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.

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 | $0.00050 | $0.00917 |
| Opus 5 | $0.00025 | $0.00458 |
| Sonnet 5 | $0.00010 | $0.00183 |
| Haiku 4.5 | $0.00005 | $0.00092 |
Grade A, and why
ux-baseline-check 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 12d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UX Baseline Check
Core Pack — Always Active
This is a core skill. Apply it on ALL visual and frontend work alongside design-review.
Every screen ships with ALL states covered. No exceptions. This is the minimum bar.
The State Inventory
Before any page or component is "done", verify each applicable state exists:
1. Data States
- Empty — no data yet. Helpful message + clear CTA, not a blank screen
- Loading — skeleton, spinner, or shimmer. Never a white flash
- Loaded — the happy path, obviously
- Error — API failure, network issue. User-friendly message + retry action
- Partial — some data loaded, some failed. Don't hide what works
- Long content — what happens with 200 items? 2000-character names? Test it
2. Interaction States
- Hover — every clickable element has a hover state
- Focus — keyboard navigation works, focus rings visible
- Active/pressed — buttons respond to clicks visually
- Disabled — grayed out with clear reason why (tooltip or helper text)
- Selected — multi-select, current tab, active filter all visually distinct
- Adjacent-action consistency — when a state is read-only, disabled, offline,
permission-limited, or destructive, inspect every nearby primary, secondary, toolbar, and inline
action. Remove, relabel, or visibly explain contradictions; use native
disabledsemantics when an inactive control remains visible, and preserve active actions in unaffected states.
3. Form States
- Validation — inline errors on blur, not just on submit
- Required fields — clearly marked
- Success feedback — user knows their action worked (toast, inline, redirect)
- Destructive confirmation — delete/remove actions require confirmation
- Autofill — doesn't break layout when browser autofills
4. Responsive
- Mobile (375px) — usable, not just visible. Touch targets ≥48px with ≥8px spacing between them
- Tablet (768px) — layout adapts, not just shrinks
- Desktop (1280px) — the primary target, looks intentional
- Wide (1800px+) — content doesn't stretch absurdly. Max-width or centered
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.

ux-baseline-check is a skill published in the GitHub repository aa-on-ai/agentic-design-system (5 stars, last pushed 22d ago), licensed MIT. It adds 50 tokens to every session and 917 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 2026-08-31.
