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
                         ^
                         optional prototype overlay, then return

Each phase produces a markdown artifact under the resolved `<basePath>/`. Normal mode pauses for approval between phases. Quick mode runs all phases then auto-starts execution.

Prototype is an optional overlay, not a main phase. The main `phase` remains `research`, `requirements`, `design`, `tasks`, or `execution`; live prototype work is stored in `activePrototypes`. Resolve the configured spec root and `basePath` before any overlay operation. Follow [`references/phase-transitions.md`](references/phase-transitions.md) when suggesting, starting, resuming, cancelling, or consuming prototype evidence.

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 | | `/ralph-specum:prototype` | prototype-builder | prototypes/&lt;id&gt;.md | Test one falsifiable design question in isolation |

Normal mode may suggest prototype after research or requirements, and the user owns capture, verdict, handoff, and deletion decisions. Direct invocation is available from any main phase. Quick mode runs at most one agent-owned request after requirements, takes over the oldest design blocker when one exists, asks no decision questions, and always continues to design.

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 workflow

/ralph-specum:start my-feature "Build X" --quick
# Runs all phases automatically, starts execution
# May run one unattended prototype request after requirements

Guided development

/ralph-specum:start my-feature "Build X"
# Fact-first grilling 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
