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 you need to add a new element shape to the LikeC4 codebase. Trigger this skill whenever the user mentions adding a shape, creating a new shape, implementing a shape, or asks about how shapes work in LikeC4. Also trigger when the user provides a visual reference image and wants it turned into an element shape. Even if the user just says "new shape" or drops an image of a shape they want — use this skill.
Generates changeset files based on changes. Use when user asks to create a changeset or at the end of a feature implementation, when the user asks to wrap up or finalize changes
