A skill for reviewing a named user-interface scenario or preparing one limited improvement packet for execution.

Use it to review or improve a known frontend interaction with the required visual evidence and review process.

It keeps UI review tied to a registered scenario and separates visual checking from actually applying fixes.

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	$0.00014	$0.00267
Opus 5	$0.00007	$0.00133
Sonnet 5	$0.00003	$0.00053
Haiku 4.5	$0.00001	$0.00027

Security

Grade A, and why

ui 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (visual-report-bundle/scripts/capture-visual-report.cjs), 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.

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.

What it actually says

UI

Read docs/procedures/visual-review.md before acting; it owns commands, hard-gate authority, critic bounds, packet rules, providers, and owner handoff. Also follow docs/procedures/MODEL-CARD.md. When the registered review needs a screenshot/video/HTML proof bundle or an iterative evidence handoff, read and follow visual-report-bundle.md; it is an internal reference of this skill, not a separately invocable skill.

Accept only explicit review <registered-spec> or improve <registered-spec>. Resolve the exact name through the repository registry; reject URLs, paths, configs, commands, and unknown names.

review is read-only and reusable by reviewer agents for changed frontend components or behavior; it leaves a bounded spec-defined report.
improve creates one checkout-bound execution packet; validate it, then invoke /skill:exec <run>/execution-packet.json exactly once.

Never apply packet fixes here, recurse into improve, auto-run provider hooks, or treat advisory critic scores as hard gates.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

ui is a skill published in the GitHub repository hachej/boring-ui (46 stars, last pushed today), licensed MIT. It adds 14 tokens to every session and 267 once invoked, about $0.0001 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 2026-09-03.
