Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 4 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
What it costs to keep this loaded
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 | $0.00041 | $0.03100 |
| Opus 5 | $0.00020 | $0.01550 |
| Sonnet 5 | $0.00008 | $0.00620 |
| Haiku 4.5 | $0.00004 | $0.00310 |
Grade A, and why
pptx 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 8d 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 — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Creating from Scratch — html2pptx Workflow
O metodo mais confiavel para criar PPTX do zero:
- Gerar HTML com slides como sections
- Converter HTML -> PPTX via LibreOffice
- Refinar via OOXML editing se necessario
# 1. Create HTML file with slide content
cat > /tmp/slides.html << 'HTMLEOF'
<!DOCTYPE html>
<html>
<head><style>
.slide { page-break-after: always; padding: 40px; font-family: Arial; }
h1 { color: #1a1a2e; font-size: 36px; }
h2 { color: #16213e; font-size: 28px; }
ul { font-size: 20px; line-height: 1.8; }
.subtitle { color: #666; font-size: 18px; }

# 2. Convert to PPTX
libreoffice --headless --convert-to pptx /tmp/slides.html --outdir /tmp/
# 3. Verify
ls -la /tmp/slides.pptx
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 is a skill published in the GitHub repository andregusman-raiz/a-gusman-claude (19 stars, last pushed 2d ago), licensed MIT. It adds 41 tokens to every session and 3,100 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 2026-09-03.
