+**Workflow:**

+1. Create local issue (ISS-YYYYMMDD-NNN) → stored in .workflow/issues.jsonl

+3. Both local and GitHub issues exist, linked together

+**Example with GitHub Publishing:**
+```bash
+# User creates text issue
+/issue:new "Login fails with special chars. Expected: success. Actual: 500"
+
+# System asks: "Would you like to publish this issue to GitHub?"
+# User selects: "Yes, publish to GitHub"
+
+# Output:
+# ✓ Local issue created: ISS-20251229-001
+# ✓ Published to GitHub: https://github.com/org/repo/issues/123
+# ✓ GitHub binding saved to local issue
+# → Next step: /issue:plan ISS-20251229-001
+
+# Resulting issue JSON:
+{
+  "id": "ISS-20251229-001",
+  "title": "Login fails with special chars",
+  "source": "text",
+  "github_url": "https://github.com/org/repo/issues/123",
