Web Research Update

2. Update each selected file

Process files sequentially (not in parallel — respect web search rate limits).

For each file:

1. Read the full current content.
2. Note the existing sources URLs and Key Rules content as the previous baseline.
3. Run 1-2 web searches for the topic (use the topic front-matter field as the search query, supplemented with "best practices" or "security guidelines" as appropriate).
4. Fetch 1-2 of the most authoritative source URLs from the search results.
5. Synthesize updated findings using the same file structure:
   • Update last-researched to today's date
   • Update sources to reflect the URLs actually used
   • Rewrite ## Key Rules, ## Common Pitfalls, ## Relevant to Code Review
6. Before writing, compare new content to previous content. Note additions, removals, and unchanged items.
7. Write the updated file.
8. Report what changed:

   Updated: react-hooks-best-practices.md
   - Added: "Prefer useId over Math.random() for stable IDs"
   - Removed: "Avoid useReducer for simple state" (outdated)
   - Unchanged: 4 rules
   

3. Summarize

After all updates complete, show:

• Count of files updated
• Count of files where content changed vs. stayed the same
• List any topics where advice materially changed (new rules added or old rules removed)
• Suggest running /review again on any active branch if research changed significantly
