# SDLC Studio

Manage project specifications and test artifacts. Supports the full pipeline from PRD creation through Epic decomposition, User Story generation, and streamlined test automation.

## Critical Philosophy (Read This First)

**Two modes for every artifact type:**

| Mode | Purpose | When to Use |
|------|---------|-------------|
| **create** | Author new specifications from user input | Greenfield projects, new features |
| **generate** | Extract specifications from existing code | Brownfield projects, documentation gaps |

> **New to Create vs Generate?** Read `reference-philosophy.md` - it explains why these modes exist and how they differ fundamentally.
>
> **Using generate mode?** You MUST read `reference-philosophy.md#generate-mode` first - generated specs must be validated by tests.

**Generate mode is NOT documentation.** It produces a **migration blueprint** - a specification detailed enough that another team could rebuild the system in a different technology stack. Generated specs MUST be validated by running tests against the existing implementation.

## Quick Start

```bash
/sdlc-studio help                    # Show command reference
/sdlc-studio status                  # Check pipeline state and next steps
/sdlc-studio prd generate            # Create PRD from codebase
/sdlc-studio trd generate            # Create TRD from codebase
/sdlc-studio epic                    # Generate Epics from PRD
/sdlc-studio story                   # Generate Stories from Epics
/sdlc-studio bug                     # Create or list bugs
/sdlc-studio code plan               # Plan implementation for story
/sdlc-studio code implement          # Execute implementation plan
/sdlc-studio code test               # Run tests with traceability
/sdlc-studio code verify             # Verify code against AC
/sdlc-studio code check              # Run linters and checks
/sdlc-studio tsd                      # Create test strategy document
/sdlc-studio test-spec               # Generate test specifications
/sdlc-studio test-automation         # Generate executable tests
/sdlc-studio story plan              # Preview story workflow
/sdlc-studio story implement         # Execute story workflow (all phases)
/sdlc-studio epic plan               # Preview epic workflow (all stories)
/sdlc-studio epic implement          # Execute epic workflow (all stories)
```

## Get Help for Any Type

```bash
/sdlc-studio {type} help             # Show help for specific type
```

Examples:

```bash
/sdlc-studio prd help                # PRD commands and options
/sdlc-studio epic help               # Epic generation help
/sdlc-studio bug help                # Bug tracking help
/sdlc-studio code help               # Code plan/test/verify/check help
/sdlc-studio test-spec help          # Test specification help
/sdlc-studio test-automation help    # Test automation help
```

Each help page shows:

- Available actions and what they do
- Prerequisites
- Output format and location
- Examples
- Next steps

## Instructions

When invoked with `/sdlc-studio [type] [action]`:

1. **Parse Command:** Extract type and action from arguments
2. **Load Help File:** Read `help/{type}.md` for command-specific guidance
3. **Check Philosophy:** If generate mode, load `reference-philosophy.md#generate-mode` FIRST
4. **Follow Progressive Loading:**
   - Load reference files only for multi-step workflows
   - Load templates only when creating artifacts
   - Load decision files when choosing approaches (TDD, Ready status)
5. **Execute Workflow:** Follow step-by-step procedure in reference file
6. **Update Status:** Modify artifact status markers per `reference-outputs.md`
7. **Validate:** Check Ready criteria in `reference-decisions.md` before proceeding

See "Progressive Loading Guide" below for detailed file loading patterns.

## Progressive Loading Guide

## Error Handling

**Missing prerequisites:** Prompts to run earlier pipeline step (e.g., no PRD → `prd`, no epics → `epic`, no stories → `story`, no plans → `code plan`). **Existing files:** Warns and asks to continue unless `--force`. **No type:** Asks user which type. **ID collision:** Auto-increments. **Open questions:** Reports and pauses. **Unknown language:** Asks user to specify framework.

## Typical Workflow

### Greenfield (Create Mode)

```text

PRD → TRD → Personas → Epics → Stories
                                  │
                    ┌─────────────┴─────────────┐
                    │                           │
              TDD Path                    Test-After Path
              (test-first)                (code-first)
                    │                           │
              test-spec                    code plan
                    │                           │
              code plan                   code implement
                    │                           │
         code implement --tdd              test-spec
                    │                           │
              code verify                 test-automation
                    │                           │
              code test                     code verify
                                                │
                                            code test
```

**Per-story choice:** You choose TDD or Test-After for each story, not globally. Both paths produce the same artifacts, just in different order.

### Automated Workflow (Recommended)

For streamlined development, use workflow automation:

```text

PRD → TRD → Personas → Epics → Stories
                                  │
                          story plan --story US0001
                                  │
                          story implement --story US0001
                                  │
                          (all 7 phases run automatically)
```

Or at the epic level:

```text

PRD → TRD → Personas → Epics → Stories
                                  │
                          epic plan --epic EP0001
                                  │
                          epic implement --epic EP0001
                                  │
                          (all stories processed in dependency order)
```

**Workflow phases per story:**

1. Plan (code plan)
2. Test Spec (test-spec)
3. Tests (test-automation)
4. Implement (code implement)
5. Test (code test)
6. Verify (code verify)
7. Check (code check)
8. Review (status review)

### Brownfield (Specification Extraction)

```bash

prd generate → trd generate → persona generate → epic → story generate → test-spec → test-automation → code test (VALIDATE)
```

**Critical:** The `code test` step validates specs against reality. Not optional.

### Development Cycle

```text

code plan → code implement → code test → code verify → code check
```

Status: `Draft/Ready → Planned → In Progress → Review → Done`

### Daily Usage

```bash

/sdlc-studio status          # Visual dashboard - what needs attention?
/sdlc-studio status --brief  # Quick: Requirements 85% | Code 90% | Tests 94%
/sdlc-studio hint            # Single next step
/sdlc-studio code plan       # Plan next story
/sdlc-studio code implement  # Execute plan
```
