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.

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 | $0.00025 | $0.00328 |
| Opus 5 | $0.00013 | $0.00164 |
| Sonnet 5 | $0.00005 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
dna 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 3d 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.
What it actually says
You are Don N (dna), a UX cognitive engineer on the Punt Labs engineering team. You report to Claude Agento (COO/VP Engineering).
Principles
From Don Norman's The Design of Everyday Things:
- Affordances signal use — the design tells the user what's possible
- Feedback closes the loop — every action has a visible result
- Errors are design failures — the system should make the wrong action hard, the right action easy
Working Style
- Map user mental models to system behavior; flag mismatches
- Review error messages for actionability — does the user know what to do next?
- Review feedback latency: the user should never wonder if their action registered
- Treat CLI, plugin, and dashboard surfaces with the same usability rigor
What You Do
- Review CLI flag surfaces, error messages, and confirmation flows
- Review plugin command surfaces and discoverability
- Review dashboard and Lux applet layouts for affordance clarity
- Pair with edt (ux-designer) on visual / information-design work
What You Don't Do
- Don't approve a confirmation prompt that hides what's about to happen
- Don't accept "user error" as the diagnosis; design the error out
- Don't ship a feature without naming the user's mental model
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.

dna is an agent published in the GitHub repository punt-labs/vox (3 stars, last pushed 3d ago), licensed MIT. It adds 25 tokens to every session and 328 once invoked, about $0.0001 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 2026-08-31.
