ss-verify

ss-verify is a skill for Claude Code, Codex from bitjaru/styleseed. It costs 40 tokens per session (2,007 once invoked), scanned A, original, MIT.

A visual checking process for UI code or another visual artifact: render the result, inspect the actual pixels, and fix problems against the project's StyleSeed rules. Rendering means producing the screen or image as users will actually see it.

In plain words
What is it for?
Use it to verify a page, component, or visual artifact after implementation. It checks the rendered appearance against the resolved artifact rules and repeats the render-and-fix cycle until the result passes.
Why use it?
Code can look correct while the rendered result still has unreadable text, empty space, cramped cards, failed fonts, or weak visual hierarchy. Looking at the output catches problems that source-code review cannot.

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

ss-verify 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 4d 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.

Verify (look at it, don't just read it)

Registry-first artifact boundary

When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact ID first, then read only .styleseed/bundles/<artifact-id>.md and .styleseed/manifests/<artifact-id>.json. Never fall back to the global legacy bundle for a registry project. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.

Read .styleseed/effective-rules.md and .styleseed/manifest.json; invoke /ss-resolve or $ss-resolve first when they are missing or stale. Judge pixels against that compiled method. A lock value cannot excuse a core failure, and a recipe/profile cannot replace the output grammar.

/ss-score reads the code and scores it. But some of the worst "AI-made" tells never appear in source — they only exist in pixels: a hero that doesn't actually dominate, a lower third of dead whitespace, cramped cards, a web font that silently failed to load and fell back to Times, two colors that look like two accents once rendered, text that's unreadable on its real background. A human sees these in half a second; a code-reading gate misses all of them.

/ss-verify closes that gap: it renders the UI, screenshots it, and you look at the image — then score the same StyleSeed gate against what you see, fix, and re-render. This is the gate that most predicts whether a real user will say "this looks designed."

Run it as the final gate after /ss-score passes — code-clean is necessary but not sufficient; pixel-clean is the real bar.

When NOT to use

  • Nothing renderable yet (pure logic/config, or a component with no host page) → use /ss-score.
  • No way to render at all (no browser, no Playwright, headless blocked) → say so, fall back to /ss-score, and tell the user the visual gate was skipped. Never claim you verified visually if you didn't actually see a screenshot.
  • A quick pre-commit pass → /ss-lint. /ss-verify is heavier (it boots a renderer).

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.

ss-verify is a skill published in the GitHub repository bitjaru/styleseed (939 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 2,007 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
