Anthropic's internal /eli5 trick goes public as a Claude community plugin

A prompt trick commonly used inside Anthropic has been made public: the /eli5 <topic> command asks the model to "explain like the reader knows nothing about the topic," producing an HTML artifact with large visuals and minimal text. It is currently available as a Claude community plugin installable from the community marketplace; whether it becomes an official plugin is still under discussion.

Confirmed

• The /eli5 <topic> command originates from an Anthropic team habit and generates big-picture, low-text HTML artifacts that visualize complex topics
• ELI5 ships as a Claude community plugin via claude plugin install eli5@claude-communi…
• @patricksrail shared a manual install path: first add the community plugin source with claude plugin marketplac…, then install
• Use cases include explaining how a module works, walking through technical trade-offs, and root-causing incidents
• @dairai relayed Omar Sanseviero's recommendation, saying the skill helps visualize deep technical concepts, speed up thinking, and improve collaboration with agents

Unconfirmed

• Per @patricksrail, whether ELI5 becomes an official plugin is still being discussed; it is not built-in today
• @0xkeeny criticized the trick as backwards: users pay tokens to generate verbose output, then pay more tokens to have it simplified—essentially handling a "refund request" rather than an advanced skill; fixing the model's default verbosity would be the real fix

Why it matters

• The trick turns dense textual explanations into visual HTML pages, well suited for quick onboarding and explainer docs; as an insider Anthropic workflow made public, it offers Claude users a ready-to-reuse template
• The criticism also highlights that model conciseness by default remains a more fundamental problem than after-the-fact simplification
