/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)
  ↓
codeagent analysis (plan mode + UI auto-detection)
  ↓
dev-plan-generator (create dev doc)
  ↓
codeagent concurrent development (25 tasks, backend split)
  ↓
codeagent 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
  • 23 rounds of Q&A until the requirement is clear

2. codeagent Analysis & UI Detection

  • Call codeagent to analyze the request in plan mode style
  • Extract: core functions, technical points, task list (25 items)
  • UI auto-detection: needs UI work when task involves style assets (.css, .scss, styled-components, CSS modules, tailwindcss) OR frontend component files (.tsx, .jsx, .vue); output yes/no plus evidence

3. Generate Dev Doc

  • Call the dev-plan-generator agent
  • Produce a single dev-plan.md
  • Append a dedicated UI task when Step 2 marks needs_ui: true
  • Include: task breakdown, file scope, dependencies, test commands

4. Concurrent Development

  • Work from the task list in dev-plan.md
  • Use codeagent per task with explicit backend selection:
    • Backend/API/DB tasks → --backend codex (default)
    • UI/style/component tasks → --backend gemini (enforced)
  • Independent tasks → run in parallel
  • Conflicting tasks → run serially

5. Testing & Verification

  • Each codeagent task:
    • Implements the feature
    • Writes tests
    • Runs coverage
    • Reports results (≥90%)

6. Complete

  • Summarize task status
  • Record coverage

Usage

/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
  • codeagent skill: analysis, development, testing; supports --backend for codex (default) or gemini (UI)
  • dev-plan-generator agent: generate dev doc (subagent via Task tool, saves context)

UI Auto-Detection & Backend Routing

  • UI detection standard: style files (.css, .scss, styled-components, CSS modules, tailwindcss) OR frontend component code (.tsx, .jsx, .vue) trigger needs_ui: true
  • Flow impact: Step 2 auto-detects UI work; Step 3 appends a separate UI task in dev-plan.md when detected
  • Backend split: backend/API tasks use codex backend (default); UI tasks force gemini backend
  • Implementation: Orchestrator invokes codeagent skill with appropriate backend parameter per task type

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

  • 25 tasks in parallel
  • Auto-detect dependencies and conflicts
  • codeagent executes independently

Quality Assurance

  • Enforces 90% coverage
  • codeagent tests and verifies its own work
  • Automatic retry on failure

Example

# 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: codeagent analysis
Output:
- Core: email/password login + JWT auth
- Task 1: Backend API
- Task 2: Password hashing
- Task 3: Frontend form
UI detection: needs_ui = true (tailwindcss classes in frontend form)

# Step 3: Generate doc
dev-plan.md generated with backend + UI tasks ✓

# Step 4-5: Concurrent development (backend codex, UI gemini)
[task-1] Backend API (codex) → tests → 92% ✓
[task-2] Password hashing (codex) → tests → 95% ✓
[task-3] Frontend form (gemini) → tests → 91% ✓

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 codeagent
  5. No legacy baggage: clean-slate design

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