kimi-slides

A workflow for creating and editing PowerPoint presentations in PPTX format, the file format used by Microsoft PowerPoint. It uses a simpler YAML-based working format and includes tools for validation, conversion, and rendering presentations as images.

In plain words
What is it for?
Use it to generate or edit PPTX files, convert between PPTX and the intermediate format, validate presentation files, and create screenshots of slides.
Why use it?
It provides a more manageable way to change presentation structure and content than editing the underlying PowerPoint XML directly. Rendering helps inspect how the slides look.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kimi-slides scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Definition

kimi-slides is a ppt-generation skill built by Moonshot AI as a first-party skill. It defines a YAML-format intermediate DSL (.pptd) that further abstracts OOXML, making presentation generation effortless. The DSL can be used to generate and render PPTs, and existing pptx files can also be converted into this DSL for editing.

The pptd format

The .pptd format is a simplified abstraction layer over OOXML that follows basic YAML syntax. This abstraction preserves the core content of OOXML (theme, page layout, element positions and definitions, etc.) while removing complex nesting logic such as Masters; every page is self-contained — what you see is what you get. Read reference/pptd.md for the complete definition of this DSL.

Companion CLI

The skill also ships with a companion CLI tool (pre-installed in the environment) for two-way conversion between pptd and pptx, pptd validation, pptd/pptx screenshot rendering, and more. Read reference/cli.md for the complete CLI usage instructions.

PPT production workflow

step1. Read the context thoroughly

Read all files uploaded by the user, the provided URLs, and the pptd format guide reference/pptd.md to fully understand the user's requirements.

step2. Understand the user's requirements

Understand the user's requirements based on the context:

  1. First determine the purpose of the request
  • Create a PPT: create a new presentation (from scratch, or from an existing pptx template)
  • Edit a PPT: edit the user's uploaded PPT (local modifications, single-page beautification, etc.)
  • Replicate a PPT: replicate a presentation from a non-pptx format (images, PDF, etc.) into pptx format
  1. Then determine the design direction
  • Self-directed design: no preference, or only simple style constraints given; you need to fill in or create the design
  • Design system: the user provides a complete and detailed design scheme covering all color, font, layout, and component specifications
  • Use a template: a template is provided and must be used
  • Style transfer: a style reference source is provided (images, web pages, etc.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kimi-slides is a skill published in the GitHub repository XyrusCode/ai-sync (2 stars, last pushed 2d ago), licensed MIT. It adds 99 tokens to every session and 1,724 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
