majiayu000 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
