lazyslides: Skill for Claude Code

.claude/skills/add-template/SKILL.md

add-template is a skill for Claude Code from Chrisissorry/lazyslides. It costs 31 tokens per session (754 once invoked), scanned A, original, MIT.

A guide for adding a custom slide layout to a LazySlides presentation. It explains how to create the Nunjucks template file and its CSS.

In plain words
What is it for?
Use it to choose a starting layout, name a new template, and create its `.njk` file in `_includes/slides/`.
Why use it?
It helps when the built-in slide layouts do not match the presentation you need. It gives the new layout a consistent structure and required content fields.

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.

Security

Grade A, and why

add-template 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 9d 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 Template

You are helping the user create a custom slide template for their LazySlides project.

Step 1: Gather Requirements

Ask the user:

  • What should the template do? (purpose, layout idea)
  • What content fields does it need? (titles, text, images, lists, etc.)
  • Any specific layout or styling requirements?

Step 2: Choose a Name

Help the user pick a kebab-case name for the template (e.g. icon-grid, two-images, photo-grid). The name must not conflict with the 19 built-in templates: title, section, content, center, hero, metrics, comparison, columns, quote, image-overlay, code, timeline, funnel, split, split-wide, table, agenda, diagram.

Step 3: Pick a Starting Point

Read the existing templates in _includes/slides/ and suggest the closest built-in template as a base to adapt from. Show the user the docblock and structure of the suggested template. They can also choose to start from scratch.

Step 4: Create the Template File

Generate _includes/slides/<name>.njk following the standard pattern:

{#
  TEMPLATE: <name> — <short description>

  Fields:
    - field_name* — description (required)
    - field_name — description (optional)

  Usage:
    - template: <name>
      field_name: "value"
#}

<section class="slide-<name>">
  <div class="slide-body">
    {% if slide.title %}
    <div class="slide-header">
      <h2>{{ slide.title }}</h2>
    </div>
    {% endif %}

    <div class="slide-content">
      {# Template-specific content here #}
    </div>
  </div>

  {% if slide.notes %}
  <aside class="notes">{{ slide.notes }}</aside>
  {% endif %}

  {% include "slides/_footer.njk" %}
</section>

Key conventions to follow:

  • Wrap everything in <section class="slide-<name>">
  • Use slide-body > slide-header + slide-content structure
  • Access slide data via slide.fieldName
  • Include speaker notes block and footer include
  • Use existing CSS utility classes from the design system where possible

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.
