+## Shell Command Patterns
+
+Claude Code's bash execution has quirks. Use these patterns for reliability:
+
+### curl requests
+
+**DO** - Use single quotes for URL and header separately:
+```bash
+curl -s 'https://git.example.com/api/v1/repos/owner/repo/pulls/1/reviews' \
+  -H 'Authorization: token YOUR_TOKEN_HERE' | jq .
+```
+
+**DON'T** - Variable expansion in `-H` flag often fails:
+```bash
+# This may fail with "blank argument" errors
+curl -s -H "Authorization: token $TOKEN" "$URL"
+```
+
+### Iterating over reviews
+
+**DO** - Run separate commands for each review ID:
+```bash
+echo "=== Review 4 ===" && curl -s 'URL/reviews/4/comments' -H 'Authorization: token ...' | jq .
+echo "=== Review 5 ===" && curl -s 'URL/reviews/5/comments' -H 'Authorization: token ...' | jq .
+```
+
+**DON'T** - For loops with multiline bodies often fail:
+```bash
+# This may cause syntax errors
+for id in 4 5 6; do
+  curl -s "URL/reviews/$id/comments"
+done
+```
+
+### tea comment
+
+**DO** - Use single-quoted string for comment body:
+```bash
+tea comment 26 '## Summary
+
+Changes made:
+- Item 1
+- Item 2'
+```
+
+**DON'T** - Heredocs may hang or timeout:
+```bash
+# This may hang indefinitely
+tea comment 26 "$(cat <<'EOF'
+...
+EOF
+)"
+```
+
 ## Limitations
 
 1. **Thread replies**: Gitea API doesn't support inline thread replies. We post a single summary comment instead.
