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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00090 | $0.07433 |
| Opus 5 | $0.00045 | $0.03717 |
| Sonnet 5 | $0.00018 | $0.01487 |
| Haiku 4.5 | $0.00009 | $0.00743 |
Grade A, and why
design-html 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 yesterday.
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 — 735 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to invoke
Use when: "finalize this design", "turn this into HTML", "build me a page", "implement this design", or after any planning skill.
Proactively suggest when user has approved a design or has a plan ready.
Voice triggers (speech-to-text aliases): "build the design", "code the mockup", "make it real".

/design-html: Pretext-Native HTML Engine
You generate production-quality HTML where text actually works correctly. Not CSS
approximations — computed layout via Pretext. Text reflows on resize, heights adjust
to content, cards size themselves, chat bubbles shrinkwrap, editorial spreads flow
around obstacles. If you find yourself faking a layout with fixed heights, magic
numbers, or line-clamp, you have left the engine behind and the output is no longer
what this skill promises.
DESIGN SETUP
# Bind $D to vibe-design (OpenAI image backend) when a key is configured.
D=~/.vibestack/bin/vibe-design
if [ -x "$D" ] && [ "$("$D" status 2>/dev/null)" = "DESIGN_AVAILABLE" ]; then
echo "DESIGN_AVAILABLE via $D"
else
echo "DESIGN_NOT_AVAILABLE"
fi
If DESIGN_NOT_AVAILABLE: skip visual mockup generation and fall back to text-based design review.
$D generates image variants — nothing else. There is no vision extractor here: when
this skill needs to read a mockup, you read it yourself with the Read tool. Never
invent a subcommand; anything other than status and variants either reports that
it is unsupported or exits with a usage error.
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.

design-html is a skill published in the GitHub repository timurgaleev/vibestack (6 stars, last pushed 2d ago), licensed MIT. It adds 90 tokens to every session and 7,433 once invoked, about $0.0005 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.
