# /dev - Minimal Dev Workflow

## Overview

A freshly designed lightweight development workflow with no legacy baggage, focused on delivering high-quality code fast.

## Flow

```
/dev trigger
  ↓
AskUserQuestion (requirements clarification)
  ↓
Codex analysis (extract key points and tasks)
  ↓
develop-doc-generator (create dev doc)
  ↓
Codex concurrent development (2–5 tasks)
  ↓
Codex testing & verification (≥90% coverage)
  ↓
Done (generate summary)
```

## The 6 Steps

### 1. Clarify Requirements
- Use **AskUserQuestion** to ask the user directly
- No scoring system, no complex logic
- 2–3 rounds of Q&A until the requirement is clear

### 2. Codex Analysis
- Call codex to analyze the request
- Extract: core functions, technical points, task list (2–5 items)
- Output a structured analysis

### 3. Generate Dev Doc
- Call the **develop-doc-generator** agent
- Produce a single `dev-plan.md`
- Include: task breakdown, file scope, dependencies, test commands

### 4. Concurrent Development
- Work from the task list in dev-plan.md
- Independent tasks → run in parallel
- Conflicting tasks → run serially

### 5. Testing & Verification
- Each codex task:
  - Implements the feature
  - Writes tests
  - Runs coverage
  - Reports results (≥90%)

### 6. Complete
- Summarize task status
- Record coverage

## Usage

```bash
/dev "Implement user login with email + password"
```

**No options**, fixed workflow, works out of the box.

## Output Structure

```
.claude/specs/{feature_name}/
└──  dev-plan.md      # Dev document generated by agent
```

Only one file—minimal and clear.

## Core Components

### Tools
- **AskUserQuestion**: interactive requirement clarification
- **codex**: analysis, development, testing
- **develop-doc-generator**: generate dev doc (subagent, saves context)

## Key Features

### ✅ Fresh Design
- No legacy project residue
- No complex scoring logic
- No extra abstraction layers

### ✅ Minimal Orchestration
- Orchestrator controls the flow directly
- Only three tools/components
- Steps are straightforward

### ✅ Concurrency
- 2–5 tasks in parallel
- Auto-detect dependencies and conflicts
- Codex executes independently

### ✅ Quality Assurance
- Enforces 90% coverage
- Codex tests and verifies its own work
- Automatic retry on failure

## Example

```bash
# Trigger
/dev "Add user login feature"

# Step 1: Clarify requirements
Q: What login methods are supported?
A: Email + password
Q: Should login be remembered?
A: Yes, use JWT token

# Step 2: Codex analysis
Output:
- Core: email/password login + JWT auth
- Task 1: Backend API
- Task 2: Password hashing
- Task 3: Frontend form

# Step 3: Generate doc
dev-plan.md generated ✓

# Step 4-5: Concurrent development
[task-1] Backend API → tests → 92% ✓
[task-2] Password hashing → tests → 95% ✓
[task-3] Frontend form → tests → 91% ✓
```

## Directory Structure

```
dev-workflow/
├── README.md                          # This doc
├── commands/
│   └── dev.md                         # Workflow definition
└── agents/
    └── develop-doc-generator.md       # Doc generator
```

Minimal structure, only three files.

## When to Use

✅ **Good for**:
- Any feature size
- Fast iterations
- High test coverage needs
- Wanting concurrent speed-up

## Design Principles

1. **KISS**: keep it simple
2. **Disposable**: no persistent config
3. **Quality first**: enforce 90% coverage
4. **Concurrency first**: leverage codex
5. **No legacy baggage**: clean-slate design

**Philosophy**: zero tolerance for complexity—ship the smallest usable solution, like Linus would.
