Subject: [PATCH] fix: save research silently via background Bash, not Write
 tool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Write tool displays "Wrote N lines..." after the invitation,
ruining the end-of-run experience. Now saves via background Bash
with a subtle 📎 footer line in the invitation text.

-   ```bash
-   mkdir -p ~/Documents/Last30Days

+**Generate the filename** from TOPIC:
+- Lowercase, replace spaces/special chars with hyphens, remove consecutive hyphens, trim to 60 chars
+- Example: "Claude Code Best Practices" → `claude-code-best-practices.md`
+- If file already exists, append today's date: `{slug}-YYYY-MM-DD.md`

+**CRITICAL RULES:**
+1. NEVER use the `Write` tool — it displays "Wrote N lines..." which ruins the experience
+2. ALWAYS use `run_in_background: true` so the Bash call is nearly invisible
