shipstats is a Claude Code marketplace skill that converts weekly metrics JSON and a design-system markdown spec into a self-contained 1080×1200 screenshot-ready HTML poster for developers posting brand-aligned shipping
About
shipstats is a prompt-as-a-tool packaged as a Claude Code marketplace plugin for founders and developers who ship weekly and post progress without rebuilding Figma layouts each time. Drop metrics JSON, design-system tokens, and an optional logo into PROMPT.md or invoke the bundled skill; the agent returns a single self-contained HTML file at 1080×1200 with Google Fonts, base64-embedded logo, and a fixed section structure—header, optional growth timeline, hero metric, breakdown, daily peak. The skill renders only numbers present in input data with zero invented metrics. A bundled Python script resizes logos to 128×128 WebP plus base64. Install via /plugin marketplace add mativallej/shipstats or paste PROMPT.md into any long-context LLM. Developers reach for shipstats when Sunday recap posts need the same series look with updated numbers, not a one-hour design session.

FAQ
What canvas size does Shipstats produce?
Shipstats produces a single self-contained HTML file on a 1080×1200 canvas that auto-scales to the viewport while preserving aspect ratio. Fonts load via Google Fonts with preconnect and logos embed as base64 data URIs so the file needs no external assets.
What inputs does Shipstats require?
Shipstats needs metrics as JSON or prose, a design-system markdown spec with palette, fonts, gradients, and spacing tokens, and an optional PNG or JPG logo attachment. Missing design tokens fall back to templates/design-system.md defaults shipped with the skill.
Does Shipstats invent metrics if data is sparse?
No—Shipstats follows a zero-invention rule and renders only numbers present in the supplied data. Sections omit cleanly when metrics are missing, with no placeholder filler or hallucinated growth figures.
