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 | $0.00080 | $0.01527 |
| Opus 5.5 | $0.00032 | $0.00611 |
| Sonnet 5.5 | $0.00016 | $0.00305 |
| Haiku 4.5 | $0.00008 | $0.00153 |
Grade A, and why
s4h-design-user-needs 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.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design: User Needs
The most common design failure is building the wrong thing well. People don't articulate needs — they articulate solutions. "I want a faster horse," "I need a bigger inbox," "give me more options." These are requests framed as solutions to problems the user hasn't quite stated. A designer who takes them at face value will build a faster horse, a bigger inbox, more options — and miss the underlying need entirely.
Clayton Christensen's jobs-to-be-done framework makes the shift explicit: people don't buy products, they hire them to do a job. Understanding the job — not the product request — is the designer's actual brief. Don Norman extended this with the distinction between stated needs (what people say), observed needs (what people do), and latent needs (what people don't yet know they need but would recognise immediately if you showed them). All three matter. Only one of them is given to you directly.
This skill works through all three levels, using structured inquiry to separate the real need from the stated proxy and surface the design target that actually matters.
Your Process
Step 1: State the Request Write down exactly what was asked for, in the words it was stated. Preserve the phrasing — the precise language reveals how the person is framing the problem.
Framing check: Confirm the request and the context in which it arose before continuing. State what you've identified — the stated request and the situation it comes from — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the request and its context]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different situation than read; incorporate the correction before proceeding
Step 2: Decompose the Job Apply jobs-to-be-done decomposition. For the stated request, identify:
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.

s4h-design-user-needs is a skill published in the GitHub repository human-avatar/skills-for-humanity (236 stars, last pushed 3mo ago), licensed MIT. It adds 80 tokens to every session and 1,527 once invoked, about $0.0003 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.
