Token cost

What it costs to keep this loaded

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00031 $0.01180
Opus 5.5 $0.00012 $0.00472

Security

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 2mo 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.

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.
