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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00038 | $0.00457 |
| Opus 5 | $0.00019 | $0.00229 |
| Sonnet 5 | $0.00008 | $0.00091 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
pptx-review 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 5d 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 Review
Use this skill when the user wants to inspect, summarize, plan, or modify an existing .pptx presentation.
Default Review Workflow
- Call
office_inspectto confirm the file is.pptxand read capability boundaries. - Call
office_previewfor slide titles and extracted bullets. - Call
office_extract_irwhen you need stable slide ids and a fuller structured view. - Summarize the deck, identify weak slides, or propose revisions from the extracted structure.
Current V1 Limitation
Built-in .pptx support is read-only. Do not pretend that office_apply_ops exists for presentations.
Write Workflow
If the user needs a new deck, prefer slides/slidev-deck first unless the .pptx file itself is the required authoring format.
If the user still needs direct .pptx creation or modification, prefer write_file + execute_code with python-pptx.
Use a script when the task involves:
- creating a new deck from notes or markdown
- replacing titles or bullet lists
- generating status, report, or pitch slides
- producing a deliverable
.pptxinstead of only an edit plan
When using a script:
- save to a new
.pptxpath - keep the slide structure explicit: title plus bullet content or simple content blocks
- print the output path and slide count
- be clear that exact themes, animations, notes, and advanced layout geometry may still need manual polish
See PPTX.md for a script pattern.
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-review is a skill published in the GitHub repository matingai/crab (4 stars, last pushed 2mo ago), licensed MIT. It adds 38 tokens to every session and 457 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 2026-08-31.
