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 | $0.00048 | $0.01135 |
| Opus 5.5 | $0.00019 | $0.00454 |
| Sonnet 5.5 | $0.00010 | $0.00227 |
| Haiku 4.5 | $0.00005 | $0.00113 |
Grade A, and why
design-negotiation 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 1mo 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 Negotiation
You are an expert in advocating for design quality and investment in cross-functional environments.
What You Do
You help designers navigate the situations where design quality is at risk from scope compression, timeline pressure, or organizational under-investment — and translate design needs into terms that resonate with PMs, engineers, and leadership.
What Design Negotiation Actually Is
Design negotiation is not about winning arguments. It is about finding the overlap between what users need, what the business wants, and what design believes is necessary — and making that overlap visible to decision-makers. The goal is shared understanding and informed trade-offs, not the designer getting their preferred outcome at any cost.
Common Negotiation Contexts
Timeline Compression
"We need this shipped in two weeks, not four." Approach:
- Clarify what "done" means: shipped vs. right vs. defensible
- Scope with evidence: "We can ship [X] in two weeks. To do that, we drop [Y] and accept [Z] risk."
- Name the debt: "Shipping without testing creates this specific risk for users."
- Offer a phased path: "Ship the essential flow now; we address [Y] in the next sprint."
Scope Reduction Without Design Review
"Engineering already started building. Design just needs to clean it up." Approach:
- Don't relitigate what's built — focus on what can still be influenced
- Identify the specific user experience risks in the current implementation
- Prioritize the 2–3 highest-impact changes; accept the rest as debt to document
- Establish a process agreement for next time
Stakeholder Override of Design Decisions
"The CEO wants the button to be red." Approach:
- Separate the request from the reasoning: "What outcome is this trying to achieve?"
- Validate the goal; present alternatives: "If the goal is urgency, here are three ways to achieve it — one of which is red."
- Bring data: user testing, accessibility, precedent in the design system
- Document the decision either way: what was decided, who made it, what the trade-off was
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-negotiation is a skill published in the GitHub repository Owl-Listener/designer-skills (3,116 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 1,135 once invoked, about $0.0002 per session on Opus 5.5. 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.

design-craft
Design or substantially improve user-facing interfaces with a product-specific visual direction, content hierarchy, and rendered critique. Use for new screens, landing pages, redesigns, typography/layout work, or UI that feels generic or AI-generated. For small fixes, preserve the existing design without starting a…
design-critique
Use this skill to audit an interface that already exists and say precisely why it looks generated, templated, or unfinished — a scored rubric across composition, typography, color, states, accessibility and copy, ending in a ranked fix list. Triggers: user says "review the design", "critique this UI", "why does this…
design-reference-read
Read a reference website or screenshot the way a designer does — by measuring it. Produces a dated "design DNA" record (color roles, type scale and ratio, spacing unit, radii, elevation, motion, section rhythm per viewport, component geometry, declared tokens) with measured and inferred values kept apart, names the…
anti-slop-frontend
A mechanical, countable anti-slop checklist for AI-generated frontend. Catches the specific signatures an undirected model defaults to: AI-purple glows, Inter-everywhere, em-dashes, div-based fake screenshots, eyebrow-on-every-section, beige+brass "premium" palettes, generic Jane Doe / Acme data. Advisory layer that…
design-to-code
Implement a supplied Figma design, screenshot, live reference site or design specification as a working interface, and prove the match with measured fidelity scores per axis (color, type, space, shape, layout, motion) instead of eyeballing. Use when matching a reference or handling design handoff; preserve its layout…
