Long Document Handler is a production-ready Claude Code skill (quality score 70/100) in the product-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/long-document-handler/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when encountering large files, lengthy documentation, big markdown documents, massive PRDs, architecture docs, or any content that risks context window overflow. Activates on phrases like "this document is long", "large file", "too many tokens", or when Claude detects document size approaching limits.
The Long Document Handler skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features.
