A tool for creating product screenshots and screenshot-based hero images and README sections for GitHub repositories. It helps show a software product through real interface images.

In plain words
What is it for?
Use it to add software screenshots, create a README hero image, make localized interface captures, or build a screenshot collage for a GitHub project.
Why use it?
It removes the work of explaining a graphical product with text alone. It also helps keep visual README content aligned with the product and its languages or regions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

github-readme-visuals scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub README Visuals

Create a fast, trustworthy visual explanation of the product without replacing its factual README content.

Workflow

  1. Inspect the repository before designing.

    • Read the README, product notes, local instructions, existing assets, and available screenshots.
    • For application repositories, prioritize real product screenshots as proof. Do not present generated UI as a real screen.
    • Identify the user journey a first-time visitor should understand in one glance.
    • Build a visual-claim ledger before writing hero copy: every product, pricing, privacy, credential, provider, and deployment claim must be supported by the README, source, or user-confirmed facts. Omit ambiguous claims instead of guessing.
  2. Establish visual direction.

    • When Creative Production is available, use its style intake before generating a new direction. Use moodboard-explorer when the user asks for multiple visual territories or concept options.
    • If the user does not choose a direction, use a restrained default: one original hero, product-led composition, readable hierarchy, and a palette derived from the repository's existing UI or brand assets.
    • Directly inspect every supplied reference before production. Record its canvas ratio, major spatial split, dominant visual, screenshot count, overlap, rotation, off-canvas clipping, shadows, typography blocks, and decorative motifs.
    • When the user explicitly requests a layout or style match, preserve the reference's composition grammar and visual hierarchy while replacing its UI, logo, copy, branding, and assets with material from the target repository.
    • Measure repeated screenshot frames instead of estimating them independently. If the reference uses equal-size frames, define one canonical width and aspect ratio for every screenshot; create hierarchy through position, overlap, off-canvas clipping, rotation, contrast, and z-order rather than arbitrary scaling.
    • When the brief says one-to-one, exact, or fully replicated, create a pixel geometry table before editing. Record canvas size; each screenshot's four corners, frame width and height, rotation, off-canvas clipping, and z-order; distances between adjacent frames; and each decorative shape's orientation and anchor point.
    • Derive CSS positions from measured corners and rotation. Do not substitute a visually similar arrangement or independently eyeball each frame.
    • Do not start final production from a moodboard or verbal summary alone when an exact reference image is available.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
