Use when working with `.c4`/`.likec4` files or LikeC4 CLI/config questions where exact DSL/CLI syntax is required, especially for strict command/snippet-first answers, validate/export flags, predicates `*`/`_`/`**`, deployment snippets, dynamic views, or relationship extension matching.
Use when planning, reviewing, or correcting a LikeC4 model and you need to decide the right top-down design order (C1→C2→C3), whether C3 detail is warranted, or when to hand off from structural modeling to deployment or dynamic-view skills.
Use when editing `likec4.config.json`, include paths, image aliases, or splitting one project into a small set of focused LikeC4 files without redesigning the whole workspace.
Use when creating or modifying LikeC4 elements (systems, containers, components, nodes) with proper naming conventions, required metadata, and correct C4 hierarchy placement.
Use when connecting LikeC4 elements and you need to choose the exact logical or deployment relationship kind, place technology in the right field, or decide whether a connection belongs in the model or only in deployment.
Use when documenting a LikeC4 use case, temporal flow, or async behavior as a dynamic view, especially when order matters more than structure.
Use when adjusting an existing LikeC4 view with styling, layout hints, drill-down navigation, or external links, without changing the structural contents of the view.
Use when creating or updating architecture views with proper element inclusion, parent context, neighbor relationships, and category folder organization (C1/C2/C3/Use Cases/Deployment/Operations).
