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 | $0.00091 | $0.02185 |
| Opus 5 | $0.00046 | $0.01092 |
| Sonnet 5 | $0.00018 | $0.00437 |
| Haiku 4.5 | $0.00009 | $0.00218 |
Grade A, and why
talksmith:pptx-extract 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 3d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
talksmith:pptx-extract — Rebuild the presentation Markdown from a deck
Talksmith's forward pipeline is one-directional: draft.md → final.md → talks/<Talk>/output/final.pptx. When a presenter opens that deck in Keynote/PowerPoint and edits text or swaps/adds images, those edits live only in the .pptx. This skill reads the edited deck back into the canonical Markdown shape so the changes can be diffed (talksmith:pptx-diff) and merged into draft.md (talksmith:pptx-merge).
| The caller does | This skill does |
|---|---|
Points at the edited .pptx + the active Talk + the render style |
Parses the deck, classifies slides, de-dups images, writes finalpptx.md + inventory |
Refines the mechanical draft (resolves <!-- reconstruct: ... --> markers) |
Emits a conservative first pass; never invents Thesis/Sources |
Reading a .pptx needs only python-pptx (a pip install), not the native pptx skill — so, unlike md-to-deck, which is Cowork-only because authoring a deck needs the native pptx skill, this skill is fully CLI-safe.
When to use
- A presenter edited the generated deck externally and wants those edits pulled back into the Talk source.
- Any time you need a Markdown view of what a
.pptxactually contains, indraft.mdshape.
Run this first in the reverse pipeline, then talksmith:pptx-diff, then talksmith:pptx-merge.
Inputs
| Input | Required? | Notes |
|---|---|---|
pptx |
yes | Path to the edited deck, e.g. talks/<Talk>/output/final.pptx. |
--talk |
yes | Talk root, e.g. talks/<Talk>. Its images/ folder is the reference set for image de-duplication. |
--style |
yes | strict or free-form — no default. Cover fingerprint, section-pill fill, and agenda dot colors are style-specific. strict supports full cover/agenda/divider classification; free-form only reliably identifies the cover (content grouping is flat — a warning is emitted). |
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.

talksmith:pptx-extract is a skill published in the GitHub repository veigap/talksmith (10 stars, last pushed 5d ago), licensed MIT. It adds 91 tokens to every session and 2,185 once invoked, about $0.0005 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.
