+### 1.6 Session Timeline Review (`/thinkback`)
+
+The `/thinkback` command analyzes the current conversation history and generates a structured timeline of key events — decisions made, files modified, and bugs fixed during the session.
+
+| Command                                | Description                                     |
+| -------------------------------------- | ----------------------------------------------- |
+| `/thinkback`                           | Generate a full session timeline                |
+| `/thinkback --from "30 min ago"`       | Only include events from a specific time range  |
+| `/thinkback --topic "auth"`            | Only include events related to a specific topic |
+| `/thinkback --from "1h ago" --topic X` | Combine time range and topic filters            |
+
+**How It Works:**
+
+- The curated conversation history is sent to the LLM with a prompt to extract key events
+- The LLM returns a structured Markdown timeline with numbered steps
+- Each step is categorized as a Decision, Fix, or Change, with affected files noted
+- The command blocks the main conversation while generating (unlike `/btw`)
+
+**Example:**
+
+```
+> /thinkback
+
+# Timeline Review
+- **Step 1** — [Change] Updated auth middleware to fix session token storage (auth.ts)
+- **Step 2** — [Decision] Switched to JWT-based tokens for compliance (config.ts, auth.ts)
+- **Step 3** — [Fix] Resolved token refresh race condition (tokenManager.ts)
+```
+
+With filtering:
+
+```
+> /thinkback --from "30 min ago" --topic "auth"
+
+# Timeline Review
+- **Step 1** — [Fix] Fixed session token storage format for compliance (auth.ts)
+```
+
+**Supported Execution Modes:**
+
+| Mode                 | Behavior                                        |
+| -------------------- | ----------------------------------------------- |
+| Interactive          | Shows pending indicator, then displays timeline |
+| Non-interactive      | Returns timeline as text result                 |
+| ACP (Agent Protocol) | Returns stream_messages async generator         |
+
+> [!tip]
+>
+> Use `/thinkback` at the end of a long session to get a quick recap of everything that happened. It's especially useful before creating a commit message, writing a PR description, or handing off work to a colleague.
