What it does

Slides is an agent skill from fcakyon/claude-codex-settings. Create and edit presentation slide decks (.pptx) with PptxGenJS, bundled layout helpers, and render/validation utilities. Use when tasks involve building a new PowerPoint deck, recreating slides from screenshots/PDFs/reference decks, modifying slide content while preserving editable output, adding charts/diagrams/visuals, or diagnosing layout issues such as overflow, overlaps, and font substitution.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including scripts, reference files and assets (for example `assets/pptxgenjs_helpers/code.js`, `assets/pptxgenjs_helpers/image.js` and `assets/pptxgenjs_helpers/index.js`).

It sits in Documents & Office, covering Slides and decks and PowerPoint presentations. It works with Microsoft PowerPoint and python-pptx. The repository describes itself as: Battle-tested Claude Code, OpenAI Codex, Cursor configs, plugins, hooks and agents with Kimi, MiniMax and GLM API support. The licence is MIT.

When your agent uses it

  • Tasks involve building a new PowerPoint deck
  • Recreating slides from screenshots/PDFs/reference decks
  • Modifying slide content while preserving editable output
  • Adding charts/diagrams/visuals

Example prompts

  • “/slides”

Requirements

  • Python 3
  • Node.js

Workflow steps

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

  1. Inspect the request and determine whether you are creating a new deck, recreating an existing deck, or editing one.
  2. Set the slide size up front. Default to 16:9 (LAYOUT_WIDE) unless the source material clearly uses another aspect ratio.
  3. Copy assets/pptxgenjs_helpers/ into the working directory and import the helpers from there.
  4. Build the deck in JavaScript with an explicit theme font, stable spacing, and editable PowerPoint-native elements when practical.
  5. Run the bundled scripts from this skill directory or copy the needed ones into the task workspace. Render the result with…
  6. Run slides_test.py for overflow checks when slide edges are tight or the deck is dense.
  7. Deliver the .pptx, the authoring .js, and any generated assets that are required to rebuild the deck.

What it can do on your machine

Read from SKILL.md and the folder at commit a035b4e. 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

    Ships 5 files in scripts/ (JavaScript and Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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

Slides loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 502 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

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); the scripts in this folder are not scanned.

Slides

Overview

Use PptxGenJS for slide authoring. Do not use python-pptx for deck generation unless the task is inspection-only; keep editable output in JavaScript and deliver both the .pptx and the source .js.

Keep work in a task-local directory. Only copy final artifacts to the requested destination after rendering and validation pass.

Bundled Resources

  • assets/pptxgenjs_helpers/: Copy this folder into the deck workspace and import it locally instead of reimplementing helper logic.
  • scripts/render_slides.py: Rasterize a .pptx or .pdf to per-slide PNGs.
  • scripts/slides_test.py: Detect content that overflows the slide canvas.
  • scripts/create_montage.py: Build a contact-sheet style montage of rendered slides.
  • scripts/detect_font.py: Report missing or substituted fonts as LibreOffice resolves them.
  • scripts/ensure_raster_image.py: Convert SVG/EMF/HEIC/PDF-like assets into PNGs for quick inspection.
  • references/pptxgenjs-helpers.md: Load only when you need API details or dependency notes.

Workflow

  1. Inspect the request and determine whether you are creating a new deck, recreating an existing deck, or editing one.
  2. Set the slide size up front. Default to 16:9 (LAYOUT_WIDE) unless the source material clearly uses another aspect ratio.
  3. Copy assets/pptxgenjs_helpers/ into the working directory and import the helpers from there.
  4. Build the deck in JavaScript with an explicit theme font, stable spacing, and editable PowerPoint-native elements when practical.
  5. Run the bundled scripts from this skill directory or copy the needed ones into the task workspace. Render the result with render_slides.py, review the PNGs, and fix layout issues before delivery.
  6. Run slides_test.py for overflow checks when slide edges are tight or the deck is dense.
  7. Deliver the .pptx, the authoring .js, and any generated assets that are required to rebuild the deck.

Authoring Rules

  • Set theme fonts explicitly. Do not rely on PowerPoint defaults if typography matters.
  • Use autoFontSize, calcTextBox, and related helpers to size text boxes; do not use PptxGenJS fit or autoFit.
  • Use bullet options, not literal • characters.
  • Use imageSizingCrop or imageSizingContain instead of PptxGenJS built-in image sizing.
  • Use latexToSvgDataUri() for equations and codeToRuns() for syntax-highlighted code blocks.
  • Prefer native PowerPoint charts for simple bar/line/pie/histogram style visuals so reviewers can edit them later.
  • For charts or diagrams that PptxGenJS cannot express well, render SVG externally and place the SVG in the slide.
  • Include both warnIfSlideHasOverlaps(slide, pptx) and warnIfSlideElementsOutOfBounds(slide, pptx) in the submitted JavaScript whenever you generate or substantially edit slides.
  • Fix all unintentional overlap and out-of-bounds warnings before delivering. If an overlap is intentional, leave a short code comment near the relevant element.

Recreate Or Edit Existing Slides

  • Render the source deck or reference PDF first so you can compare slide geometry visually.
  • Match the original aspect ratio before rebuilding layout.
  • Preserve editability where possible: text should stay text, and simple charts should stay native charts.
  • If a reference slide uses raster artwork, use ensure_raster_image.py to generate debug PNGs from vector or odd image formats before placing them.

Validation Commands

Examples below assume you copied the needed scripts into the working directory. If not, invoke the same script paths relative to this skill folder.

bash
# Render slides to PNGs for review
python3 scripts/render_slides.py deck.pptx --output_dir rendered

# Build a montage for quick scanning
python3 scripts/create_montage.py --input_dir rendered --output_file montage.png

# Check for overflow beyond the original slide canvas
python3 scripts/slides_test.py deck.pptx

# Detect missing or substituted fonts
python3 scripts/detect_font.py deck.pptx --json

Load references/pptxgenjs-helpers.md if you need the helper API summary or dependency details.
