description: Create branded PowerPoint templates (.pptx/.potx) by extracting brand styles from a website or assets, generating base slides, and applying themes/layouts with potxkit via MCP or CLI.

Brand PPTX Template Skill

When to use

Use when asked to build or refresh a company PowerPoint template based on a website or brand assets, and deliver both .pptx and .potx outputs.

Inputs to collect

  • •Brand source: website URL or provided brand assets (logo, colors, fonts).
  • •Output scope: slide types needed (title, section, content, etc.).
  • •Local working directory path (for potxkit access).
  • •Delivery format: .pptx only or .pptx + .potx.

Environment model (generic)

Two environments are common:

  • •Agent runtime: where you can generate files (e.g., pptxgenjs, scripts).
  • •User local machine: where potxkit runs (MCP or CLI) and files live.

If the environments differ, always:

  1. •Generate base template in the agent runtime.
  2. •Transfer to local (download/present file).
  3. •Use potxkit on the local machine to apply theme + layouts.

Workflow (high level)

Phase 1: Brand extraction

  • •Use a browser MCP to extract colors, fonts, and logo.
  • •Capture UI patterns: light/dark sections, accent usage, card styles.
  • •If blocked, ask for brand assets or a style guide.

Reference: references/brand-extraction.js for a browser snippet.

Variant chooser (light vs dark)

Decide on a template mood before building slides:

  • •Light: default for business decks; white/very light background with dark text.
  • •Dark: good for technical or cinematic decks; dark background with light text.

If the brand site uses both, pick one for the base template and keep the other for section/cover layouts.

Phase 2: Map to PowerPoint theme slots

Map to theme keys:

  • •dark1, light1, dark2, light2
  • •accent1–accent6, hlink, folHlink
  • •majorFont, minorFont

Phase 3: Build base slides

Create a clean base deck with the needed slide types. Recommended defaults:

  • •Title, section, content, two-column, grid, metrics, quote, closing.
  • •Keep layout shapes clean and consistent; avoid hard-coded colors where possible.

Reference: references/pptxgenjs-starter.js for a starting scaffold. Optional script: scripts/scaffold_deck.js to generate a minimal base deck:

bash
node scripts/scaffold_deck.js --variant light --company "Acme Co" --out template-base.pptx

Phase 4: Apply theme + layouts with potxkit

Use potxkit via MCP or CLI:

  • •set_colors or apply-palette
  • •set_fonts
  • •set_theme_names
  • •make_layout from each base slide
  • •validate

Phase 5: Deliver

  • •Provide .pptx and .potx outputs.
  • •Confirm template behaves correctly in PowerPoint.

Guardrails

  • •Prefer theme-driven colors/fonts instead of per-shape overrides.
  • •Keep font sizes sane (titles 36–44 pt, body 14–18 pt).
  • •If outputs are generated in a container, always transfer to local before potxkit.
