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 | $0.00056 | $0.00665 |
| Opus 5 | $0.00028 | $0.00332 |
| Sonnet 5 | $0.00011 | $0.00133 |
| Haiku 4.5 | $0.00006 | $0.00067 |
Grade A, and why
pptx-handler 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 4d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPTX Handler
Operate on PowerPoint files (.pptx). The pair is: presentation-builder plans the deck (story, slide-by-slide outline); pptx-handler materializes it into a real .pptx file.
Pick the right approach
- Python with
python-pptx— best for full control: layouts, placeholders, shapes, charts. - Pandoc with reveal.js or pptx output — fastest for markdown-to-deck.
- Node with
pptxgenjs— use if Python isn't available.
Install pip install python-pptx if needed. Tell the user.
Generating from an outline
If the user has an outline (or just gave you talking points), turn each section into one slide. Default rule of thumb:
- Title slide — deck title, presenter, date.
- Content slides — one idea per slide, max 7 lines, max 8 words per line.
- Transition slides — single bold word or phrase, used between major sections.
- Closing slide — call to action, next steps, contact.
If the source is markdown with H1/H2 headings, treat each H2 as a slide.
Editing
Common edits:
- Replace placeholder text — find by exact match, replace, preserve runs.
- Update a chart's data — pull the underlying data table, write back.
- Apply a different template — extract content, regenerate against the new layout.
If the deck has merged cells, animations, or transitions, preserve them. python-pptx keeps most of these by default, but verify.
Charts and tables
For numeric data:
- Pull data from the source (often
xlsx-handleroutput). - Generate the chart via
python-pptx.chartrather than embedding screenshots — keeps the deck editable. - Always add a data label or axis label.
Output format
Save to outputs/<topic>.pptx. Also save the source outline as outputs/<topic>-outline.md so the user can regenerate or edit non-visually.
Common mistakes
- Cramming a slide with text. If it doesn't fit in 7 lines, split into two slides.
- Pasting screenshots of charts instead of native charts (loses editability).
- Mixing fonts or colors that don't match the brand. See
brand-guidelines. - Generating a deck without a clear story arc. Use
presentation-builderfirst to plan.
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.

pptx-handler is a skill published in the GitHub repository bjorn-ingmanson/thefroject-plugins (1 stars, last pushed 1mo ago), licensed MIT. It adds 56 tokens to every session and 665 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
