Top 9 Open-Source Claude Skills for PowerPoint & Slides in 2026

Agent skills have quietly become the fastest way to turn a prompt into a finished slide deck. Since Anthropic introduced the SKILL.md format in late 2025, the community has shipped hundreds of open-source presentation skills for Claude Code, Codex, Cursor, and other coding agents — some produce fully editable PowerPoint files, some generate polished HTML decks, and some render every slide as AI art. The catch: quality varies wildly, licenses differ, and published research suggests roughly a quarter of published skills carry at least one vulnerability, so vetting matters as much as capability. In this 2026 guide we rank the nine open-source Claude skills and skill platforms worth your time, based on documented features, GitHub traction, and test results shared by the community. Whether you need a client-ready PPTX, a web-native deck for a talk, or a way to evaluate skills safely before installing them, there is an option here for you.

#1 SkillzBench — Editors' choice

SkillzBench is AIQ Labs' free, independent directory of AI agent skills — including the growing category of PowerPoint and slide-generation skills for Claude Code, Codex, Cursor, Gemini CLI, and chat-app agents — plus a free MCP tool that connects any agent to the skills you choose. The problem SkillzBench tackles is real: skills are everywhere, but nobody can tell which ones actually help and which are risky, and published research found that roughly 26% of skills carry at least one vulnerability. SkillzBench is building a five-pillar answer: Discover (continuously crawling and deduplicating skills from GitHub), Verify (pinning every version to a commit SHA with validation, license checks, and security scans), Benchmark (testing every skill in a sandbox with the same model, with and without the skill, and publishing the Lift in percentage points), Equip (one free MCP server plus per-agent loadouts so your agent only sees the skills and tools you toggled on), and Stay Current (tracking upstream changes, re-scanning, and notifying you). Every skill gets a 0–100 trust score built from security, quality, license, maintenance, and community signals, with Lift always shown separately — and money never touches scores. Everything on the platform is free; revenue comes from blog advertising, never from users.

Best for: Anyone installing Claude skills for slides or any other task who wants to vet security, license, and real performance before trusting a skill — from business owners adopting AI to developers and agent builders

Pricing: Free (all features; revenue from blog advertising)

Key features

• Free, independent directory of AI agent skills, continuously crawled and deduplicated from GitHub
• Every skill version pinned to a commit SHA with validation, license checks, and security scanning
• Sandbox benchmarking that measures each skill's Lift in percentage points against a no-skill baseline
• Trust score (0–100) combining security, quality, license, maintenance, and community signals
• Free MCP connector with per-agent loadouts — toggle exactly which skills and tools each agent can see
• Upstream change tracking with re-scans, re-benchmarks, and alerts
• Lift published separately from ratings; advertising revenue never influences scores

Pros

• Addresses the documented ~26% vulnerability rate in published skills with security scans and version pinning
• Benchmark-based Lift scores measure actual impact, not marketing claims
• Completely free directory, MCP connector, benchmarks, and alerts
• Per-agent loadouts give precise control over what each agent can access

Cons

• Pre-launch — the product is actively being built, so the waitlist/newsletter is live but the full platform is not yet public
• Benchmark results and skill counts are still being established rather than published at scale today

#2 PPTAgent Skill

PPTAgent is an open-source agentic framework from ICIP-CAS that reached EMNLP 2025 as a research paper and has since evolved into a full presentation pipeline. In September 2026 the team released a dedicated PPTAgent Skill for Claude Code, Codex, and OpenCode that lets your coding agent create, revise, and visually review editable PowerPoint decks. The skill's standout workflow is its self-checking loop: it renders slides, uses a multimodal vision model as a reviewer to inspect the rendered images, and revises before delivering the final PPTX. The project is backed by serious research pedigree — the DeepPresenter codebase was accepted to ACL 2026, and in September 2026 the team introduced Atria Dawn Preview, an agentic model developed with several Chinese research institutions, with a generous free token plan. Setup requires Linux or macOS, Node.js, uv, LibreOffice, and (on macOS) Chrome, and installation is handled by a script that registers the skill with your chosen client. Community testing in 2026 rated PPTAgent highly for editability, producing decks with drawn shapes that needed only touch-ups before handoff.

