Reverse-Engineered AI Skill for Real, Editable PowerPoint Decks

What it does

open-kimi-ppt-skill is an unofficial, reverse-engineered implementation of Kimi’s Slides Skill for AI coding agents. It generates presentation projects in a YAML-driven PPTD format that agents can easily manipulate, then exports them to actual, editable PPTX files with embedded fonts and page transitions. A bundled browser-based editor lets you open local PPTD projects, tweak layouts, and re-export without re-running the agent.

The interesting bit

Instead of asking an agent to wrestle with OOXML coordinates or render whole pages as static images, the project uses a structured intermediate layer—PPTD—that describes themes, layouts, and elements in plain YAML. It also runs a multimodal visual QA pass before export, catching overflow, occlusion, and contrast issues so the agent doesn’t ship a broken deck.

Key highlights

• Unofficial reverse-engineering of Kimi Slides protocol and PPTD format, compatible with any SKILL.md-compliant agent (Codex, Claude Code, Cursor, WorkBuddy, etc.)
• Dual output: a reusable, editable PPTD project directory and a finalized PPTX with embedded fonts and fade transitions
• Built-in browser editor for local visual tweaking and manual PPTX export, with auto-save
• Multimodal visual quality check before export: screenshots are inspected for layout bugs, text overflow, and contrast problems
• Around 30 built-in preset themes that match Kimi’s official design system, applied only when explicitly requested

Caveats

• Because it relies on reverse-engineered frontend resources and protocols, the skill may break if Kimi updates its official implementation
• On Windows, PPTX export requires keeping a resident debug browser process running in the background to work around process-handoff limitations
• Output quality can vary significantly if you don’t specify a style or reference template in your prompt

Verdict

Worth a look if you want AI agents to produce real, human-tweakable PowerPoint decks instead of HTML slides or image dumps. Skip it if you need an officially supported, guaranteed-stable integration with Kimi or Moonshot AI.
