What it does

PPTX is an agent skill from happycapy-ai/Happycapy-skills. Create polished PowerPoint (.pptx) presentations directly from a topic or content description. Uses HTML as an invisible internal design intermediate — the HTML is never shown to the user. The final and only deliverable is a .pptx file saved to outputs/. Use this skill whenever the user asks to: make a PPT / PowerPoint / 幻灯片 / 演示文稿, generate slides about a topic, or turn any content into a presentation deck. Supports Chinese and English. Always outputs .pptx, never HTML.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `README.md` and `scripts/pptx_builder.py`).

It sits in Documents & Office, covering PowerPoint presentations and Slides and decks. It works with Microsoft PowerPoint. The repository describes itself as: A curated collection of high-quality Claude Code skills to enhance your development workflow. The licence is MIT.

When your agent uses it

Requirements

Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Design the HTML Draft (Internal only)
Extract Theme & Build PPTX
Deliver

What it can do on your machine

Read from SKILL.md and the folder at commit 9ff72fe. 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 1 file in scripts/ (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

PPTX loads about 1.5k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~120
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

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); the scripts in this folder are not scanned.

SKILL.md

The full file from happycapy-ai/Happycapy-skills at commit 9ff72fe, republished under its MIT licence (© happycapy-ai). 328 words, ~1,473 tokens.

name: pptx
description: Create polished PowerPoint (.pptx) presentations directly from a topic or content description. Uses HTML as an invisible internal design intermediate — the HTML is never shown to the user. The final and only deliverable is a .pptx file saved to outputs/. Use this skill whenever the user asks to: make a PPT / PowerPoint / 幻灯片 / 演示文稿, generate slides about a topic, or turn any content into a presentation deck. Supports Chinese and English. Always outputs .pptx, never HTML.

PPTX Skill

Generate a polished PPTX in three phases. The HTML draft is purely internal — never reference or expose it to the user.

Phase 1 — Design the HTML Draft (Internal only)

Write a single self-contained HTML presentation to tmp/<name>-draft.html.

Design principles:

Choose a bold, distinctive aesthetic (dark editorial, pastel geometry, neon cyber, etc.)
Define a CSS :root {} block with named color variables: --bg, --bg1, --bg2, --text, --muted, --accent, --dim, etc. Use hex values only.
Each <section class="slide" id="sN"> is one slide. Viewport-locked 100vh, scroll-snap, no overflow.
Use Google Fonts — avoid Inter/Roboto. Good choices: Fraunces, DM Sans, Syne, Outfit, Cormorant.
Staggered reveal animations are fine for the HTML but irrelevant to PPTX.

This HTML serves one purpose: capture color theme + slide structure + text content + layout intent before building the PPTX.

Phase 2 — Extract Theme & Build PPTX

Read tmp/<name>-draft.html
Extract the CSS color theme using extract_theme_from_html() from scripts/pptx_builder.py
Write a one-off build script to tmp/<name>-build.py:
- Import Builder from scripts/pptx_builder.py (add skills scripts dir to sys.path)
- Instantiate Builder(theme) with the extracted colors
- Recreate each HTML slide using Builder primitives
- Save to outputs/<name>.pptx
Run: python3 tmp/<name>-build.py

sys.path setup (always required)

python

import sys
sys.path.insert(0, "/home/node/.claude/skills/pptx/scripts")
from pptx_builder import Builder, extract_theme_from_html
from pptx.util import Inches, Pt
from pptx.enum.text import PP_ALIGN

html = open("tmp/deck-draft.html").read()
theme = extract_theme_from_html(html)   # {"bg":"#0b0b0b", "accent":"#c9a84c", ...}
b = Builder(theme)

Builder API

python

slide = b.new_slide()              # blank slide with bg fill

# Shapes
b.rect(slide, x, y, w, h, fill="bg1", border="dim")
b.hline(slide, x, y, w, color="accent")
b.oval(slide, x, y, w, h, fill="bg1")
b.card(slide, x, y, w, h)         # shortcut for bg1 card with border

# Text
b.txt(slide, "text", x, y, w, h,
      size=14, bold=False, italic=False,
      color="text",               # theme key or "#hexcode"
      align=PP_ALIGN.LEFT)

b.multicolor_txt(slide, [         # mixed colors in one line
    {"text": "White ",  "size": 52, "bold": True, "color": "text"},
    {"text": "Gold",    "size": 52, "bold": True, "italic": True, "color": "accent"},
], x, y, w, h, align=PP_ALIGN.LEFT)

# Helpers
b.eyebrow(slide, "LABEL", x, y)   # small gold uppercase label
b.logo(slide, "Name", x, y)
b.slide_number(slide, n=1, total=9)

# Grid of cards
b.grid_cards(slide, items, x0, y0, card_w, card_h, gap,
             cols=4, draw_fn=fn)  # fn(slide, b, item, cx, cy, cw, ch)

b.save("outputs/deck.pptx")

Color keys: any key from the theme dict ("bg", "bg1", "text", "muted", "accent", "dim", etc.) or a raw "#rrggbb" string.