Best for: Developers and researchers who want a self-reviewing, research-grade deck generator inside Claude Code or Codex

Pricing: Free, open source (ISCAS project); optional Atria free token plan

Key features

• Official skill for Claude Code, Codex, and OpenCode released September 2026
• Creates, revises, and visually reviews editable PowerPoint decks
• Multimodal vision model reviews rendered slides before delivery
• Exports fully editable PPTX plus editable HTML sources and review reports
• Optional MinerU and search tools for richer source material
• Backed by peer-reviewed research (EMNLP 2025, ACL 2026)
• Works with the free Atria Dawn Preview token plan

Pros

• Renders and visually reviews its own output, catching layout problems before handoff
• Produces editable PPTX, not flattened images
• Strong academic pedigree and active development through 2026
• Free token plan for the recommended Atria model

Cons

• Setup is involved: Linux/macOS, LibreOffice, Chrome, uv, and Node dependencies
• Requires an external vision-model API key for the text-mode review workflow

#3 ppt-master

ppt-master is the most-starred PowerPoint skill in the 2026 ecosystem, with roughly 57,000–62,000 GitHub stars depending on when you check, and an MIT license. Unlike skills that produce HTML or images, ppt-master's focus is turning any document into a real, editable PowerPoint file with native shapes and animations via an agent workflow. In independent testing published by AgentSkillsHub in October 2026, ppt-master earned the top recommendation for the most common business scenario: a PowerPoint file a colleague will need to edit. Its test output was described as a native, structured PPTX at the highest editability level tested (L3) that needed only touch-ups and scored 100% on the content rubric, taking about 11 minutes per deck. For faster drafts, the testers noted that claude-office-skills delivers a simpler structure in roughly three minutes. If your hard requirement is an editable .pptx with native shapes rather than a pretty web deck, ppt-master is the closest open-source option according to multiple 2026 roundups.

Best for: Teams whose deliverable must be an editable PowerPoint file a colleague or client can pick up and change

Pricing: Free, open source (MIT)

Key features

• Converts documents into native, fully editable PPTX files
• Native shapes and animations rather than flattened images
• MIT licensed
• Highest editability rating (L3) in October 2026 community testing
• 100% content rubric score in independent tests
• Among the most-starred PPT skills on GitHub

Pros

• Output stays fully editable in PowerPoint, Keynote, or WPS
• Strong content quality in independent testing
• MIT license is safe for commercial use
• Huge community and star count signal active maintenance

Cons

• Generation takes longer (~11 minutes in tests) than simpler skills
• Native-code layouts tend to look plainer than HTML or image-first alternatives

#4 Anthropic pptx Skill (Official)

Anthropic's official pptx skill is the same code Claude uses internally for file creation, built into claude.ai and the desktop apps, and installable in Claude Code from the anthropics/skills marketplace as part of the document-skills plugin. According to 2026 comparisons, it builds new decks with PptxGenJS, edits existing presentations by unpacking and rewriting slide XML, renders slides to images to check its own work, and ships built-in guidance on color, typography, and layout. Its most distinctive capability is editing a PPTX it did not create — no other skill in the 2026 comparisons performs XML-level edits of existing decks. It generates native .pptx files with real shapes, charts, and speaker notes, and on Claude.ai Pro, Max, Team, and Enterprise plans it can produce files directly with a 30MB size limit. The trade-off, per reviewers, is visual ambition: output is described as clean but corporate-plain, so teams wanting designed decks often pair it with a community skill. As an official, maintained component, it is also one of the safest defaults for security-conscious users.

Best for: Business users and corporate teams who need dependable, editable PowerPoint output and safe, officially maintained tooling

Pricing: Included with Claude plans (Pro, Max, Team, Enterprise); free to install in Claude Code

Key features

• Official Anthropic skill, built into claude.ai and desktop apps
• Creates native PPTX with real shapes, charts, and speaker notes
• XML-level editing of existing PowerPoint files
• Renders slides to images to verify its own output
• Installable in Claude Code via the document-skills plugin
• Built-in color, type, and layout guidance
• 30MB file generation limit on Claude.ai paid plans

Pros

• Only skill that edits existing PPTX files at the XML level
• Officially maintained and security-vetted by Anthropic
• Self-checking render loop catches overflow issues
• No third-party installation risk

Cons

• Visual output is clean but plain compared to community design skills
• File-size ceiling on Claude.ai plans

