+### Multiline Content Management (CRITICAL - HEREDOC RULES)
+
+**🚨 MANDATORY HEREDOC FORMAT:**
 ```bash
-# Uses cat with heredoc for proper shell escaping
-cat <<'EOF' > /tmp/pr-description.md
+# ALWAYS use single quotes around EOF delimiter to prevent variable expansion
+cat << 'EOF' > /tmp/pr-description.md
 ## Summary
-Comprehensive PR description with proper formatting.
+Your PR description content here.
+
+## Implementation Details
+- Bullet points work fine
+- Code blocks with `backticks` are safe
+- Variables like $VAR will NOT be expanded (good!)

-- Multiple lines
-- Code blocks with `backticks`
-- No shell interpretation issues

+# THEN use the file with gh CLI
+gh pr create --title "your title" --body-file /tmp/pr-description.md
 ```
 
+**🚨 CRITICAL RULES:**
+1. **ALWAYS use `cat << 'EOF'`** (with single quotes)
+2. **NEVER use `cat <<EOF`** (without quotes) - causes variable expansion
+3. **NEVER use `cat <<"EOF"`** (with double quotes) - allows some expansion
+4. **NEVER put content directly in `--body`** - use `--body-file` always
+5. **ALWAYS clean up:** `rm /tmp/pr-description.md` after creation

 ## Target Branch Logic

-1. **Remote rc/ branches:** `origin/rc/v0.14.0`
-2. **Local rc/ branches:** `rc/v0.14.0`
-3. **User specification:** Prompts if no rc/ branch found
-4. **Fallback:** Uses repository default branch
+### Branch Priority (CRITICAL - NEVER USE STABLE)
+1. **Remote rc/ branches:** `origin/rc/v0.14.0` - PRIMARY TARGET
+2. **Local rc/ branches:** `rc/v0.14.0` - SECONDARY TARGET  
+3. **User specification:** MANDATORY prompt if no rc/ branch found
+4. **FORBIDDEN:** Never use `stable` branch - PRs to stable are ONLY for version releases
+
+### Branch Detection Rules
+```bash
+# REQUIRED: Always check for rc/ branches first
+RC_BRANCH=$(git branch -r | grep 'origin/rc/' | head -1 | sed 's/.*origin\///')
+if [ -z "$RC_BRANCH" ]; then
+  RC_BRANCH=$(git branch -l | grep 'rc/' | head -1 | sed 's/^[* ] *//')

+  exit 1

 ## Error Recovery
 
+### CRITICAL ERRORS TO AVOID
+
+**🚨 NEVER USE STABLE BRANCH:**
+- **Problem:** Creating PR to `stable` instead of `rc/` branch
+- **Fix:** Always detect and use `rc/` branch as base
+- **Rule:** PRs to `stable` are ONLY for version release merges
+
+**🚨 EOF APPEARING IN PR DESCRIPTION:**
+- **Problem:** Using `cat <<EOF` without quotes causes shell expansion
+- **Fix:** Always use `cat << 'EOF'` with single quotes
+- **Result:** Prevents literal "EOF" text in PR descriptions
+
 ### Common Issues
-- **No rc/ branch:** Prompts user for correct base branch
+- **No rc/ branch:** STOP execution and prompt user - never fallback to stable
 - **Unpushed commits:** Automatically pushes before PR creation
-- **Formatting issues:** Retries with corrected heredoc formatting
+- **Formatting issues:** Use proper heredoc with single quotes around EOF
 - **Label conflicts:** Removes invalid labels and continues
