repo-visuals

repo-visuals is a skill for Claude Code from livlign/claude-skills. It costs 112 tokens per session (14,143 once invoked), scanned A, original, MIT.

A workflow for creating a hero visual—a prominent image or animation—for a GitHub repository’s README. It scans the repository, agrees on a creative brief, builds the visual, previews it, and exports an animated GIF, PNG, or animated SVG.

In plain words
What is it for?
Use it to create README visuals from a GitHub URL, local folder, or written brief. It supports discovery, scenario selection, HTML/CSS/JS or SVG design, browser previews, and export.
Why use it?
It helps explain what a repository does at a glance through a purpose-built visual. The workflow checks the proposed design against the repository and README before exporting it.

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

repo-visuals scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/capture.js, scripts/evaluate.js, scripts/screenshot.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 580 lines — stays where its author put it; the contents beside it link to each section on GitHub.

repo-visuals

Turn a repo (GitHub URL, local folder, or free-text brief) into a hero visual that a viewer sees at the top of the README and instantly understands what this project does and why it's interesting. The hero may be an animated GIF, a static PNG, or an animated SVG — the skill recommends one based on the repo's identity, the user picks.

The skill's quality comes from the discovery dialog, not from templates. Every hero is bespoke.

Phases

  1. Discovery — pick operating mode (Auto / Semi-auto / Manual, §1.1a), scan the repo, summarize findings, recommend a format (animated vs static), ask about vibe/audience/hero moment, propose 2–3 scenarios, converge on a brief. Then Gate A — brief vs README (§1.8): narrow repo-context check on the brief before any pixels exist. The mode controls how many of these the user answers vs. Claude decides silently — it does not skip any of the craft checks.
  2. Build — write HTML/CSS/JS for the chosen scenario. For static, design one decisive frame; for animated, a loop. No storyboard step. Then Gate B — rendered HTML vs README (§2.6): sample keyframes from the HTML, check what's on screen against the repo's own positioning, allow 1 auto-iteration if it fails. Both gates are deliberately narrow — only repo-context fidelity, not aesthetics or craft.
  3. Preview & iterate — open the HTML in the user's default browser, iterate in text until the user says ship.
  4. Export — animated GIF → Puppeteer screencast + ffmpeg palette pipeline. Static PNG → Puppeteer page.screenshot (with deviceScaleFactor: 2 for retina crispness). Animated SVG → author the SVG directly (CSS @keyframes or SMIL <animate> inside the file); no rasterization step — the source is the artifact.
  5. Output — place the hero in the target repo; optionally open a PR that embeds it in the README.

Dev mode (author-only): Phase 6 — Evaluate exists but only runs in dev mode. Dev mode is for the skill's author iterating on the skill itself; it collects scorecard data and writes run logs under ./evaluations/ in the user's current working directory. Enable it only when the user explicitly says "dev mode" (or sets REPO_VISUALS_DEV=1). In every normal run — including Manual, Semi-auto, and Auto — the skill ends after Phase 5. Do not mention Phase 6 to end users.

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.
