Design guidance for creating interfaces and visual assets for AUV, a tool for replaying and inspecting command runs. It defines AUV’s product context, language style, colors, fonts, icons, and interface components.

Use it when designing AUV production interfaces, prototypes, terminal views, inspection viewers, status indicators, or branded visual assets.

It keeps AUV-related screens and assets visually consistent with the project’s forensic, status-focused style. It also distinguishes documented states such as validated, candidate, running, and failed without inventing new statuses.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.00628
Opus 5	$0.00030	$0.00314
Sonnet 5	$0.00012	$0.00126
Haiku 4.5	$0.00006	$0.00063

Security

Grade A, and why

auv-design 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 7d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AUV Design

Read README.md in this skill first — it establishes product context, content fundamentals (the deliberately anti-marketing AUV voice), visual foundations, and iconography rules.

Then explore the other files:

colors_and_type.css — all design tokens (--auv-*).
assets/ — logo mark + wordmark.
preview/ — small reference cards for each system concept.
ui_kits/cli/ — auv-cli terminal output recreation.
ui_kits/viewer/ — speculative inspect-viewer mock (the browser viewer described in 2026-05-19-trace-run-inspect-design.md; not built yet in the source repo).

Operating principles for this brand

Honesty over polish. AUV documents what is validated, candidate, and not-validated in JSON. Reflect that in every artifact. Never invent a status not on the canonical list.
Monospace carries identity. IDs, paths, span names, and JSON keys live in JetBrains Mono. Body prose lives in Geist.
No emoji. No gradients. No glassy overlays. This is forensic-grade UI.
Status pill is the smallest unit. Use .auv-status--{validated, candidate, boundary, frozen, running, failed} everywhere a status is shown — sidebars, lists, headers, terminal output, marketing.

When the user invokes this skill

If creating visual artifacts (slides, mocks, throwaway prototypes), copy assets out of this skill and produce static HTML the user can view. Reuse the <Terminal> / <SpanTree> / <Sidebar> components from the UI kits when the output is product-facing.

If working on production code (Rust CLI, future browser viewer, future docs site), copy colors_and_type.css and assets/logo-*.svg into the project, and follow the rules in README.md (sections Content Fundamentals and Visual Foundations) to extend the system.

If invoked without other guidance, ask the user what they want to build — typical asks are:

a mock of auv-cli output for a docs page or social post
a wireframe / mock of the inspect viewer
a slide deck explaining a phase-1 boundary
copy in the AUV voice (status report, freeze note, boundary callout)

Changes

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.

auv-design is a skill published in the GitHub repository moeru-ai/auv (25 stars, last pushed 3d ago), licensed Apache-2.0. It adds 60 tokens to every session and 628 once invoked, about $0.0003 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.