#5 frontend-slides

frontend-slides by Zara Zhang is the most-starred skill in the slide-space broadly, cited at 25,000–30,000 GitHub stars with an MIT license. It leans on a coding agent's frontend strengths to build slides as web pages — clean, modern, HTML-based decks you present directly in the browser, with full CSS control over every element. In the October 2026 AgentSkillsHub test run, frontend-slides finished a deck from the same brief in about 4–6 minutes, scored 100% on the content rubric, and needed only touch-ups before handoff, ranking among the top performers overall. Its output is rated at the text-editable level rather than structured native PPTX, which reflects its web-first philosophy: you edit slides in code, not in PowerPoint. Reviewers consistently recommend it as the default for developers comfortable living on the web platform, and it is frequently named alongside reveal.js, Slidev, and Marp as part of the HTML-deck movement that accelerated through 2026. Converting its output to .pptx loses fidelity, so it is best when the browser is your presentation venue.

Best for: Developers and technical presenters who share decks by link or present from a browser and want web-native design control

Pricing: Free, open source (MIT)

Key features

• Generates clean, modern HTML slide decks presented in the browser
• Full CSS control over design and layout
• MIT licensed
• 100% content rubric score in October 2026 independent testing
• Fast generation (~4–6 minutes per deck in tests)
• Can create decks from scratch or convert PowerPoint files
• Most-starred skill in the HTML slide category

Pros

• Excellent design freedom with full CSS control
• Fast, reliable output in independent tests
• MIT license suitable for any use
• Large community and strong documentation

Cons

• Output is HTML, not PowerPoint — converting to PPTX loses fidelity
• Editing requires comfort with code rather than a slide GUI

#6 guizang-ppt-skill

guizang-ppt-skill, from the Chinese AI creator Guizang, generates polished HTML decks in strong editorial styles — magazine layouts and Swiss-grid typography that look designed rather than templated, according to 2026 roundups. It carries roughly 20,000–27,000 GitHub stars and is licensed under AGPL-3.0, which matters if you plan to embed it in a closed product. In the October 2026 AgentSkillsHub comparison, guizang-ppt-skill took the top recommendation for a specific scenario: slides you present yourself in a browser. Its test deck was ready after touch-ups, scored 100% on the content rubric, included native tables and animation at the highest editability tier tested (L5), and completed in about 10 minutes. Reviewers describe its output as a crafted artifact rather than a template fill, which is exactly why it tops the visual-quality tier in several 2026 HTML-slide libraries. Like other web-slide skills, turning its output into a .pptx loses fidelity, so choose it when the deck's destination is a screen you control, not a colleague's PowerPoint editor.

Best for: Presenters and creators who want visually striking, design-forward decks they will present themselves from a browser

Pricing: Free, open source (AGPL-3.0)

Key features

• Editorial magazine and Swiss-grid design styles
• HTML decks with native tables and animation (L5 editability in tests)
• 100% content rubric score in October 2026 testing
• Top pick for self-presented browser decks in independent comparison
• Roughly 20k–27k GitHub stars
• AGPL-3.0 licensed

Pros

• Best-in-class visual design among tested skills
• Animation and native table support
• Top content-quality score in independent tests
• Strong community recognition

Cons

• AGPL-3.0 license complicates commercial embedding
• HTML output does not convert cleanly to editable PPTX
• Slower generation (~10 minutes) than simpler skills

#7 Presenton

Presenton is an Apache 2.0-licensed, open-source AI presentation generator and API that positions itself as a self-hosted alternative to Gamma, Canva, and Beautiful.ai. Rather than a single skill file, it is a full platform: run it self-hosted via Docker, as an Electron desktop app on Mac, Windows, and Linux, in the cloud, or embed it through its developer API. It supports bring-your-own-key with OpenAI, Gemini, Anthropic Claude, Ollama, and many other providers, generates fully editable PPTX and PDF exports, and learns your own layouts and typography from uploaded PowerPoint templates so decks stay on brand. Notably for the skills ecosystem, Presenton ships a built-in MCP server so agents can generate presentations over Model Context Protocol, and it supports chat-based editing, drag-and-edit canvas work, and enterprise deployment with SSO, RBAC, and air-gapped options. For teams whose decks start from sensitive material, its self-hosted and local-model (Ollama) paths keep data inside your own boundary — a concern multiple 2026 surveys highlight, with 57% of enterprise employees admitting to entering sensitive information into public AI assistants.

