# Memory Capture Skill

Unified memory capture skill that routes to two execution modes:
- **Compact**: Compress full session memory into structured text for recovery
- **Tips**: Quick note-taking for ideas, snippets, and insights

## Architecture Overview

```

## Execution Flow

### Step 1: Parse Input & Route

Detect execution mode from user input:

**Auto-Route Rules** (priority order):

| Signal | Route | Examples |
|--------|-------|---------|
| Keyword: compact, session, 压缩, recovery, 保存会话 | → Compact | "compact current session" |
| Keyword: tip, note, 记录, 快速 | → Tips | "记录一个想法" |
| Has `--tag` or `--context` flags | → Tips | `"note content" --tag bug` |
| Short text (<100 chars) + no session keywords | → Tips | "Remember to use Redis" |
| Ambiguous or no arguments | → **AskUserQuestion** | `/memory-capture` |

**When ambiguous**, use AskUserQuestion:

```
Question: "选择记忆捕获模式"
Options:
  1. Compact - 压缩当前完整会话记忆（用于会话恢复）
  2. Tips - 快速记录一条笔记/想法/提示
```

### Step 2: Execute Selected Phase

Based on routing result, read and execute the corresponding phase:

- **Compact mode** → Ref: [phases/01-compact.md](phases/01-compact.md)
- **Tips mode** → Ref: [phases/02-tips.md](phases/02-tips.md)

**Phase Reference Documents** (read on-demand when phase executes):

| Mode | Document | Purpose |
|------|----------|---------|
| Compact | [phases/01-compact.md](phases/01-compact.md) | Full session memory compression and structured export |
| Tips | [phases/02-tips.md](phases/02-tips.md) | Quick note-taking with tags and context |

### Step 3: Save via core_memory

Both phases converge on the same storage mechanism:

```javascript
mcp__ccw-tools__core_memory({
  operation: "import",
  text: structuredText  // Generated by the selected phase
})
```

## Core Rules

1. **Single Phase Execution**: Only ONE phase executes per invocation - never both
2. **Content Faithful**: Phase files contain full execution detail - follow them verbatim
3. **Absolute Paths**: All file paths in output must be absolute
4. **No Summarization**: Compact mode preserves complete plan verbatim - never abbreviate
5. **Speed Priority**: Tips mode should be fast - minimal analysis overhead

## Input Processing

### Compact Mode Input
- Optional: `"session description"` as supplementary context
- Example: `/memory-capture compact` or `/memory-capture "completed auth module"`

### Tips Mode Input
- Required: `<note content>` - the tip/note text
- Optional: `--tag <tag1,tag2>` for categorization
- Optional: `--context <context>` for related code/feature reference
- Example: `/memory-capture tip "Use Redis for rate limiting" --tag config`

## Data Flow

```
User Input
    │
    ├─ [compact detected] → Read phases/01-compact.md
    │                        → Analyze session → Generate structured text
    │                        → core_memory import → Report Recovery ID
    │
    └─ [tips detected] → Read phases/02-tips.md
                         → Parse args → Gather context → Generate tip text
                         → core_memory import → Confirm with ID + tags
```

## Error Handling

| Error | Action |
|-------|--------|
| core_memory import fails | Retry once, then report error with structured text for manual save |
| No session context (compact) | Warn user, generate with available info |
| Empty note content (tips) | Ask user to provide content via AskUserQuestion |
| Ambiguous routing | Default to AskUserQuestion - never guess |
