+# GitHub Issue Triage
+
+When given a GitHub issue or discussion URL, follow this process:
+
+## 1. Check Git History FIRST (before reading issue details)
+
+```bash
+# Search for commits referencing the issue number or related keywords
+git log --all --since="30 days ago" --format="%h %ai %s" | grep -i "keywords|from|issue"
+git log --all --oneline | grep -i "#123\|relevant-keywords" | head -20
+```
+
+- Look for commits that reference the issue number
+- Check if the issue was already addressed
+- Understand recent development context
+
+## 2. Read ALL Comments
+
+```bash
+gh issue view 123 --repo owner/repo --json comments --jq '.comments[] | "\(.author.login) (\(.createdAt)): \(.body)"'
+```
+
+- NEVER respond based on partial context
+- Later comments often contain critical context
+- Check if users confirmed fixes or provided updates
+
+## 3. Establish Timeline
+
+- When was the issue created?
+- What commits happened after?
+- Did users comment after commits to confirm/deny fixes?
+
+## 4. Challenge the Premise
+
+- Does this request make sense architecturally?
+- What are the security implications?
+- Is this solving the right problem?
+- Does similar functionality already exist?
+- Is there a configuration or documentation solution instead?
+
+## 5. Commit Message Rules
+
+- Reference issues: "Related to #123" or "Addresses #123"
+- NEVER use auto-close keywords: "Fixes #123", "Closes #123", "Resolves #123"
+- Users must verify fixes before issues are closed
+
+## 6. Comment Style (when writing responses)
+
+- Direct but user-friendly, write for typical users not developers
+- No "we", "us", "our"
+- No exclamation marks or enthusiasm
+- No bullets/dashes for lists
+- No pleasantries ("hope this helps", "let me know")
+- Use hedging when uncertain: "might", "could", "possibly"
+- For fixes: just say "This will be in the next release"
+- NEVER say "build from source" or "pull latest"
+- Match the user's effort level in your response
