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 | $0.00043 | $0.00269 |
| Opus 5 | $0.00022 | $0.00134 |
| Sonnet 5 | $0.00009 | $0.00054 |
| Haiku 4.5 | $0.00004 | $0.00027 |
Grade A, and why
html-slide-prompt 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 8d 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
HTML Slide Prompt
Use this skill for commands like:
$html-slide-prompt- "create html_slide_prompts.json"
- "write implementation prompts for each HTML slide"
- "convert the slide plan into build instructions"
Goal
Create html_slide_prompts.json: one implementation-ready instruction object per slide.
Inputs
DESIGN.mdslide_plan.json- source files if facts need verification
Required Output
Return valid JSON only. For every slide include:
- slide number
- page family
- slide title
- HTML layout family
- content blocks
- semantic structure
- CSS layout instructions
- responsive behavior
- chart/table/icon instructions
- assets required
- accessibility notes
- anti-patterns to avoid
Hard Rules
- Do not render final HTML in this step.
- Do not use GPT image-generation language unless an image asset is explicitly needed.
- Keep instructions buildable with normal HTML/CSS/JS.
- Stop after
html_slide_prompts.jsonunless the user explicitly asks to continue.
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.

html-slide-prompt is a skill published in the GitHub repository bytonylee/future-slide (146 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 269 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 2026-08-30.
