2slides Presentation Generation
Detailed Guide
Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
When to Use This Skill
Use when the user asks to "create a presentation", "make slides", or "generate a deck" from text or an outline.
Use when the user wants slides that match the style of a reference image ("create slides like this image").
Use when the user wants custom-designed PDF slides without a reference image.
Use when the user uploads a document and asks to "create slides from this document".
Use when the user wants to add AI voice narration to generated slides, or export slides as PNG images and narration as WAV audio.
Use when the user asks "what themes are available?" or wants to browse/select a theme.
Security & Safety Notes
Credentials: This skill reads the API key from the SLIDES_2SLIDES_API_KEY environment variable. Never hard-code the key in commands, commit it, or echo it back to the user. The scripts send it as a bearer/apikey value to https://2slides.com over HTTPS only.
Network + paid mutations: Every generation call makes an outbound network request to the 2slides API and spends the user's credits (10–210 credits/page depending on mode). Treat generation, reference-image, custom-PDF, and narration calls as billable actions — confirm intent before generating large or high-resolution (4K) decks, and surface the expected page count/cost when it is non-trivial.
No destructive local actions: The scripts only read content/files the user points to and write generated output (e.g. a downloaded ZIP) to the path the user specifies. They do not modify or delete unrelated files.
Input handling: Reference-image and document inputs are sent to the 2slides service for processing. Do not submit confidential material the user has not authorized for third-party processing.
Download URLs expire in 1 hour — fetch artifacts promptly and do not treat the URLs as durable storage.
Limitations
Requires a valid 2slides account, API key, and sufficient credits; this skill does not provision or pay for credits.
Results are AI-generated drafts intended as a starting point, not a final, fact-checked deliverable — review content before use.
This skill does not replace environment-specific validation or expert review. Stop and ask for clarification if the API key, required inputs, or intended cost/scope are missing.
Rate limits apply (Fast PPT 10/min, Nano Banana 6/min); poll async jobs every 20–30s rather than tight-looping.
Find and fix WCAG 2.2 accessibility issues. Two modes — report (sweep a codebase or page, produce a prioritized written report, no edits) and fix (audit→edit→verify loop on a target). Prefers direct-CDP live-DOM auditing; falls back to a browser-MCP composition or HTML-string audits.
