Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00135 | $0.02132 |
| Opus 5 | $0.00068 | $0.01066 |
| Sonnet 5 | $0.00027 | $0.00426 |
| Haiku 4.5 | $0.00014 | $0.00213 |
Grade A, and why
pptx-slides scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPTX Slides — Programmatic PowerPoint Generation
Generate professional, editable PowerPoint presentations using PptxGenJS (Node.js). Produces OOXML-compliant .pptx files with precise layout, text measurement, and overlap validation.
Bundled Helpers
Every PPTX generation script imports the bundled TypeScript helper modules via bun:
import pptxgen from 'pptxgenjs';
import * as h from '${CLAUDE_PLUGIN_ROOT}/skills/pptx-slides/scripts/main.ts';
const pptx = new pptxgen();
pptx.layout = 'LAYOUT_16x9'; // 10" × 5.625"
Run generation scripts with bun (no build step needed):
npx -y bun ${CLAUDE_PLUGIN_ROOT}/skills/pptx-slides/scripts/main.ts theme list
Dependencies (skia-canvas, fontkit, linebreak, prismjs) are auto-installed by bun on first run — no manual install step needed.

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-slides is a skill published in the GitHub repository proyecto26/slides-ai-plugin (37 stars, last pushed 4mo ago), licensed MIT. It adds 135 tokens to every session and 2,132 once invoked, about $0.0007 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.
