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 | $0.00080 | $0.01664 |
| Opus 5 | $0.00040 | $0.00832 |
| Sonnet 5 | $0.00016 | $0.00333 |
| Haiku 4.5 | $0.00008 | $0.00166 |
Grade A, and why
frontend-slides 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.
How it starts
The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Slides
Self-contained HTML presentations: one file, inline CSS/JS, no build step, no dependencies. Every slide must fit one viewport with zero internal scrolling — that constraint drives nearly every other decision in this skill.
Before generating any slide HTML, read
references/style-presets.md for the mandatory viewport-fitting CSS base,
the density limits table, the preset catalog, and the CSS gotchas — those
details are not repeated in full here.
When to use
Building a talk deck, pitch deck, workshop deck, or internal presentation;
converting .ppt/.pptx into HTML; improving an existing HTML deck's
layout, motion, or typography; exploring presentation styles with a user who
doesn't know their preference yet.
Non-negotiables
- Zero dependencies — one self-contained HTML file, inline CSS/JS, unless the user explicitly wants a multi-file project.
- Viewport fit is mandatory — every slide fits one viewport, no internal scrolling, ever.
- Show, don't tell — generate visual previews instead of asking abstract style questions.
- Distinctive design — no generic purple-gradient, Inter-on-white, template-looking deck.
- Production quality — commented, accessible, responsive, performant.
Workflow
1. Detect mode
New presentation (topic/notes/draft) · PPT/PPTX conversion · enhancement of an existing HTML deck.
2. Discover content
Ask only what's needed: purpose (pitch/teaching/talk/internal update), length (short 5-10, medium 10-20, long 20+), content state (finished copy, rough notes, topic only). If the user has content, get it before styling.
3. Discover style through preview, not questionnaire
If the user already names a preset from references/style-presets.md, use
it directly — skip previews.
Otherwise: ask what feeling the deck should create (impressed, energized,
focused, inspired), then generate 3 single-slide preview files in
.ecc-design/slide-previews/, each self-contained and under ~100 lines of
slide content, showing typography/color/motion clearly. Ask which to keep
or what to mix. Use the mood-to-preset mapping in the reference file.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

frontend-slides is a skill published in the GitHub repository shennawardana23/skillme (2 stars, last pushed 14d ago), licensed Apache-2.0. It adds 80 tokens to every session and 1,664 once invoked, about $0.0004 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 2026-09-03.
