Create, edit, and analyze .pptx presentations: convert to/from HTML, extract text, edit OOXML, run deterministic workflows for templating, thumbnails, and batch
The PPTX skill documents a complete, deterministic workflow for creating, modifying, and analyzing PowerPoint (.pptx) files. It covers text extraction, raw OOXML unpacking/packing, html2pptx HTML→PowerPoint conversion, template-based editing, thumbnail generation, and validation. The skill is written as a step‑by‑step operational guide with required commands and tooling.
Use this skill when an agent must: generate new presentations from HTML, edit existing decks at the XML level, extract all slide text for review or content replacement, create thumbnail grids for visual QA, or apply validated replacement text to templates. It's intended for automated pipelines and agents that can run Python/Node tooling and external CLI programs (LibreOffice, poppler, etc.).
Best for agents that can run Python and Node.js tooling in a controlled environment (e.g., CI runners, local dev agents, or Claude Code with appropriate runtimes). Not a lightweight demo — it's an operational skill for production workflows.
Comprehensive PPTX creation/editing/analysis skill covering html2pptx workflow, OOXML editing, template-based creation, and thumbnail generation. SKILL.md is very detailed with step-by-step workflows, code examples, and troubleshooting guidance. No bundled scripts were present so static analysis only. Relies on many external dependencies (pptxgenjs, playwright, sharp, LibreOffice, markitdown) which may limit out-of-box usability. No security concerns beyond requiring SKILL_DIR env var and external tool calls.
Well-structured skill with thorough documentation. Main concern is heavy dependency chain and referenced scripts not being bundled. The skill is essentially a detailed guide rather than an executable skill with scripts. Color palette suggestions and layout tips are a nice touch. Proprietary license noted in frontmatter.