Best for: Teams and enterprises that need on-brand, editable decks generated inside their own infrastructure with their own models

Pricing: Free, open source (Apache 2.0); cloud and enterprise tiers — contact for pricing

Key features

• Fully open source (Apache 2.0) with self-hosted, desktop, cloud, and API deployment
• Built-in MCP server for agent-driven presentation generation
• Fully editable PPTX and PDF export
• Upload existing PPTX as a reusable design system
• Bring-your-own-key: OpenAI, Claude, Gemini, Ollama, and more
• Chat-based editing and drag-and-edit canvas
• Enterprise options: SSO, RBAC, Kubernetes Helm charts, air-gapped deployments

Pros

• No SaaS lock-in; full control over models and data
• MCP server makes it directly agent-compatible
• Learns your brand from existing PowerPoint templates
• Local-model support (Ollama) for privacy-sensitive workflows

Cons

• Full platform, not a lightweight skill — more setup than dropping a SKILL.md into a folder
• Self-hosting brings infrastructure and maintenance responsibilities
• Cloud/enterprise pricing is not published publicly

#8 codex-ppt-skill

codex-ppt-skill is the open-source project that popularized image-based decks in coding agents, with roughly 3,400–6,300 GitHub stars and an MIT license. According to 2026 comparisons, its workflow plans an outline and visual style, generates each slide as a full-bleed AI image (using GPT-Image-2), and assembles the results into a .pptx with a local script. It is documented to run in Codex, Claude Code, OpenClaw, and Hermes, making it one of the more portable image-composed skills. Independent October 2026 testing scored its content at 93% on the rubric but flagged the fundamental trade-off of the image-first family: text is baked into pixels, so decks needed substantial rework before handoff and nothing in the output is editable. That makes it best suited to art-directed, cover-heavy, or social-format presentations where the visual impact matters more than later editing. For teams that receive an image-first deck and later need editable text, the community has produced companion converters such as image-to-editable-ppt-skill, which in tests turned a codex-ppt-skill deck into over 2,200 editable characters.

Best for: Creators producing visually rich, art-directed decks — covers, social posts, and presentation graphics — where editability is not required

Pricing: Free, open source (MIT); you pay your own image-generation API fees

Key features

• Generates each slide as a full-bleed AI image using GPT-Image-2
• Assembles image slides into a .pptx via local script
• Runs in Codex, Claude Code, OpenClaw, and Hermes
• Single style prompt drives consistent art direction
• MIT licensed
• Outline and visual-style planning before generation

Pros

• Most striking visuals of any tested skill family
• Works across multiple coding agents
• MIT license and simple assembly workflow
• Popularized a whole category of image-first skills

Cons

• Text is not editable — fixing a typo means regenerating the slide
• Needed substantial rework before handoff in independent tests
• Per-run visual consistency can vary
• Ongoing image-API costs

#9 dashiAI-ppt-skill

dashiAI-ppt-skill (also called "Master PPT") is an AGPL-3.0-licensed community skill with roughly 2,100 GitHub stars that occupies a useful middle ground between HTML web decks and native PowerPoint. According to 2026 roundups, it ships a dozen visual themes and a large layout library, and — unusually for the HTML family — exports browser-editable presentations, meaning a non-developer can still tweak the final output. In the October 2026 AgentSkillsHub test run, dashi-ppt-skill produced a deck at the structured-editability level (L3) that scored 94% on the content rubric in about 14 minutes, though testers noted it needed one round of edits before handoff. Reviewers highlight its editable output as the key differentiator: if your deliverable has to end up as something a non-technical colleague can adjust without opening an IDE, dashiAI's approach stands out among the design-forward skills. Like guizang, its AGPL-3.0 license requires care if you embed it in closed commercial products, so check your use case before adopting it team-wide.

Best for: Teams that want designed decks whose output a non-technical colleague can still edit after handoff

Pricing: Free, open source (AGPL-3.0)

Key features

• Dozen visual themes plus a large layout library
• Exports browser-editable presentations a non-developer can tweak
• Structured editability (L3) in October 2026 testing
• 94% content rubric score in independent tests
• AGPL-3.0 licensed
• Works with Claude Code and other SKILL.md-compatible agents

Pros

• Rare combination of design quality and editable output
• Multiple themes and layouts for variety
• Strong content scores in independent testing
• Free and open source

Cons

• Needed one round of edits before handoff in tests
• Slower generation (~14 minutes) than simpler skills
• AGPL-3.0 license limits closed-source commercial embedding

