deep-learning-playbook

Write or update section-based interview answer notes for the deep-learning-playbook repository. Use this skill when the user gives one chapter or subsection of questions from `interview/questions.md` and wants matching answer content added under `interview/answer/`, following the repository's concise Markdown style and the CI-required `## 1. 题目原文` answer-heading format.

Import interview questions into `interview/questions.md` for the deep-learning-playbook repository. Use this skill when the user provides a screenshot, OCR result, note, or plain text containing interview questions and wants them classified into the existing sections of `interview/questions.md`, merged with deduplication, optionally folded into nearby existing questions as suffix expansions, and reported as added, skipped, expanded, or unmatched.
