- Runs TypeScript and Python scripts from its folder; calls python3, node and soffice
What it does
The agent routes each task to one of three paths. Reading or analyzing a deck uses `python3 -m markitdown` on the file, editing an existing deck or template follows `references/editing.md`, and creating a deck from scratch follows `references/pptxgenjs.md`. To keep the path short, it reads only the reference that applies, writes one generation script, runs one generation phase and one QA phase, and then publishes. Extra references on pitfalls, design systems, backgrounds, slide types, assets and visual quality are read only when a failure or request calls for them.
New decks should feel like finished presentations rather than documents split across slides, with topic-specific visual direction and varied slide structures. When runtime settings are present they act as constraints: slide count, language, visual density and a style preset, one of auto, executive, product, academic, training, minimal or editorial, each mapped to a theme with its own palette in `design-system.md`. A `validate_pptx.py` script is included, and the work happens in SourceWeft's sandbox.
When your agent uses it
- Building a slide deck from scratch as an editable PPTX file
- Editing an existing presentation or template
- Extracting the text of a PowerPoint file
Example prompts
- “Create a twelve-slide product launch deck with a navy and coral look.”
- “Open the quarterly review deck and replace the title slide text, keeping the template layout.”
- “Extract all the text from the board update presentation so I can summarize it.”
- “Make an academic-style deck explaining how vaccines work.”
Requirements
- PptxGenJS for creating decks
- Python with markitdown for reading decks
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- Read pptxgenjs.md.
- Draft the storyboard in the response as a compact per-slide asset plan: for

What it can do on your machine
Read from SKILL.md and the folder at commit 4c67bf9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (TypeScript and Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3nodesofficepdftoppm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
PowerPoint Deck Generator loads about 3.8k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 65 tokens; SKILL.md has 1,826 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,826 words (~3,780 tokens).
“Create native editable PPTX decks in SourceWeft's sandbox. Keep the default path short: route the task, read only the one reference that applies, write one generation script, run one generation phase, run one QA phase, then publish.”
