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 | $0.00025 | $0.00426 |
| Opus 5 | $0.00013 | $0.00213 |
| Sonnet 5 | $0.00005 | $0.00085 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
pptx-slide-specification 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 6d 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.
What it actually says
PPTX Slide Specification
Author final coordinates directly in layout_tree. No renderer may decide placement, shrink text, or infer layout after the audit.
Required contract
- The root JSON contains
summaryandslides. - Every slide has a stable
id, a message-ledtitle, an accessibility reading order, and a completelayout_tree. - A layout tree declares slide size, root group, id-keyed groups and objects, final inch bboxes, styles, z-indexes, and classifications.
- Every meaningful object has
id,kind,role,classification,content,style,bbox, andz_index. - Production
summarycontains an explicitlayout_policy(safe margin, content bottom, footer top, minimum gap) and accessibility metadata.
Authoring rules
- Use stable readable IDs, absolute groups, and positive inch dimensions.
- Keep normal content inside the safe margin and above the footer rail. Only background
layout_designobjects may be full bleed. - Use native
text,shape,line,table, andimageobjects. Recreate labels and values from any supporting visual as native objects. - Give meaningful images alt text. Record
source_reffor sourced claims. - Keep content text at 9 pt or greater; shorten, resize, or split dense content before reducing type.
- Use shared grids, consistent gaps, explicit color, explicit font size, and an intentional z-order.
Build contract
A task-local builder starts from a blank slide layout and maps all bboxes with Inches(...). Explicitly set wrapping, disabled auto-size, text insets, anchors, alignment, fonts, colors, line settings, image aspect ratio, and hidden-slide state. Reject zero or negative geometry before adding an object.
See references/layout-contract.md for the compact schema and repair guidance.
What ships with it
1 file 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-slide-specification is a skill published in the GitHub repository kimtth/agent-pptify-kit (1 stars, last pushed 1mo ago), licensed MIT. It adds 25 tokens to every session and 426 once invoked, about $0.0001 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.
