What is lazyslides CLAUDE.md?

Project instructions for LazySlides, a tool that turns YAML text files into Reveal.js slide presentations. They describe how to create, edit, preview, validate, and renumber slides.

Use them when creating a presentation, adding or editing slides, validating YAML, previewing the result, or working with the project's commands and templates.

They give a coding agent the project-specific workflow and checks needed to change presentations consistently.

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.

Model	Per session	Once invoked
Fable 5.1	$0.04714	$0.04714
Opus 5	$0.02357	$0.02357
Sonnet 5	$0.00943	$0.00943
Haiku 4.5	$0.00471	$0.00471

Security

Grade A, and why

lazyslides CLAUDE.md 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

LazySlides turns structured YAML into professional slide decks. Presentations are authored in YAML, rendered through Nunjucks templates into Reveal.js, and styled with Tailwind CSS 4.x. Distributed as an npm package (lazyslides) with an Eleventy plugin and CLI.

Presentation Authoring Workflow

Creating a new presentation

Start with an outline — fill in presentations/_template/outline.md or use /create-outline
Run /new-presentation — the slash command guides you through the full process
Or manually: create presentations/{name}/index.md with YAML frontmatter

Adding slides

Run /add-slide — picks template, gathers content, inserts at the right position
Or manually: add a new - template: ... entry to the slides: array

Editing slides

Read the presentation's index.md
Modify the YAML for the target slide
Run pnpm run validate to verify
Run pnpm run dev to preview

Validating

pnpm run validate    # check all presentations
pnpm run renumber    # update slide comment numbers

YAML Schema Reference

All presentations use this structure:

---
title: Deck Title            # required
description: Subtitle
author: Speaker Name
theme: default               # LazySlides theme name
transition: slide            # global transition: none, fade, slide, convex, concave, zoom
progress: true
slideNumber: true
show_footer: true            # show footer on slides (default: true, set false to hide globally)
math: true                   # enable KaTeX math rendering (opt-in)
slides:                      # required — array of slide objects
  - template: content        # required on every slide
    title: Slide Title
    # ... template-specific fields
    hide_footer: true        # optional — hide footer on this slide (default: false)
    notes: |                 # optional speaker notes (all templates)
      What to say during this slide

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.
