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 | $0.03072 | $0.03072 |
| Opus 5 | $0.01536 | $0.01536 |
| Sonnet 5 | $0.00614 | $0.00614 |
| Haiku 4.5 | $0.00307 | $0.00307 |
Grade A, and why
muxboard AGENTS.md 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 6d 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.

UX Principles: How Users Actually Behave
These principles govern how real humans interact with interfaces. They are observed behavior, not preferences. Apply them before, during, and after every design decision.
The Three Laws of Usability
-
Don't make me think. Every page should be self-evident. If a user stops to think "What do I click?" or "What does this mean?", the design has failed. Self-evident > self-explanatory > requires explanation.
-
Clicks don't matter, thinking does. Three mindless, unambiguous clicks beat one click that requires thought. Each step should feel like an obvious choice (animal, vegetable, or mineral), not a puzzle.
-
Omit, then omit again. Get rid of half the words on each page, then get rid of half of what's left. Happy talk (self-congratulatory text) must die. Instructions must die. If they need reading, the design has failed.
How Users Actually Behave
- Users scan, they don't read. Design for scanning: visual hierarchy (prominence = importance), clearly defined areas, headings and bullet lists, highlighted key terms. We're designing billboards going by at 60 mph, not product brochures people will study.
- Users satisfice. They pick the first reasonable option, not the best. Make the right choice the most visible choice.
- Users muddle through. They don't figure out how things work. They wing it. If they accomplish their goal by accident, they won't seek the "right" way. Once they find something that works, no matter how badly, they stick to it.
- Users don't read instructions. They dive in. Guidance must be brief, timely, and unavoidable, or it won't be seen.
Billboard Design for Interfaces
- Use conventions. Logo top-left, nav top/left, search = magnifying glass. Don't innovate on navigation to be clever. Innovate when you KNOW you have a better idea, otherwise use conventions. Even across languages and cultures, web conventions let people identify the logo, nav, search, and main content.
- Visual hierarchy is everything. Related things are visually grouped. Nested things are visually contained. More important = more prominent. If everything shouts, nothing is heard. Start with the assumption everything is visual noise, guilty until proven innocent.
- Make clickable things obviously clickable. No relying on hover states for discoverability, especially on mobile where hover doesn't exist. Shape, location, and formatting (color, underlining) must signal clickability without interaction.
- Eliminate noise. Three sources: too many things shouting for attention (shouting), things not organized logically (disorganization), and too much stuff (clutter). Fix noise by removal, not addition.
- Clarity trumps consistency. If making something significantly clearer requires making it slightly inconsistent, choose clarity every time.
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.

muxboard AGENTS.md is an instructions file published in the GitHub repository aanari/muxboard (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 3,072 tokens to every session, about $0.0154 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.
