About this capability
Preview Markdown, LaTeX, PDF, or code artifacts when preview commands are visible, or fall back to shell/browser tools. Use when the user wants to review a written artifact, export a report, or view a rendered document.
What this skill tells your AI
The instructions your AI receives, as published by companion-inc/feynman in skills/preview/SKILL.md and read by ahel’s review.
Use /preview only when that command is visible in the active session. If preview commands are unavailable, render or open artifacts with shell/browser tools and report that the preview package is not installed.
