build_asset_from_spec
Builds a sprite from a specification by creating scaffolding, applying palette, layers, animations, and running exports without drawing pixels.
Instructions
Build the asset described by an aseprite_mcp.asset_spec.v1 document.
Executes the (validated) plan by dispatching each step to an existing tool: scaffolds
the sprite for its `kind`, applies palette / extra layers / animation frames+tags /
slices, and runs the requested exports. **Structure only — no pixels are drawn;** the
returned manifest's `suggested_next_actions` hand the actual art back to you.
Args:
overwrite: Passed to the export steps (replace existing export files). The sprite
itself is created no-clobber, so building over an existing ``<name>.aseprite``
raises — build to a new name or remove the old file.
Returns a ``workflow_manifest.v1`` (kind ``asset_spec``) with the created files, the
executed `plan`, and next actions. Raises ``ValidationFailed`` if the spec is invalid.
