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 5.1 | $0.00038 | $0.01855 |
| Opus 5 | $0.00019 | $0.00928 |
| Sonnet 5 | $0.00008 | $0.00371 |
| Haiku 4.5 | $0.00004 | $0.00186 |
Grade A, and why
ai-output-design 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Output Design
The Law
AI OUTPUT IS NOT STATIC CONTENT.
"Just render the markdown" and "the model formats it" both ship walls of unstyled text with no hierarchy, no confidence signals, and no accessibility layer.
Defined rendering rules + typographic hierarchy + confidence signals IS output design.
When to Use
Trigger when:
- Designing how model responses are displayed in any UI surface
- Adding markdown rendering to an AI response container
- Designing how structured data from the model (tables, lists, code) is presented
- Designing the visual treatment for uncertainty or low-confidence responses
- Reviewing whether existing AI output rendering is production-quality
When NOT to Use
- Output that is always structured JSON consumed by the system, not displayed to users
- Backend pipelines where no human reads the model output directly
The Output Rendering Stack
1 — Markdown Rendering
Model responses contain markdown. Define which elements to render and how:
| Element | Render as | Notes |
|---|---|---|
# H1 |
Use sparingly in responses — demote to H3 | H1 inside a response clashes with page hierarchy |
**bold** |
<strong> |
Full weight only; no extra color |
_italic_ |
<em> |
Used for emphasis, not decoration |
`inline code` |
<code class="inline"> |
Monospace, tinted background |
```code block``` |
Syntax-highlighted <pre><code> |
Language label, copy button, max-height with scroll |
- list |
<ul> with custom bullet |
0.5rem gap between items |
1. ordered |
<ol> |
Numbers bold, content regular weight |
> blockquote |
Left bar, muted text | Use for citations or model asides |
| ` | table | ` |
--- |
<hr> |
Thin, muted; use sparingly |
Rules:
- Never render raw HTML from model output (XSS risk — sanitise or use a safe renderer)
- H1 and H2 inside responses should be demoted (H1 → H3, H2 → H4) to preserve page hierarchy
- Long code blocks: max-height 400px, scroll inside, copy button visible without scrolling
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.
- 10d ago First seen · 188 lines · 38 tokens per session scan A 110e29e44d12
ai-output-design is a skill published in the GitHub repository RBraga01/builder-design (2 stars, last pushed 2mo ago), licensed MIT. It adds 38 tokens to every session and 1,855 once invoked, about $0.0002 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.
