Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.03083 |
| Opus 5 | $0.00024 | $0.01541 |
| Sonnet 5 | $0.00010 | $0.00617 |
| Haiku 4.5 | $0.00005 | $0.00308 |
Grade A, and why
pptx-draft scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 419 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PowerPoint Presentation Drafting Skill
Convert Microsoft PowerPoint presentations (.pptx) to structured markdown for easy editing with LLM assistance, then convert back to PowerPoint format with all formatting, layout, and graphics preserved.
When to Use This Skill
Use this skill when:
- User asks to work on, edit, or draft a PowerPoint presentation
- User wants to convert a .pptx file to a more editable format
- User wants to prepare a final .pptx from a draft markdown
- User mentions: "work on this PowerPoint", "edit this presentation", "draft these slides"
How It Works
Phase 1: Convert to Structured Markdown
Converts a .pptx file into a structured markdown file with special markers that preserve the exact structure of the original presentation, including slide layouts, text boxes, tables, and graphics.
Phase 2: Edit the Draft
You (Claude Code) can now edit the structured markdown file. The structure markers ensure the content maps back perfectly to the PowerPoint template.
Phase 3: Convert Back to PowerPoint
Converts the edited structured markdown back to a .pptx file, using the original as a template to preserve all formatting, layout, and graphics.
Usage
Converting TO Structured Markdown
When user says:
- "Convert [file.pptx] to draft format"
- "Use pptx-draft on [file.pptx]"
- "I want to work on this PowerPoint"
- "Convert presentation.pptx to markdown"
Steps:
- Locate the .pptx file
- Run the converter script:
python3 skills-global/pptx-draft/scripts/pptx_draft_converter.py --to-structured <input.pptx> [output.md] - Inform user:
- Where the draft file was created
- CRITICAL: Remind them to keep the original .pptx file in its current location
- Explain they can now edit the draft
- Note: Empty slides will appear as blank placeholder slides in the markdown structure
Example:
python3 skills-global/pptx-draft/scripts/pptx_draft_converter.py --to-structured ~/presentations/Q1_Review.pptx
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
