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 | $0.00046 | $0.01612 |
| Opus 5 | $0.00023 | $0.00806 |
| Sonnet 5 | $0.00009 | $0.00322 |
| Haiku 4.5 | $0.00005 | $0.00161 |
Grade A, and why
pptx-author 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 9d 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.
This is a copy
95% identical to pptx-author — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
pptx-author
Produce a .pptx file on disk using python-pptx. Use when you need to deliver a deck as a file artifact, not drive a live PowerPoint session.
Adapted from Anthropic's pptx-author and pitch-deck skills in anthropics/financial-services. The MCP / Office-JS branches of the originals are dropped — this assumes headless Python.
For the broader, already-shipped PowerPoint authoring skill (slides, speaker notes, embeds, media), see the built-in powerpoint skill. This skill is a lighter-weight pattern tuned for model-backed decks (pitch decks, IC memos, earnings notes) where every number must trace to a source workbook.
Output contract
- Write to
./out/<name>.pptx. Create./out/if it does not exist. - Return the relative path in your final message.
Setup
pip install "python-pptx>=0.6"
Core conventions
One idea per slide
Title states the takeaway; body supports it. A slide titled "Q3 Revenue" is weak; "Revenue growth accelerated to 14% Y/Y in Q3" is strong.
Every number traces to the model
If a figure on a slide came from ./out/model.xlsx, footnote the sheet and cell.
Revenue: $1,250M (Source: model.xlsx, Inputs!C3)
Never transcribe numbers from memory or from a summary — open the workbook, read the named range, and bind the deck value to it programmatically when you can.
Use the firm template when one is mounted
If ./templates/firm-template.pptx exists, load it so the deck inherits branded colors, fonts, and master layouts.
from pptx import Presentation
from pathlib import Path
template = Path("./templates/firm-template.pptx")
prs = Presentation(str(template)) if template.exists() else Presentation()
Charts: PNG-from-model beats native pptx charts
When fidelity matters (the model's chart styling must match the deck exactly), render the chart to PNG from the source workbook and embed the image. Native pptx.chart charts are fragile and often don't match firm conventions.
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-author is a skill published in the GitHub repository GGbond-bo/MemOmics-Agent (19 stars, last pushed 6d ago), licensed MIT. It adds 46 tokens to every session and 1,612 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to pptx-author, differing in 2 lines, and is treated as a copy.
