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 | $0.00127 | $0.01861 |
| Opus 5 | $0.00063 | $0.00931 |
| Sonnet 5 | $0.00025 | $0.00372 |
| Haiku 4.5 | $0.00013 | $0.00186 |
Grade A, and why
design-express 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 8d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Express (the On-Ramp)
The full Designpowers pipeline is powerful and the right tool for real work — but it's a lot to commit to in someone's first three minutes, especially for a designer new to the terminal. Express is the on-ramp: the fastest possible loop from "I have a thing" or "I want a small thing" to "here's something useful," in plain language, then a clear door into the full team.
Express is a gateway, not a bypass. Designpowers' whole thesis is process over guessing — its anti-patterns explicitly name "this is too small to need discovery" and "let me just quickly build this" as failures. Express does not contradict that. It is a taster that pulls people into the process, with three lines held firm:
- Accessibility is never skipped. It's "not a phase" — it stays in even here. No express output ships an inaccessible result.
- Express output is always labelled "a starting point, not a finished design." Never presented as done.
- The upward bridge is the point. Every express result ends by offering the full team. Conversion into the real workflow is the goal, not a quick exit from it.
When to Use
- A first-time user who seems hesitant, or explicitly wants something quick ("just take a quick look", "can you knock together a…", "I only have a minute")
- A designer new to the terminal who freezes at the full pipeline
- Offered proactively to first-time users right after the guided walkthrough (see
using-designpowers)
Do NOT use for:
- Returning users (taste profile exists) — they know the system; route them to the Build or Review lane.
- Real project work — once the user is engaged, move up to the full pipeline. Express is the first two minutes, not the whole job.
If you're unsure whether someone wants express or the full thing, default to offering express to first-timers and the full lanes to everyone else.
Plain-Language Rule (applies to everything below)
Express talks like a helpful colleague, not a spec.
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.
- 8d ago First seen · 135 lines · 127 tokens per session scan A abe60f184d2e
design-express is a skill published in the GitHub repository Owl-Listener/designpowers (241 stars, last pushed 2mo ago), licensed MIT. It adds 127 tokens to every session and 1,861 once invoked, about $0.0006 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.
