+name: summarize
+description: Summarize and save the current session context

+---
+
+# /summarize Command
+
+Summarize the current session and save key information to memory.
+
+## When Invoked
+
+Extract and save important information from the current conversation:
+
+1. **Decisions made** → `memory/decisions.json`
+2. **Preferences learned** → `memory/preferences.json`
+3. **Project context** → `memory/projects.json`
+4. **Facts discovered** → `memory/facts.json`
+
+## Process
+
+### Step 1: Analyze Session
+
+Review the conversation for:
+- Explicit decisions ("let's use X", "we decided Y")
+- Implicit preferences ("I prefer", "always do X")
+- Project-related context (paths, configs, conventions)
+- Facts about the environment or user
+
+### Step 2: Categorize Items
+
+For each item, determine:
+- **Category**: decision, preference, project, fact
+- **Content**: Brief description
+- **Context**: Why it matters (optional)
+
+### Step 3: Save to Memory
+
+Append to the appropriate memory file:
+
+```json
+{
+  "id": "uuid",
+  "date": "YYYY-MM-DD",
+  "content": "Description of item",
+  "context": "Additional context",
+  "session": "session-id"
+}
+```
+
+### Step 4: Update History Index
+
+Mark session as summarized in `history/index.json`:
+
+```json
+{
+  "sessions": [
+    {
+      "id": "session-id",
+      "started": "timestamp",
+      "summarized": true
+    }
+  ]
+}
+```
+
+## Output Format
+
+```
+📝 Session Summary
+
+Saved to memory:
+• Decision: Use plugin structure for .claude config
+• Preference: Prefer scripts over inline code in skills
+• Fact: Gmail venv at ~/.claude/mcp/gmail/venv
+
+Session marked as summarized.
+```
+
+## Memory File Locations
+
+| File | Content |
+|------|---------|
+| `~/.claude/state/personal-assistant/memory/decisions.json` | Choices made |
+| `~/.claude/state/personal-assistant/memory/preferences.json` | User preferences |
+| `~/.claude/state/personal-assistant/memory/projects.json` | Project context |
+| `~/.claude/state/personal-assistant/memory/facts.json` | Environment facts |
+
+## When to Use
+
+- End of a productive session
+- After making important decisions
+- When asked to "remember this"
+- Before long breaks
+
+## Policy
+
+- Only save genuinely useful information
+- Avoid redundancy with existing memory
+- Keep descriptions concise
+- Include context when helpful
