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 | $0.00063 | $0.01470 |
| Opus 5 | $0.00032 | $0.00735 |
| Sonnet 5 | $0.00013 | $0.00294 |
| Haiku 4.5 | $0.00006 | $0.00147 |
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 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.
This is a copy
94% identical to frontend-slides — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Slides
Create zero-dependency, animation-rich HTML presentations that run entirely in the browser.
Inspired by the visual exploration approach showcased in work by zarazhangrui.
When to Activate
- Creating a talk deck, pitch deck, workshop deck, or internal presentation
- Converting
.pptor.pptxslides into an HTML presentation - Improving an existing HTML presentation's layout, motion, or typography
- Exploring presentation styles with a user who does not know their design preference yet
Non-Negotiables
- Zero dependencies: default to one self-contained HTML file with inline CSS and JS.
- Viewport fit is mandatory: every slide must fit inside one viewport with no internal scrolling.
- Show, don't tell: use visual previews instead of abstract style questionnaires.
- Distinctive design: avoid generic purple-gradient, Inter-on-white, template-looking decks.
- Production quality: keep code commented, accessible, responsive, and performant.
Before generating, read STYLE_PRESETS.md for the viewport-safe CSS base, density limits, preset catalog, and CSS gotchas.
Workflow
1. Detect Mode
Choose one path:
- New presentation: user has a topic, notes, or full draft
- PPT conversion: user has
.pptor.pptx - Enhancement: user already has HTML slides and wants improvements
2. Discover Content
Ask only the minimum needed:
- purpose: pitch, teaching, conference 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, ask them to paste it before styling.
3. Discover Style
Default to visual exploration.
If the user already knows the desired preset, skip previews and use it directly.
Otherwise:
- Ask what feeling the deck should create: impressed, energized, focused, inspired.
- Generate 3 single-slide preview files in
.ecc-design/slide-previews/. - Each preview must be self-contained, show typography/color/motion clearly, and stay under roughly 100 lines of slide content.
- Ask the user which preview to keep or what elements to mix.
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.

spotpatch
A development workflow for React that connects a selected page element to its JSX or TSX source code and gathers context for review.
design-patterns
Detect, suggest, and evaluate GoF design patterns in TypeScript/JavaScript codebases. Use when refactoring code, applying singleton/factory/observer/strategy patterns, reviewing pattern quality, or finding stack-native alternatives for React, Angular, NestJS, and Vue.

Diagnose React runtime performance with React Doctor traces, live render outlines, Long Animation Frames, interaction timing, and component render evidence. Use when invoked as /performance for a slow interaction, unexpected re-renders, or a measured before-and-after comparison.
ring:creating-handoffs
Creating a handoff document that captures session state (completed work, decisions, open items, next steps) and delivering it via Plan Mode so the user gets the native 'clear context and continue implementing' resume option. Use when ending a session, when context grows large, or the user says 'handoff', 'save…
