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 | $0.00053 | $0.02584 |
| Opus 5 | $0.00026 | $0.01292 |
| Sonnet 5 | $0.00011 | $0.00517 |
| Haiku 4.5 | $0.00005 | $0.00258 |
Grade A, and why
design-taste 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 10d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Taste
Process discipline produces correct design. Taste produces design people love. This skill captures the subjective, aesthetic dimension that no checklist can replace — the difference between a design that works and one that sings.
Welcome Gate
BEFORE calibrating taste, check whether the Designpowers welcome sequence has been shown this session. If the user has not yet seen the welcome (the bird, the greeting, and the walkthrough offer), you MUST invoke the using-designpowers skill FIRST and complete the welcome sequence before returning here. The bird must appear before any work begins. No exceptions.
Why This Exists
The Designpowers workflow verifies that designs are:
- Aligned to the brief and plan
- Accessible and inclusive
- Consistent with design principles
But none of that answers: Is it beautiful? Does it feel right? Is it elevated?
Taste is the gap between compliance and craft. This skill gives agents a shared vocabulary and reference point for the aesthetic quality the project demands.
When to Use
- After strategy, before design work begins (taste calibration)
- When the user shares design references, screenshots, or inspiration
- When the design-lead needs aesthetic direction beyond what the brief provides
- When the design-critic needs to evaluate craft quality, not just plan compliance
- When something "works" but doesn't feel right — and you need to articulate why
Process
Step 1: Gather Taste Inputs
This step is a conversation, not a form. Actively prompt the user — don't wait for them to volunteer. Most people have strong taste but haven't been asked the right questions. Your job is to draw it out.
1a: Check for an Existing Design System
Before asking subjective questions, check what already exists:
- "Do you have an existing design system, style guide, or component library?"
- "Can you point me to your tokens, brand guidelines, or any visual standards?"
- "Is there a Figma file, Storybook, or design system documentation I should look at?"
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-taste is a skill published in the GitHub repository Owl-Listener/designpowers (243 stars, last pushed 2mo ago), licensed MIT. It adds 53 tokens to every session and 2,584 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.
