Code Review: EP62 Episode Content

Note: This PR has already been merged. The following is a post-merge review for record-keeping and future guidance.

---

Overview

This PR adds a single MDX file for EP62 — a short episode on prompt engineering best practices with AI. The changes are purely additive content with no logic changes.

---

✅ What looks good

• Follows established conventions: The frontmatter structure, field names, and shownote formatting all match the existing episodes (e.g. ep61).
• Chinese content: All copy is in Chinese as required by the project.
• Multi-platform links: Includes 小宇宙 (xyzLink), YouTube (youtubeId), and Bilibili (biliUrl), consistent with recent episodes.
• Category tagging: Categories are relevant and descriptive (ai, prompt-engineering, claude, productivity).

⚠️ Issues / Observations

1. size: 0 and duration: 0 are placeholders

These fields are 0 in ep61 and ep62, which appears to be an established pattern — but it's worth noting that size (file size in bytes) and duration (in seconds) are standard RSS 2.0 podcast fields. Leaving them as 0 can degrade compatibility with some podcast clients (e.g. duration display, progress bars) and may violate Podcast Index or Apple Podcasts ingestion rules.

Suggestion: Consider updating these after publishing, or auto-deriving them in the RSS feed generator using the actual audio file metadata.

2. biliUrl uses a protocol-relative URL

biliUrl: //player.bilibili.com/player.html?...

Protocol-relative URLs (//) work in browsers but can break in server-side rendering, RSS feeds, or tooling that doesn't assume https. This pattern is also present in ep61, so it's established — but it's a latent risk.

Suggestion: Prefer https://player.bilibili.com/... for correctness and safety.

3. excerpt duplicates title

title: "EP62 聊聊 Prompt: 少点套路，多点效率"
excerpt: "EP62 聊聊 Prompt: 少点套路，多点效率"

The excerpt field likely renders in search results, RSS descriptions, and meta tags. A copy of the title provides no additional context.

Suggestion: Write a 1–2 sentence summary for excerpt (e.g. drawing from the shownotes: "这期聊如何更高效地和 AI 沟通——减少复杂套路，增加清晰表达"). This improves SEO and podcast platform previews.

---

💡 Minor Notes

• The title field uses quotes ("EP62 聊聊 Prompt: 少点套路，多点效率") while ep61 does not quote its title. Either is valid YAML, but keeping the style consistent is preferable.
• subtitle intentionally omits the EP62 prefix — this is fine and matches ep61's pattern.

---

Summary

The PR is a clean content addition that follows existing conventions. The only actionable concerns are the size/duration placeholder issue (affects podcast client compatibility) and the excerpt duplication (minor SEO impact). Both are pre-existing patterns in the repo and worth addressing systematically across all episodes rather than one-off.
