The skill is mostly efficient and covers a lot of ground, but some sections could be tightened. The PDF-to-PPTX conversion script and some explanatory text (e.g., 'Every business is becoming a real-time business' in the example) add bulk. The speaker notes section, while important, repeats the warning about colons/em dashes three times. However, most content earns its place given the complexity of presenterm's format.

Excellent actionability throughout — concrete YAML frontmatter examples, exact comment command syntax in a reference table, executable code blocks for PDF export and PPTX conversion, specific CLI commands, and a complete end-to-end example presentation. Everything is copy-paste ready with real syntax.

The skill clearly sequences the workflow: frontmatter → slides → content features → running/exporting. The speaker notes section includes an explicit validation step ('mentally scan for : and —') with wrong/right examples. The export workflow has clear steps with config file creation, and the troubleshooting note about diagram renderers showing as plain code provides error recovery guidance.

Excellent progressive disclosure — the main file serves as a comprehensive but navigable overview, with four clearly signaled one-level-deep references (mermaid.md, d2.md, themes.md, design-patterns.md). The reference table at the top and inline links throughout make navigation easy. Content is appropriately split between the main skill and reference files.

Lists multiple specific concrete capabilities: 'terminal-based presentation slides', 'themes, code highlighting, images, column layouts, speaker notes'. Also mentions specific actions like 'create', 'convert content into presenterm format'.

Clearly answers both 'what' (create terminal-based presentation slides using presenterm's markdown format with themes, code highlighting, etc.) and 'when' (explicit 'Use this skill whenever...' clause with multiple trigger scenarios including edge cases).

Excellent coverage of natural trigger terms: 'presenterm', 'terminal slides', 'markdown slides', 'terminal presentation', 'markdown presentation', 'slide deck in markdown', 'create a presentation'. Covers both the tool name and generic phrasings users would naturally use.

While 'presenterm' is highly distinctive, the description also claims triggers like 'create a presentation' and 'markdown presentation' which could easily conflict with general presentation skills (e.g., PowerPoint/pptx creation). The conditional 'if they have used presenterm before' helps but still creates overlap risk.
