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 →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

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.

Security

Grade C, and why

frontend-slides scanned grade C with 1 finding 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 7d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/assemble-controllers.py, scripts/assemble-layouts.py, scripts/assemble-styles.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Slides Skill

Generate browser-based HTML presentations as a single self-contained .html file. Three entry paths: new build from topic/notes, PPTX-to-HTML conversion, or enhancement of an existing HTML deck.

Routing disambiguation: When the user says only "slides" or "deck" without specifying format, ask exactly one question before proceeding: "Should this be an HTML file (opens in browser) or a PowerPoint file (.pptx)?" This skill only produces HTML — it converts an existing PPTX to HTML but cannot generate a new .pptx file.

Reference Loading Table

Signal Load These Files Why

PPTX, .pptx, python-pptx, convert slides, extract slides references/pptx-conversion.md Safe extraction loop, notes guard, GROUP shape recursion, base64 image embedding, error-fix mappings

Instructions

Phase 1: DETECT

Identify which of the three paths applies:

Path Signal Action
New build User provides topic, outline, or notes -- no existing file Proceed to Phase 2 to gather content
PPTX conversion User provides a .pptx file path Extract with python-pptx; collect slides, notes, and asset order; then proceed to Phase 3
HTML enhancement User provides an existing .html deck Read the file; identify what needs improving; skip to Phase 4

GATE 1: Do not proceed without identifying the path. If the input is ambiguous (e.g., "make me a deck" with no file and no topic), ask one question to resolve it.