Phase 3 — Deliver

Attach outputs/<name>.pptx in the <attachments> block
Do NOT mention the HTML draft or tmp files
The user should only see the PPTX as output

PPTX Layout Conventions

Slide size: 13.33 × 7.5 in (16:9). Set automatically by Builder.

Slide type	Approach
Cover	Oversized multicolor title (Pt 100–130), gold rule, tagline below
Content	Eyebrow + heading + description + card grid
Split	Left column: text + bullets. Right column: visual card panel
Quote	Centered quote Pt 44–60, accent line above
CTA	Centered heading + description + gold button rect + stats row

Limits per slide: 1 heading, max 6 bullets, max 6 cards in a grid.

Common Patterns

Cover with giant title:

python

s = b.new_slide()
b.multicolor_txt(s, [
    {"text": "My ",  "size": 120, "bold": True, "color": "text"},
    {"text": "Brand", "size": 120, "bold": True, "color": "accent"},
], Inches(0.8), Inches(1.0), Inches(12), Inches(3.5))
b.hline(s, Inches(0.8), Inches(4.8), Inches(2.5))
b.txt(s, "Tagline text here", Inches(0.8), Inches(5.1), Inches(7), Inches(0.9),
      size=16, color="muted")
b.slide_number(s, 1, 9)

Card grid:

python

items = [("📝", "Title", "Description"), ...]

def draw(slide, b, item, cx, cy, cw, ch):
    ico, lbl, desc = item
    b.txt(slide, ico,  cx+Inches(0.2), cy+Inches(0.2), cw, Inches(0.5), size=20)
    b.txt(slide, lbl,  cx+Inches(0.2), cy+Inches(0.8),  cw-Inches(0.4), Inches(0.45), size=12, bold=True)
    b.txt(slide, desc, cx+Inches(0.2), cy+Inches(1.3),  cw-Inches(0.4), Inches(0.65), size=10, color="muted")

b.grid_cards(s, items, Inches(0.8), Inches(3.4), Inches(2.9), Inches(2.1), Inches(0.22), cols=4, draw_fn=draw)

Bullet list with gold dots:

python

bullets = ["Item one", "Item two", "Item three"]
for i, text in enumerate(bullets):
    fy = Inches(3.5) + i * Inches(0.55)
    b.oval(s, Inches(0.8), fy + Inches(0.15), Inches(0.12), Inches(0.12), fill="accent")
    b.txt(s, text, Inches(1.1), fy, Inches(5.0), Inches(0.45), size=13)

Gold CTA button:

python

b.rect(s, Inches(4.7), Inches(5.1), Inches(3.9), Inches(0.6), fill="accent", border=None)
b.txt(s, "Get Started  →", Inches(4.7), Inches(5.13), Inches(3.9), Inches(0.55),
      size=13, bold=True, color="bg", align=PP_ALIGN.CENTER)

Questions about PPTX

What does PPTX do?

Create polished PowerPoint (.pptx) presentations directly from a topic or content description. PPTX is an agent skill from happycapy-ai/Happycapy-skills.pptx) presentations directly from a topic or content description.

When should I use PPTX?

PPTX fits situations like: the user asks to: make a PPT / PowerPoint / 幻灯片 / 演示文稿; generate slides about a topic; turn any content into a presentation deck.

How do I install PPTX in Claude Code?

Run `npx skills add happycapy-ai/Happycapy-skills --skill pptx -a claude-code`. Or copy the skill folder (skills/pptx in happycapy-ai/Happycapy-skills) into .claude/skills/pptx in your project. Claude Code loads it when a task matches its description.

How do I install PPTX in Codex?

Run `npx skills add happycapy-ai/Happycapy-skills --skill pptx -a codex`. Or copy the skill folder (skills/pptx in happycapy-ai/Happycapy-skills) into .agents/skills/pptx in your project. Codex loads it when a task matches its description.

Can I use PPTX in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add happycapy-ai/Happycapy-skills --skill pptx -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pptx, .gemini/skills/pptx, .github/skills/pptx and .opencode/skills/pptx in your project.

What does PPTX need to run?

Going by SKILL.md and its folder, PPTX needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.

Does PPTX access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is PPTX safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does PPTX use?

PPTX is published under the MIT licence (from the LICENSE file in the skill folder). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does PPTX use?

About 1.5k tokens (SKILL.md is roughly 5.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to PPTX?

Skills that share tags, products or a category with PPTX: Image To Editable Ppt (ningzimu/image-to-editable-ppt-skill, 2.8k stars), Slides (fcakyon/claude-codex-settings, 1.2k stars), Ppt Image First (NyxTides/ppt-image-first, 1.2k stars) and Gpt Image2 Ppt (JuneYaooo/gpt-image2-ppt-skills, 1.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains PPTX?

happycapy-ai (a GitHub user) maintains it in happycapy-ai/Happycapy-skills, which has 137 GitHub stars. The repository holds 28 skills in this directory. The repository was last updated on September 3, 2026.
