Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to low
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- low Excessive Agency · line 100 Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.
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 | $0.00112 | $0.01644 |
| Opus 5 | $0.00056 | $0.00822 |
| Sonnet 5 | $0.00022 | $0.00329 |
| Haiku 4.5 | $0.00011 | $0.00164 |
Grade A, and why
ui-quality-loop 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

UI Quality Loop
Overview
Run a tight quality loop until the UI clears gates (or hit the iteration cap). This is the pack’s mini lifecycle — not full /spec→/ship, but build → prove → audit → fix until it’s good.
JUDGE* → BUILD → TEST → AUDIT ──Critical/High──▶ FIX ──▶ TEST → AUDIT …
│
PASS → DONE
* Judgment only on blank-canvas / first pass (see frontend-judgment skip rules).
When to use
- User asks to polish, rapihin, “sampai lulus audit”, “UI bagus dulu baru selesai”
/polishor natural language equivalent- After a
/design//auditwith Critical/High findings and user wants them cleared
When to skip
- Single-line copy/token tweak with no quality ask
- Pure audit with no fix permission (“audit saja”)
- User said stop / “cukup” / accepted remaining Medium/Low
Agents (orchestrate — do not nest personas forever)
| Step | Agent |
|---|---|
| Judgment + build + fix | ui-developer |
| Test | test-engineer |
| Audit | design-reviewer |
You (the session agent) are the loop controller. Personas do not call each other; you invoke their workflows in sequence.
Gates (pass / fail)
| Gate | Pass when |
|---|---|
| Anti-slop | No Critical/High AI-aesthetic findings |
| UI feel | No Critical/High craft issues on touched UI (concentric radius, hit overlap, transition: all, broken press/enter) |
| Tokens | No Critical/High raw-hex / off-token issues; greenfield pack preset used decision tree + Token score / (explicit) / (hard-gate) / project system in Conventions check |
| Responsive | Conventions Responsive line present; full-width primary CTA <768; no Critical/High desktop-only layout on greenfield (320–1440) |
| Hierarchy | Hierarchy pass (one primary focus + one primary CTA) or waiver for tiny tweaks |
| Typography | One h1/page + sequential ladder (or waiver) |
| Motion | Shell light defaults or named families/patterns from motion-families.md; no decorative spam; reduced-motion; hand-roll (not registry default) |
| Shell | Theme in topbar; avatar → account menu; custom selects (or waivers) on dashboards |
| Landing | Marketing section stack via marketing-landing (not hero-only; hand-roll) — or n/a for app-shell-only |
| A11y | No Critical keyboard/label/contrast findings (potential or measured) |
| States | Loading/error/empty handled for interactive surfaces touched |
| Tests | Planned critical cases green, or explicit waiver if no test runner / out of scope (document why) |
| Perf (soft) | No Critical obvious LCP/CLS footguns in touched UI; else note as remaining |
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-quality-loop is a skill published in the GitHub repository sukirman1901/frontend-expert (10 stars, last pushed 4d ago), licensed MIT. It adds 112 tokens to every session and 1,644 once invoked, about $0.0006 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 2026-08-31.
