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 | $0.00039 | $0.00572 |
| Opus 5 | $0.00019 | $0.00286 |
| Sonnet 5 | $0.00008 | $0.00114 |
| Haiku 4.5 | $0.00004 | $0.00057 |
Grade A, and why
pptx-reference-deck-analysis 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPTX Reference Deck Analysis
Inspect a reference deck as design evidence. This skill never copies, clones, or mutates a source deck.
Contract
Implement required extraction on demand with a small task-local python-pptx script. Capture only the information required for the new deck:
- compact prompt context: slide count and size, text summaries, shape counts, styles, brand signals, template use, and layout rhythm;
- full extraction:
summary, slides, and read-onlylayout_treeevidence; - folder diagnostics: one result per deck plus a manifest;
- style-master analysis: colors, fonts, size distribution, master/layout use, and flow patterns;
- derived template catalog: zero-based source indices, layout roles, usable regions, placeholders, visual structures, and constraints.
Rules
- Keep the source deck read-only and independently author every target-slide coordinate.
- Use the bundled OOXML utilities only for raw themes, relationships, notes, comments, animations, media, masters, or layouts that high-level extraction cannot expose.
- Record inspected parts and parsing exceptions in the analysis manifest.
- Do not use extracted content, fonts, images, or proprietary assets in a generated deck without explicit permission and license evidence.
OOXML package inspection
Install defusedxml from requirements.txt before using the bundled utilities.
- Run
scripts/inspect.py <deck.pptx>for a compact JSON report of slide order, text, theme tokens, relationships, notes, comments, animations, and media. - Run
scripts/validate_package.py <deck.pptx> --output <report.json>for malformed XML, broken internal relationships, content-type gaps, duplicate layout links, and orphaned parts. - Run
scripts/unpack.py <deck.pptx> <output-dir>only when raw-package evidence is necessary. - Resolve relationship targets relative to the
.relsowner; never infer slide order from filenames.
Safety
- Never modify a supplied deck or blindly copy package parts into a new deck.
- Run the scripts from a trusted workspace; they reject path traversal, symlinks, oversized members, and archive bombs.
- Parse untrusted XML with
defusedxml; do not enable entity expansion, DTD loading, or network access. - Treat theme colors as tokens unless fully resolved against the color scheme.
What ships with it
7 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.

pptx-reference-deck-analysis is a skill published in the GitHub repository kimtth/agent-pptify-kit (1 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 572 once invoked, about $0.0002 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 2026-08-30.
