp__ under Claude Code. Under pi, trace_path, query_graph, detect_changes, get_architecture and get_graph_schema need one cbm_search_tools call first. 3. Load only the files required by the context (language + patterns). 4. Produce a file tree including archi-<feature>.md. 5. Generate strictly-typed stubs that compile and remain obviously empty.
