What it does

Utility Slideshow Creator is an agent skill from product-on-purpose/pm-skills. Generates professional presentations from a JSON deck specification using 18 slide types with dark/light variants, content-to-layout decision logic, and calibrated character limits. Ships with a default professional theme.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `HISTORY.md`, `evals/trigger-fixtures.json` and `references/EXAMPLE.md`).

It sits in Documents & Office, covering Slides and decks. It works with Microsoft PowerPoint. The repository describes itself as: 68 plug-and-play, best-practice product management skills for AI agents: 30 Triple Diamond phase + 11 foundation + 12 utility + 15 tool (Foundation Sprint + Design Sprint). Plus… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Slides and decks

Example prompts

  • “Use the utility-slideshow-creator skill to generate professional presentations from a JSON deck specification using 18 slide types with dark/light…”
  • “/utility-slideshow-creator”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Spec phase (Claude) - Read the content brief, select slide types using decision logic, write a JSON deck specification. Content slots have…
  2. Generation phase (Local script) - Run node scripts/generate-deck.js deck-spec.json to produce .pptx. Optionally run node…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cef1a9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Utility Slideshow Creator loads about 1.6k tokens when it runs, and up to ~7.5k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 665 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Slideshow Creator

Generate professional presentations (.pptx and .pdf) from a JSON deck specification. Zero design decisions at generation time - Claude selects slide types and fills content slots; all visual properties are pre-decided by the theme.

When to Use

  • Creating slide decks for stakeholder updates, product reviews, team presentations
  • Generating professional .pptx files from content briefs
  • Producing consistent presentations without manual formatting
  • Exporting presentations to PDF for sharing or archiving

When NOT to Use

  • Creating complex data visualizations (use dedicated charting tools)
  • Building interactive web presentations (this produces .pptx, not HTML)
  • Editing existing PowerPoint files (this creates new decks from scratch)

How It Works

Two-phase architecture:

  1. Spec phase (Claude) - Read the content brief, select slide types using decision logic, write a JSON deck specification. Content slots have character limits calibrated to prevent overflow. This is the only phase that costs tokens.
  2. Generation phase (Local script) - Run node scripts/generate-deck.js deck-spec.json to produce .pptx. Optionally run node scripts/export-pdf.mjs deck-spec.json for PDF. Deterministic rendering, zero token cost.

Both outputs come from the same JSON spec, so .pptx and .pdf always match.

Instructions

  1. Read the content brief - Understand topic, audience, length, specific requirements
  2. Plan the deck - Select slide types using the decision logic table. Assign dark/light variants for visual rhythm (alternate to avoid monotony).
  3. Write the JSON deck specification - Fill content slots, respecting character limits from references/slide-types.md
  4. Run the generation script - node scripts/generate-deck.js deck-spec.json
  5. Optionally export PDF - node scripts/export-pdf.mjs deck-spec.json output.pdf
  6. Report the output - Tell the user where the file(s) are

Output Contract

  • Planning artifact: JSON deck specification (the file Claude writes)
  • Final output: .pptx file (+ optional .pdf), generated locally from the spec
  • Quality gate: All items in the quality checklist pass

Quality Checklist

  • Every slide has a valid type key (one of the 18 defined types)
  • All content slots respect character limits from references/slide-types.md
  • Dark/light variants alternate for visual rhythm (no 3+ consecutive same-variant slides)
  • Deck has a title slide (first) and a closing slide (last)
  • Section dividers separate distinct topics in decks > 6 slides
  • Speaker notes included for key slides (stats, highlights, transitions)
  • JSON is valid (no trailing commas, proper quoting, correct nesting)
  • Color values are valid theme tokens or 6-character hex strings (no # prefix)
