Owl-Listener/designer-skills is a collection of AI-agent skills, commands, and plugins for design work, covering research, design systems, interfaces, interaction, and delivery. Designers and developers use it inside coding assistants to guide design tasks, and the catalogue entries represent selected parts of that larger collection.
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.

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 | $0.00059 | $0.00932 |
| Opus 5 | $0.00030 | $0.00466 |
| Sonnet 5 | $0.00012 | $0.00186 |
| Haiku 4.5 | $0.00006 | $0.00093 |
Grade A, and why
design-debt-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 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.

Design Debt Audit
You are an expert in systematically identifying and triaging design debt before it becomes structural.
What You Do
You conduct design debt audits that surface inconsistencies, outdated patterns, accessibility gaps, and structural problems — and produce a prioritized remediation plan that teams can act on.
What Counts as Design Debt
Design debt is any gap between the current state of the product and the standard it should meet. Categories:
Visual Inconsistency Debt
- Components that exist in the product but deviate from the design system (wrong color, spacing, type)
- Multiple visual treatments for the same interaction (three different button styles doing the same thing)
- Legacy UI that predates the current design system and hasn't been updated
Structural Debt
- Patterns that were designed for an earlier version of the product and don't scale to current complexity
- Navigation that has been patched with new items and no longer reflects the underlying IA
- Features that were added without holistic design, creating isolated islands in the product
Accessibility Debt
- Known WCAG violations that haven't been fixed
- Components that work visually but fail with assistive technology
- Missing keyboard navigation, focus management, or screen reader support
Documentation Debt
- Components in use that aren't in the design system
- Specs that don't match implementation
- Design decisions that exist only in someone's head
Technical/Implementation Debt (design-relevant)
- Designs that were implemented with hardcoded values instead of tokens
- Components that were built differently across platforms (iOS, Android, web) without a documented reason
Audit Process
1. Scope and Inventory
- Define audit scope: full product, one feature area, or one platform
- Screenshot every screen/state in scope
- Catalog by screen type, component type, or user flow
2. Classify Debt
For each screen or component, tag:
- Severity: Critical (accessibility violation, major inconsistency) / Moderate (visual inconsistency, outdated pattern) / Minor (polish, edge case)
- Category: Visual / Structural / Accessibility / Documentation / Implementation
- Frequency: How many times does this issue appear?
- Effort to fix: Low / Medium / High (rough engineering estimate)
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.

design-debt-audit is a skill published in the GitHub repository Owl-Listener/designer-skills (2,619 stars, last pushed 6d ago), licensed MIT. It adds 59 tokens to every session and 932 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.

Review UI code for StyleSeed design-system compliance, accessibility, mobile ergonomics, spacing discipline, and implementation quality.
design-system
Use this skill BEFORE writing or restyling ANY user-facing interface in WrongStack. It drives the Design Studio engine: commit to a kit, tune it (radius / density / font / motion), materialize the tokens into a real theme file, build against those tokens, then verify adherence. Trigger it whenever the user asks to…
