Code Review: EP59 Episode Addition

Overview

This PR adds a new podcast episode file (ep59.mdx) following the established content pattern. The structure is consistent with recent episodes like EP58.

---

✅ What Looks Good

• Frontmatter fields are complete and match the content schema conventions
• Categories (javascript, programming, node, bun) are accurate and discoverable
• biliUrl uses the same protocol-relative URL format (//player.bilibili.com/...) as other episodes
• publicationDate aligns with today's date (2026-04-17)
• pnpm astro check reportedly passes

⚠️ Issues & Suggestions

1. size: 0 and duration: 0 — Missing audio metadata
Both fields are placeholders. While this is consistent with recent episodes (EP58 also has 0), these values affect RSS feed quality. Podcast clients display duration to listeners, and feed validators may flag duration: 0. If the audio file is already hosted, these should be filled in.

2. Factual claim in show notes needs verification

前几个月又刚被 Anthropic 买下来

This states Bun was recently acquired by Anthropic. This is a notable factual claim — please verify this is accurate before publishing, as incorrect acquisition claims could mislead listeners.

3. excerpt duplicates the full title verbatim

title:   EP59 比 Node 快 3 倍的 Bun 能替 Node 打工吗？
excerpt: EP59 比 Node 快 3 倍的 Bun 能替 Node 打工吗？

This is consistent with other episodes but is a missed opportunity. A distinct excerpt (e.g., a one-sentence summary from the show notes) would improve RSS feed previews and SEO. Low priority since it matches existing convention.

4. Test plan items unchecked
The PR's test plan has two unchecked items:

• [ ] Verify /posts/ep59 page renders locally
• [ ] Verify new entry shows up in /rss.xml

These are quick local checks — please complete them before merging.

Summary

The change is straightforward and follows project conventions. The main blockers before merge:

1. Verify the Anthropic/Bun acquisition claim in the show notes
2. Complete the local render and RSS checks from the test plan
3. Consider filling in duration if the audio is already available
