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 | $0.00105 | $0.02927 |
| Opus 5 | $0.00053 | $0.01463 |
| Sonnet 5 | $0.00021 | $0.00585 |
| Haiku 4.5 | $0.00011 | $0.00293 |
Grade A, and why
ux-information-architecture-audit 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 11d 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.

Information Architecture Audit Skill
What this skill changes vs. default behavior
By default, Claude critiques a structure by eyeballing the category names — it rarely tests whether the organization scheme matches how users actually seek, whether labels carry information scent before the click, whether the hierarchy's breadth/depth ratio forces click-tunneling, or whether users landing mid-site can orient at all. This audit forces four things: every finding names the violated IA principle; labels are tested for scent ("could a user predict the destination?"), consistency, and vocabulary fit; the structure is checked against the seeking modes it must serve, not just the browse-from-homepage path; and findings come severity-rated with concrete fixes — including which research method (card sort, search-log analysis, free listing) would settle a contested call.
This is an evaluative skill: it auto-runs whenever a sitemap, navigation structure, category system, or multi-screen flow is being reviewed — and as a validation step after generative skills that structure content (ux-navigation, ux-menus, ux-search).
Scope discipline. When invoked directly (the user named this audit), review only this concern — don't pull in sibling audits. It runs alongside other lenses only when an orchestrator (ux-design-review) or a generative skill calls it under docs/orchestration-policy.md, where it sits in Tier B — offered. Explicit scope always wins.
The framework — what to check and what a violation looks like
1. Organization scheme matches the user's task
Schemes are exact (alphabetical, chronological, geographical) or subjective (topical, task-oriented, audience, metaphor, hybrid). Exact schemes work only when users know the item's name; subjective schemes serve browsing and discovery. The choice follows from top user tasks, not from what's easiest to build.
Flag when: alphabetical ordering on content users browse by category (a spa listing services A–Z); chronological where users seek by topic; a metaphor scheme requiring users to learn the metaphor; a hybrid mixing many schemes deep in navigation (fine on a homepage, confusing at depth).
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-information-architecture-audit is a skill published in the GitHub repository Uxcel-Lab/product-skills (10 stars, last pushed 2mo ago), licensed MIT. It adds 105 tokens to every session and 2,927 once invoked, about $0.0005 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.