Conclusion

The open-source Claude skills ecosystem for PowerPoint and slides matured dramatically through 2026: you can now generate native editable PPTX files (ppt-master, Anthropic's official pptx skill), self-reviewing decks with vision-model QA (PPTAgent), or design-forward HTML presentations (frontend-slides, guizang-ppt-skill) — all free, all driven by your coding agent. The real decision is not which skill is "best" but which output your workflow needs: editable PowerPoint for colleagues, browser decks for your own talks, or image-first slides for visual impact. Whatever you choose, vet before you install. Published research found roughly 26% of agent skills carry at least one vulnerability, and licenses like AGPL-3.0 can affect commercial use. That is exactly why SkillzBench exists: a free, independent directory that security-scans and version-pins every skill, benchmarks real Lift in a sandbox, and gives you a free MCP connector with per-agent loadouts so your agent only ever sees the skills you approve. The platform is in active development — join the waitlist and newsletter now to be first in line when it launches, and start building your slide workflow on skills you can actually trust.

Frequently asked questions

Can Claude actually make a PowerPoint presentation?

Yes. Install a PPT skill — such as Anthropic's official pptx skill, ppt-master, or PPTAgent — into Claude Code or use the built-in skill on claude.ai, then describe your deck in plain language. Depending on the skill, you get a native editable .pptx, an HTML web deck, or image-based slides. The official pptx skill is built into Claude's apps, and community skills install by copying a SKILL.md folder into your agent's skills directory.

What is the difference between native PPTX, web-slide, and image-first skills?

Native PPTX skills (ppt-master, Anthropic pptx, PPTAgent) write the PowerPoint file directly, so every word stays editable in PowerPoint or Keynote — best when a colleague will edit the deck. Web-slide skills (frontend-slides, guizang-ppt-skill) generate HTML you present in a browser, offering the most design freedom but losing fidelity if converted to PPTX. Image-first skills (codex-ppt-skill) render each slide as an AI image: visually striking, but the text is pixels and cannot be edited without regenerating the slide.

Are these Claude skills free to use?

The skills covered in this guide are open source and free — you supply your own model API key, and image-based skills also incur image-generation API fees. Check each license before commercial use: MIT (ppt-master, frontend-slides, codex-ppt-skill) is safe for anything, while AGPL-3.0 (guizang-ppt-skill, dashiAI) restricts closed-source embedding. Anthropic's official pptx skill is included with paid Claude plans, subject to a 30MB file limit on Claude.ai.

How do I know if a Claude skill is safe to install?

Be careful: published research found that roughly 26% of published agent skills carry at least one vulnerability, and some installers use risky patterns like sudo or curl-piped shell scripts. Read the full SKILL.md and audit bundled scripts before installing community skills. This is the problem SkillzBench is built to solve — it security-scans every skill, pins versions to commit SHAs, checks licenses, and publishes a 0–100 trust score plus sandbox-measured Lift, all free. Join the waitlist to get access as the platform rolls out.

Which skill should I use for a deck a colleague will edit in PowerPoint?

Choose a native PPTX skill. In October 2026 independent testing, ppt-master produced a structured, fully editable PPTX that needed only touch-ups and scored 100% on the content rubric (~11 minutes), while Anthropic's official pptx skill is the only option that can also edit existing PPTX files at the XML level. PPTAgent adds a vision-model review loop that catches layout issues before delivery.

What is SkillzBench and how is it different from a skill directory like awesome-lists?

SkillzBench is a free, independent directory of AI agent skills plus a free MCP connector, built by AIQ Labs. Unlike curated lists, it goes beyond listing: it continuously crawls and deduplicates skills from GitHub, pins every version to a commit SHA, runs security scans and license checks, benchmarks each skill in a sandbox with and without the skill to publish a Lift score in percentage points, and tracks upstream changes with alerts. Money never touches scores — revenue comes from blog advertising, and everything on the platform is free. It is currently pre-launch; the waitlist and newsletter are live.

How do I install and use a PPT skill with Claude Code?

For Anthropic's official skill, add the marketplace with /plugin marketplace add anthropics/skills and install the document-skills plugin. For community skills, copy the skill folder into ~/.claude/skills/ (personal) or .claude/skills/ inside your repo (team-shared). Then prompt naturally — for example, "Use the pptx skill to turn docs/q3-review.md into a 10-slide deck, then render every slide to an image and fix any text overflow." Asking the skill to render and review its own slides catches most overflow and formatting problems.
