The following comment was made by an LLM, it may be inaccurate:

Based on the search results, the current PR #13779 "Update config.mdx" appears to be the only PR with that exact title. While there are several related PRs that involve configuration documentation:

• docs: document ~/.opencode as valid global config directory #6174 - "docs: document ~/.opencode as valid global config directory"
• docs(config): clarify pruning behavior and disable options #13110 - "docs(config): clarify pruning behavior and disable options"

However, these are older PRs that address specific config documentation aspects rather than being direct duplicates of PR #13779. The search results show #13779 appearing first in all queries, and no other open PR has the identical "Update config.mdx" title.

No duplicate PRs found
