postcard-illustration skillA

postcard-illustration is agent-read markdown (skill) from vm0-ai/vm0-skills: Hand-drawn editorial postcard illustration style. Fine black marker/pen ink linework over flat saturated gouache color fills with sharp edges, dense small repeated ink patterns on surfaces (rows of windows, shingle curves, hatching, stippling), subtle paper-grain background texture, tiny scattered white speckles (snow / petals / sparkle), and a tall portrait composition with a layered foreground-midground-background. Travel-journal / urban-sketcher aesthetic. Trigger when the user says /postcard.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
