# Session Management Commands

## One-Liner

**Session management commands are the workflow state managers** — creating, tracking, resuming, and completing workflow sessions.

## Core Concepts

| Concept | Description | Location |
|---------|-------------|----------|
| **Session ID** | Unique identifier (WFS-YYYY-MM-DD) | `.workflow/active/WFS-xxx/` |
| **Session Type** | workflow, review, tdd, test, docs | Session metadata |
| **Session State** | active, paused, completed | workflow-session.json |
| **Artifacts** | Plans, tasks, TODOs, etc. | Session directory |

## Command List

| Command | Function | Syntax |
|---------|----------|--------|
| [`start`](#start) | Discover existing sessions or start new workflow session | `/workflow:session:start [--type type] [--auto\|--new] [description]` |
| [`list`](#list) | List all workflow sessions | `/workflow:session:list` |
| [`resume`](#resume) | Resume most recently paused workflow session | `/workflow:session:resume` |
| [`complete`](#complete) | Mark active workflow session as completed | `/workflow:session:complete [-y] [--detailed]` |
| [`solidify`](#solidify) | Crystallize session learnings into project guidelines | `/workflow:session:solidify [-y] [--type type] [--category category] "rule"` |

## Command Details

### start

**Function**: Discover existing sessions or start new workflow session, supporting intelligent session management and conflict detection.

**Syntax**:
```
/workflow:session:start [--type <workflow|review|tdd|test|docs>] [--auto|--new] [optional: task description]
```

**Options**:
- `--type=type`: Session type
  - `workflow`: Standard implementation (default)
  - `review`: Code review
  - `tdd`: TDD development
  - `test`: Test generation/fix
  - `docs`: Documentation session
- `--auto`: Smart mode (auto detect/create)
- `--new`: Force create new session

**Session Types**:

| Type | Description | Default Source |
|------|-------------|----------------|
| `workflow` | Standard implementation | workflow-plan skill |
| `review` | Code review | review-cycle skill |
| `tdd` | TDD development | workflow-tdd skill |
| `test` | Test generation/fix | workflow-test-fix skill |
| `docs` | Documentation session | memory-manage skill |

**Workflow**:

```mermaid
graph TD
    A[Start] --> B{Project State Exists?}
    B -->|No| C[Call workflow:init]
    C --> D
    B -->|Yes| D{Mode}
    D -->|Default| E[List Active Sessions]
    D -->|auto| F{Active Sessions Count?}
    D -->|new| G[Create New Session]
    F -->|0| G
    F -->|1| H[Use Existing Session]
    F -->|>1| I[User Selects]
    E --> J{User Selects}
    J -->|Existing| K[Return Session ID]
    J -->|New| G
    G --> L[Generate Session ID]
    L --> M[Create Directory Structure]
    M --> N[Initialize Metadata]
    N --> O[Return Session ID]
```

**Examples**:

```bash
# Discovery mode - list active sessions
/workflow:session:start

# Auto mode - smart select/create
/workflow:session:start --auto "implement user authentication"

# New mode - force create new session
/workflow:session:start --new "refactor payment module"

# Specify type
/workflow:session:start --type review "review auth code"
/workflow:session:start --type tdd --auto "implement login feature"
```

### list

**Function**: List all workflow sessions, supporting state filtering, displaying session metadata and progress information.

**Syntax**:
```
/workflow:session:list
```

**Output Format**:

| Session ID | Type | State | Description | Progress |
|------------|------|-------|-------------|----------|
| WFS-2024-01-15 | workflow | active | User authentication | 5/10 |
| WFS-2024-01-14 | review | paused | Code review | 8/8 |
| WFS-2024-01-13 | tdd | completed | TDD development | 12/12 |

**Examples**:
```bash
# List all sessions
/workflow:session:list
```

### resume

**Function**: Resume most recently paused workflow session, supporting automatic session discovery and state update.

**Syntax**:
```
/workflow:session:resume
```

**Workflow**:

```mermaid
graph TD
    A[Start] --> B[Find Paused Sessions]
    B --> C{Found Paused Session?}
    C -->|Yes| D[Load Session]
    C -->|No| E[Error Message]
    D --> F[Update State to Active]
    F --> G[Return Session ID]
```

**Examples**:
```bash
# Resume most recently paused session
/workflow:session:resume
```

### complete

**Function**: Mark active workflow session as completed, archive and learn from experience, update checklist and remove active flag.

**Syntax**:
```
/workflow:session:complete [-y|--yes] [--detailed]
```

**Options**:
- `--detailed`: Detailed mode, collect more learnings

**Workflow**:

```mermaid
graph TD
    A[Start] --> B[Confirm Completion]
    B --> C{Detailed Mode?}
    C -->|Yes| D[Collect Detailed Feedback]
    C -->|No| E[Collect Basic Feedback]
    D --> F[Generate Learning Document]
    E --> F
    F --> G[Archive Session]
    G --> H[Update Checklist]
    H --> I[Remove Active Flag]
    I --> J[Complete]
```

**Examples**:
```bash
# Standard completion
/workflow:session:complete

# Detailed completion
/workflow:session:complete --detailed

# Auto mode
/workflow:session:complete -y
```

### solidify

**Function**: Crystallize session learnings and user-defined constraints into permanent project guidelines.

**Syntax**:
```
/workflow:session:solidify [-y|--yes] [--type <convention|constraint|learning>] [--category <category>] "rule or insight"
```

**Options**:
- `--type=type`:
  - `convention`: Code convention
  - `constraint`: Constraint condition
  - `learning`: Experience learning
- `--category=category`: Category name (e.g., `authentication`, `testing`)

**Output Locations**:
- Conventions: `.workflow/specs/conventions/<category>.md`
- Constraints: `.workflow/specs/constraints/<category>.md`
- Learnings: `.workflow/specs/learnings/<category>.md`

**Examples**:
```bash
# Add code convention
/workflow:session:solidify --type=convention --category=auth "all auth functions must use rate limiting"

# Add constraint
/workflow:session:solidify --type=constraint --category=database "no N+1 queries"

# Add learning
/workflow:session:solidify --type=learning --category=api "REST API design lessons learned"
```
