Spec-Flow

Spec-driven development workflow for AI coding agents

Spec-Flow transforms complex feature development into a guided, phase-by-phase workflow with living documentation. Works with any AI agent that supports the Skills format.

Features

• Phase-by-Phase Workflow: Proposal → Requirements → Design → Tasks → Implementation
• Interactive Confirmation: Each phase waits for your approval before proceeding
• Living Documentation: Creates .spec-flow/ directory with Markdown docs that guide implementation
• EARS Requirements: Industry-standard Easy Approach to Requirements Syntax
• 3 Execution Modes: Step (default), Batch, Phase — choose your speed
• Team Collaboration: Git-friendly, commit specs with your project

Installation

# Claude Code
cd ~/.claude/skills && git clone https://github.com/echoVic/spec-flow.git

# OpenClaw
cd ~/.openclaw/workspace/skills && git clone https://github.com/echoVic/spec-flow.git

# Blade
cd ~/.blade/skills && git clone https://github.com/echoVic/spec-flow.git

# Or any agent's skills directory

Quick Start

Trigger with: spec-flow, spec mode, need a plan, structured development, 写个方案, 做个规划

User: spec-flow — add user authentication

AI: [Creates proposal.md] → waits for confirmation
User: continue
AI: [Creates requirements.md] → waits for confirmation
User: continue
AI: [Creates design.md] → waits for confirmation
User: continue
AI: [Creates tasks.md] → waits for confirmation
User: execute all tasks
AI: [Implements everything]

Parameters: --fast (skip confirmations), --skip-design (simple features)

Five-Phase Workflow

┌──────────┐    ┌──────────────┐    ┌────────┐    ┌───────┐    ┌────────────────┐
│ Proposal │ → │ Requirements │ → │ Design │ → │ Tasks │ → │ Implementation │
└──────────┘    └──────────────┘    └────────┘    └───────┘    └────────────────┘
    WHY              WHAT              HOW        EXECUTE         BUILD

Phase	Goal	Output
Proposal	Define WHY	Background, goals, non-goals, risks
Requirements	Define WHAT	FR/NFR in EARS format, acceptance criteria
Design	Define HOW	Architecture, API, data model (Mermaid)
Tasks	Break down	Granular tasks with dependencies
Implementation	Build	Code, tests, documentation

Execution Modes

Mode	Trigger	Behavior
Step (default)	"start implementation"	One task → confirm → next
Batch	"execute all" / "全部执行"	All tasks consecutively
Phase	"execute setup phase"	All tasks in one phase → confirm
