Review Summary

This is a well-written changelog entry that closely follows the established pattern from the v0.5.0 changelog. One minor fix was applied.

Fix applied

• Unused import (line 10): Removed WranglerConfig from the import statement — it was imported but never used in the file. This could cause a build warning or linting error.

What passed review

Category	Status
Frontmatter	All required fields present. title, description, date valid. products references (agents, workers) are valid directory entries.
File path	src/content/changelog/agents/2026-02-25-agents-sdk-v0.6.0.mdx follows the {YYYY-MM-DD}-{slug}.mdx convention.
Writing style	Active voice, present tense, no contractions, no e.g./i.e., no LLM-isms. Consistent with the v0.5.0 entry.
MDX syntax	No unescaped {, }, <, > in prose. :::note admonition is properly closed.
Code blocks	All use ts or sh — valid lowercase language identifiers. No $ prefix on shell commands.
Code examples	TypeScriptExample components properly wrap the code blocks for the API changes (RPC transport, optional OAuth).
Heading hierarchy	H2 sections (##) with one H3 (### Upgrade) under the last H2 — matches the v0.5.0 structure exactly.
Links	External GitHub links are appropriate for the SDK repo and tracking issue. No internal doc links needed fixing.
Consistency	Structure, tone, and the ### Upgrade footer with npm i agents@latest all match the prior agents SDK changelogs.

No other issues found. The entry is clean and ready to merge.

/bonk fix the build

[ask-bonk]

Content syncs successfully now. The fix is straightforward:

Root cause: The title and description frontmatter values contained unquoted colons (: ), which YAML interprets as mapping indicators. This caused a bad indentation of a mapping entry parse error at line 2, column 24 — right at v0.6.0: RPC.

Fix: Wrapped both title and description values in double quotes so YAML treats them as plain strings.
