Description
Build high-quality presentation decks from scratch. Covers the full lifecycle from brainstorming through content writing, visual design, AI image generation,...
Usage Guidance
Key things to consider before installing or running this skill:
- It sends your slide text/prompts to external image-generation services (Ofox / OpenRouter). Do NOT feed it confidential content unless you accept that it will be transmitted to those providers.
- The registry metadata does NOT declare required API keys, but the bundled script expects OFOX_API_KEY or OPENROUTER_API_KEY. The error message in the script incorrectly references IMAGE_API_KEY; this mismatch is a bug and a source of confusion.
- The top description claims 'No external SaaS dependency' which is false given the network calls — treat that claim as incorrect.
- Review scripts/generate_deck.py before use (endpoints, model names, and the logic that builds prompts). Consider running in a sandboxed environment, with test/pool API keys that have strict billing limits.
- If you want to avoid exfiltration of sensitive text, either remove/modify the code that sends full content to remote APIs, sanitize prompts, or run a local image model instead.
- If you proceed, set API keys as separate, least-privilege credentials for image-generation only, and monitor usage/billing and network traffic.
If you want, I can: extract the exact lines that reference env var names and endpoints, suggest a minimal patch to make env var usage and error messages consistent, or produce a checklist to safely test the skill in an isolated environment.
Capability Analysis
Type: OpenClaw Skill
Name: ppt-builder
Version: 1.4.0
The 'ppt-builder' skill bundle provides a comprehensive workflow for generating PowerPoint presentations using AI. It includes a Python script (scripts/generate_deck.py) that performs external network requests to AI image generation APIs (api.ofox.ai and openrouter.ai) and utilizes the local file system to store images and assemble PPTX files. While these capabilities are plausibly required for the stated purpose and no clear evidence of malicious intent or data exfiltration was found, the bundle is classified as suspicious due to the presence of high-risk behaviors such as external network access, environment variable reading (API keys), and instructions for shell command execution in SKILL.md.
Capability Tags
Capability Assessment
Purpose & Capability
The skill's code and instructions match the stated purpose (compose content, produce design prompts, call an image model, and assemble a PPTX). However the SKILL metadata and top-line description include contradictory statements (e.g., 'No external SaaS dependency') while the runtime explicitly calls external services (Ofox / OpenRouter / Nano Banana Pro).
Instruction Scope
Runtime instructions and the included script direct the agent to send slide prompts and full slide content to external image-generation APIs. The SKILL.md and references encourage copying content.md verbatim into prompts (one-word-for-word rule), which means potentially sensitive slide text will be transmitted. The docs also contain some inaccurate guidance (the usage error message suggests exporting IMAGE_API_KEY, but the script looks for OFOX_API_KEY or OPENROUTER_API_KEY).
Install Mechanism
There is no install spec (instruction-only), which minimizes install risk, but a runnable Python script is bundled. The script will create files under scripts/output and makes network calls; users should review the script before running. No remote downloads or obscure install URLs are used.
Credentials
The code requires an API key (it looks for OFOX_API_KEY or OPENROUTER_API_KEY) to function, but the registry metadata lists no required env vars or primary credential. This is a meaningful omission. The skill will transmit user prompts/content to third-party APIs, so missing credential declaration and the false 'no external SaaS' claim are disproportionate and misleading.
Persistence & Privilege
The skill does not request persistent or elevated platform privileges (always:false), does not modify other skills or global config, and does not include install-time persistence mechanisms.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install ppt-builder - After installation, invoke the skill by name or use
/ppt-builder - Provide required inputs per the skill's parameter spec and get structured output
Version History
