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 | $0.00031 | $0.01180 |
| Opus 5 | $0.00015 | $0.00590 |
| Sonnet 5 | $0.00006 | $0.00236 |
| Haiku 4.5 | $0.00003 | $0.00118 |
Grade A, and why
add-slide 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Slide
You are helping the user add a new slide to an existing presentation.
Step 1: Identify Target Presentation
List the presentation folders in presentations/ (excluding _template). Ask the user which presentation they want to add a slide to. If there's only one, confirm it.
Step 2: Show Current Slides
Read the presentation's index.md and display a numbered list of existing slides:
1. [title] Opening Slide
2. [content] Key Points
3. [metrics] Results
Ask the user where to insert the new slide (after which slide number, or at the end).
Step 3: Choose Template
Ask the user which template to use. Show this reference:
| Template | Best For |
|---|---|
title |
Opening slide with logo, title, subtitle, author |
section |
Section divider for organizing chapters |
content |
Standard bullet points with optional lead text |
center |
Image or statement centered inside the slide — correct choice for image-only slides |
hero |
Full-browser-background image (bleeds outside slide) with headline text — NOT for image-only slides |
metrics |
2-4 key statistics with colored cards |
comparison |
Before/after two-column table |
columns |
Side-by-side content columns |
split |
1/3 image + 2/3 content |
split-wide |
1/3 content + 2/3 image |
quote |
Testimonial with attribution |
timeline |
Horizontal timeline with events |
funnel |
Progressive narrowing funnel |
table |
Data table with headers |
code |
Code snippet with syntax highlighting |
image-overlay |
Full-browser-background image (bleeds outside slide) with positioned text box — NOT for image-only slides |
agenda |
Clickable table of contents |
diagram |
D2 diagram compiled to inline SVG |
Step 3b: Image Placement and Sourcing (image slides only)
If the chosen template involves an image (center, hero, image-overlay, split, split-wide), work through these two decisions before writing any YAML.
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.

add-slide is a skill published in the GitHub repository Chrisissorry/lazyslides (5 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 1,180 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.
