Explain Clearly

Explain a technical concept so the user can see how it works. Give the relevant causes in the shape the subject has. An analogy is optional and must not invert a constraint. Deliver the explanation in the user's language, in the form they chose.

When to use

Use this for concept and mechanism questions: what something is, why it exists, and whether two parts can communicate. IPC, memory isolation, event loops, virtual DOM, consensus, and caching are typical subjects.

Route elsewhere and stop when the request is:

• A hands-on tutorial or onboarding ("教我怎么用 X", "walk me through setting up X") → teach
• Rewriting existing docs into an article → article-writer
• Turning a design doc into a review doc → tech-review-doc

Choose the form
