Simon Willison hides AI PR descriptions in details/summary tags
Simon Willison · rss · 2026-11-09
Simon Willison shares a low-effort trick for managing PRs opened by coding agents like Claude Code and Codex.
- The problem: agent-written PR descriptions are accurate and comprehensive but read like slop—readers (including the author himself) instantly tune out.
- The fix: GitHub Markdown supports <details><summary>. He hand-writes a short, human-curated opener (sometimes with a screenshot) explaining what the PR is for, then collapses the full agent-written essay under a summary headed by the model name and effort level, e.g. "Claude Opus 5.5 Medium".
- The information stays intact, but readers get a human-judged top-level view without wading through paragraphs of agent prose. He links several real datasette/llm PRs as examples.
- Bonus mnemonic: say "details-summary" (2+3 syllables) to never mix up the tag order; he also wishes GitHub added an editor button for this.
