Presentation Creator

SurgePix Presentation Creator

Generate a polished PowerPoint (.pptx) file from a prompt and optional outline using the SurgePix API. Use when the user asks to create a PPT, make a slide deck, turn an outline into slides, or generate a presentation from a brief.

What the Skill Does

Workflow

1. Step 0: Check environment (required)

   Before running, verify config:

   node "<skills-dir>/surgepix-setup/scripts/check_env.mjs"

   • Exit 0 → proceed to Step 1
   • Exit 1 → follow surgepix-setup skill to configure .env, then retry

2. Step 1: Gather inputs

   At least one of --prompt or --outline is required.

   • Prompt (optional): text describing the presentation topic, purpose, and key points.
   • Outline (optional): local file path or document URL. Script uploads automatically. Supported formats: doc, docx, pdf, txt, md, html, pptx — max 50MB
   • Slide count (optional, default 10, range 5 - 30): use --n
   • Aspect ratio (optional, default 16:9): 16:9 (widescreen) / 4:3 (standard)
   • Style (optional): layout and typography preset. Choose from: modern / corporate / creative / minimal / tech. Use as a quick shorthand for visual direction; omit if --promptPreset Styles section below for detailed descriptions.
   • Language (optional, default: auto-detect from user's input language): zh / en / ja
   • Session ID (optional): if the user is iterating on a previous result, ask them to provide the sessionID (number type) printed by the last run. If this is a fresh request, omit it — the platform auto-creates a new session.
   • Local outline file → script uploads automatically, then calls API
   • Outline URL → script uses it directly

3. Step 2: Run generate-presentation

   node "<skills-dir>/surgepix-generate-presentation/scripts/generate_presentation.js" \
     [--prompt "<text>"] [--outline "<path-or-url>" ...] \
     [--n <5-30>] [--aspect-ratio <16:9>] [--style <name>] \
     [--language <zh|en|ja>] [--session-id <id>]

   Flag	Description
   --prompt <text>	Text describing the presentation topic, purpose, and key points
   --outline <path-or-url>	Outline document (local path auto-uploaded; repeatable for multiple files)
   --n <5-30>	Number of slides, default 10
   --aspect-ratio <ratio>	Aspect ratio, default 16:9 (e.g. 16:9, 4:3)
   --style <name>	Layout preset: modern / corporate / creative / minimal / tech
   --language <code>	Output language: zh / en / ja
   --session-id <id>	Session ID; pass the sessionId (number type) from a previous run to iterate

   The script always uses asynchronous mode (internal noWait=true) — it submits the task and automatically polls until complete.

4. Step 3: Parse output

   Success (stdout):

   {"ok":true,"taskId":"task_xxx","sessionId":123,"progress":"succeeded","download":"https://...presentation.pptx"}

   Failure (stderr):

   {"ok":false,"error":"..."}

5. Step 4: Present result

   • On success: Show the download URL. Always show sessionId (note: it is a number type, e.g. 123) so the user can pass it in a retry if needed
   • On failure: Report the error field. Common causes:
     • Missing required parameter — neither --prompt nor --outline provided
     • Unsupported outline format — file format not supported
     • Outline file too large — exceeds 50MB
     • --n out of range or invalid --language code
     • Generation failed — internal error; retry or simplify the prompt
   • The result is automatically attached to the session (auto-created or reused). The user can open the platform frontend to see all iterations in one place.
   • If the user is not satisfied and wants to iterate, instruct them to pass --session-id <sessionId> (number type) in the next run — both versions appear in the same session history on the frontend.

Rules

• ALWAYS run check_env.mjs before first use in a session
• Provide at least --prompt or --outline
• --n must be an integer between 5 and 30
• If the user wants to iterate, they pass --session-id 123 in the next run — both versions appear in the same session on the frontend.
• If --session-id is omitted, the platform auto-creates a new session for the run.
• The .pptx download URL is valid for 24 hours; download before it expires.
• Supported outline formats: doc, docx, pdf, txt, md, html, pptx — max 50MB.
• NEVER pass local outline paths to the API — script handles upload internally
• NEVER invent download URLs — only use the download value from the output
• NEVER echo auth tokens in logs or output
