name	spec-workflow
description	This skill should be used when the user asks to "build a feature", "create a spec", "start spec-driven development", "run research phase", "generate requirements", "create design", "plan tasks", "implement spec", "check spec status", "triage a feature", "create an epic", "decompose a large feature", or needs guidance on spec-driven development workflow, phase ordering, or epic orchestration.

Spec Workflow

Spec-driven development transforms feature requests into structured specs through sequential phases, then executes them task-by-task.

Decision Tree: Where to Start

Situation	Command
New feature, want guidance	/ralph-specum:start <name> <goal>
New feature, skip interviews	/ralph-specum:start <name> <goal> --quick
Large feature needing decomposition	/ralph-specum:triage <goal>
Resume existing spec	/ralph-specum:start (auto-detects)
Jump to specific phase	/ralph-specum:<phase>

Single Spec Flow

start/new -> research -> requirements -> design -> tasks -> implement

Each phase produces a markdown artifact in ./specs/<name>/. Normal mode pauses for approval between phases. Quick mode runs all phases then auto-starts execution.

Phase Commands

Command	Agent	Output	Purpose
/ralph-specum:research	research-analyst	research.md	Explore feasibility, patterns, context
/ralph-specum:requirements	product-manager	requirements.md	User stories, acceptance criteria
/ralph-specum:design	architect-reviewer	design.md	Architecture, components, interfaces
/ralph-specum:tasks	task-planner	tasks.md	POC-first task breakdown
/ralph-specum:implement	spec-executor	commits	Autonomous task-by-task execution

Epic Flow (Multi-Spec)

For features too large for a single spec, use epic triage to decompose into dependency-aware specs.

triage -> [spec-1, spec-2, spec-3...] -> implement each in order

Entry points:

• /ralph-specum:triage <goal> -- create or resume an epic
• /ralph-specum:start -- detects active epics, suggests next unblocked spec

File structure:

specs/
  _epics/<epic-name>/
    epic.md            # Triage output (vision, specs, dependency graph)
    research.md        # Exploration + validation research
    .epic-state.json   # Progress tracking across specs
    .progress.md       # Learnings and decisions

Management Commands

Command	Purpose
/ralph-specum:status	Show all specs and progress
/ralph-specum:switch <name>	Change active spec
/ralph-specum:cancel	Cancel active execution
/ralph-specum:refactor	Update spec files after execution

Common Workflows

Quick prototype

/ralph-specum:start my-feature "Build X" --quick
# Runs all phases automatically, starts execution

Guided development

/ralph-specum:start my-feature "Build X"
# Interactive interviews at each phase
# Review and approve each artifact
/ralph-specum:implement

Large feature

/ralph-specum:triage "Build entire auth system"
# Decomposes into: auth-core, auth-oauth, auth-rbac
/ralph-specum:start  # Picks next unblocked spec
