Install and run

Setup complexity: low.

clawhub skill install s1738g48aacbj185gdn342x78d84ctfp:ppt-generator-skill

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# PPT Generator Skill

Generate polished `.pptx` presentations using the LLM configured in OpenClaw.  
No external PPT API required — everything runs locally.

## Phase 0 — Environment Check (First-Time Setup)

**Run once after installing the skill, before anything else.**

```bash
python3 scripts/check_env.py
```

The script checks all required and optional dependencies and prints a clear report:

```
══════════════════════════════════════════════════════
  PPT Generator Skill — Environment Check
══════════════════════════════════════════════════════
  ✅  Python 3.9+      (3.11.4)
  ✅  Node.js          (v20.11.0)
  ✅  npm              (10.2.4)
  ✅  pptxgenjs        (installed)
  ✅  markitdown       (0.4.1)
  ✅  pypdf            (4.2.0)
  ✅  python-pptx      (0.6.23)
  ⚠️   LibreOffice      (not found)
  ⚠️   pdftoppm         (not found)
──────────────────────────────────────────────────────

  ⚠️  OPTIONAL — QA features will be unavailable:

  ▸ LibreOffice  — Optional, needed for QA visual inspection
      $ sudo apt install libreoffice       # Ubuntu/Debian
      $ brew install --cask libreoffice    # macOS

  ▸ pdftoppm  — Optional, needed for QA visual inspection
      $ sudo apt install poppler-utils     # Ubuntu/Debian
      $ brew install poppler               # macOS
══════════════════════════════════════════════════════
```

If required (❌) items are missing, exact platform-specific install commands are shown. Fix all required items before proceeding.

**Auto-install missing Python packages:**
```bash
python3 scripts/check_env.py --fix
```

**Machine-readable output (for CI / automated setup):**
```bash
python3 scripts/check_env.py --json
```

## Phase 1 — Requirements Gathering

**Do not run any scripts yet.** First collect everything needed through a short conversation.

### Fast-path — Skip questions when info is already provided

Before asking questions, check whether the user's first message already contains sufficient information. If **at least two** of the following can be inferred from their message, skip the corresponding question steps and proceed directly to Phase 2:

| Info needed | Example signals | Maps to |
|-------------|-----------------|---------|
| Purpose/topic | "AI 趋势", "年度总结", "产品发布" | `{purpose}`, `{raw_topic}` |
| Content source | Uploaded files, or detailed description | `{uploaded_files}` or `{raw_topic}` |
| Slide count or style | "10 页", "科技风", "简约风" | `{slide_count}`, `{style}` |

**Example:** User says "帮我做一个

## Description:

Generate professional .pptx presentations from topics, uploaded documents, or reference materials, with support for custom PPT templates, local generation, real charts, content chunking, and guided conversation flow.

This skill is ready for commercial/non-commercial use.

## Publisher:

[yuchentsai-design](https://clawhub.ai/user/yuchentsai-design)

### License/Terms of Use:

MIT-0

## Use Case:

Employees, external users, and developers use this skill to turn written topics, uploaded source materials, or an uploaded .pptx template into a generated presentation file. It guides requirements gathering, analyzes content and templates, validates a slide plan, and produces a finished .pptx locally.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Generated presentation plans and rendering steps may expose users to code-execution risk.

Mitigation: Run the skill only in an isolated workspace after validating slide plans and removing the identified JavaScript injection path.

Risk: Skipping validation or accepting loose color values can allow unsafe or malformed presentation inputs.

Mitigation: Keep validation enabled for normal use and enforce strict color and slide-plan validation before generating .pptx files.

Risk: The setup workflow can encourage system-level or global dependency installation.

Mitigation: Use pinned dependencies in a local virtual environment and local npm project; do not run curl-to-sudo commands or global installs on sensitive machines.

## Reference(s):

- [PPT Generator Skill Instructions](artifact/SKILL.md)

## Skill Output:

**Output Type(s):** [text, markdown, code, shell commands, configuration, files]

**Output Format:** [Markdown guidance with shell commands, JSON slide plans, validation reports, and generated .pptx files]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Requires Python 3.9+, Node.js, pptxgenjs, markitdown[pptx], pypdf, and python-pptx; optional QA uses LibreOffice and pdftoppm.]

## Skill Version(s):

4.3.0 (source: server release evidence and artifact metadata)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
