# /memory:docs-related-cli

Generate CLI documentation for modules affected by git changes using batched agent execution with automatic tool fallback.

## Overview

The `/memory:docs-related-cli` command generates documentation only for modules affected by recent git changes, providing faster documentation updates for daily development.

**Parameters**:
- `--tool <gemini|qwen|codex>`: Primary tool (default: gemini)

**Execution Flow**:
1. Change Detection → 2. Plan Presentation → 3. Batched Generation → 4. Verification

## Features

- **Changed Module Detection** - Uses git diff to identify affected modules
- **Intelligent Batching** - Groups modules by depth (4 modules/agent)
- **Automatic Fallback** - gemini→qwen→codex on failure
- **Depth Sequential** - Process depths N→0, parallel batches within depth
- **Smart Filtering** - Auto-detects and skips tests/build/config/docs
- **Single Strategy** - Uses single-layer documentation for speed

## Usage

```bash
# Generate docs for changed modules
/memory:docs-related-cli

# Use specific tool
/memory:docs-related-cli --tool qwen
```

## Tool Fallback Hierarchy

```javascript
--tool gemini  →  [gemini, qwen, codex]  // default
--tool qwen    →  [qwen, gemini, codex]
--tool codex   →  [codex, gemini, qwen]
```

## Execution Flow

### Phase 1: Change Detection & Analysis

```javascript
// Detect changed modules
Bash({command: "ccw tool exec detect_changed_modules '{\"format\":\"list\"}'", run_in_background: false});

// Cache git changes
Bash({command: "git add -A 2>/dev/null || true", run_in_background: false});
```

**Parse output** `depth:N|path:<PATH>|change:<TYPE>` to extract affected modules.

**Smart filter**: Auto-detect and skip tests/build/config/docs based on project tech stack.

**Fallback**: If no changes detected, use recent modules (first 10 by depth).

### Phase 2: Plan Presentation

- Parse `--tool` (default: gemini)
- Refresh code index for accurate change detection
- Detect changed modules
- **Smart filter modules** (auto-detect tech stack, skip tests/build/config)
- Cache git changes
- Apply fallback if no changes
- Construct tool fallback order
- **Present filtered plan** with change types
- **Wait for y/n confirmation**

### Phase 3: Batched Documentation Generation

```javascript
let modules_by_depth = group_by_depth(changed_modules);
let tool_order = construct_tool_order(primary_tool);

for (let depth of sorted_depths.reverse()) {  // N → 0
  let batches = batch_modules(modules_by_depth[depth], 4);

  for (let batch of batches) {
    let parallel_tasks = batch.map(module => {
      return async () => {
        for (let tool of tool_order) {
          Bash({
            command: `cd ${module.path} && ccw tool exec generate_module_docs '{"strategy":"single","sourcePath":".","projectName":"${project_name}","tool":"${tool}"}'`,
            run_in_background: false
          });
          if (bash_result.exit_code === 0) {
            report(`✅ ${module.path} docs generated with ${tool}`);
            return true;
          }
        }
        report(`❌ FAILED: ${module.path} failed all tools`);
        return false;
      };
    });
    await Promise.all(parallel_tasks.map(task => task()));
  }
}
```

### Phase 4: Verification

- Verify documentation files were created
- Display statistics
- Show summary of generated docs

## Strategy Selection

**Related Mode** uses `single` strategy:
- Generates single document per module
- Faster than full mode's multi-layer approach
- Suitable for iterative development

## Comparison with Full CLI Documentation

| Aspect | Related Docs | Full Docs |
|--------|--------------|-----------|
| **Scope** | Changed modules only | All project modules |
| **Speed** | Fast (minutes) | Slower (10-30 min) |
| **Use case** | Daily development | Major refactoring |
| **Strategy** | single only | full for depth>=3 |
| **Trigger** | After commits | After major changes |
| **Batching** | 4 modules/agent | 4 modules/agent |
| **Fallback** | gemini→qwen→codex | gemini→qwen→codex |

## Examples

### Basic Usage

```bash
# Document changed modules after commits
/memory:docs-related-cli

# Output:
# Detecting git changes...
# Found 8 changed modules
# Filtered: 3 test modules skipped
# Plan: Generate docs for 5 modules
# Confirm? (y/n): y
#
# Depth 3: [4/4] ✅
# Depth 2: [1/1] ✅
# Summary: 5/5 modules documented
```

### Tool Selection

```bash
# Use Qwen for generation
/memory:docs-related-cli --tool qwen
```

- **/memory:update-related** - Update CLAUDE.md for changed modules
- **/memory:compact** - Compact session memory

## Notes

- **Smart filtering** automatically skips test/build/config directories
- **Change detection** uses git diff to find affected modules
- **Single strategy** optimizes for speed in iterative development
- **Tool fallback** ensures completion even if primary tool fails
- **Verification** confirms all documentation files created successfully
