• Event Modeling: Design event-sourced systems (Martin Dilger's methodology)
• Architecture Decision Records: Document and manage architectural decisions
• GitHub Integration: Project boards, issues, PRs, review handling
• Memory Protocol: Persistent knowledge using Memento MCP

Commands

Command	Description
/sdlc:setup	Initialize project configuration and install gh extensions
/sdlc:work	Start or continue working on an issue
/sdlc:pr	Create/update PR with mutation testing
/sdlc:review	Handle PR review feedback (reply in-thread)
/sdlc:design	Design event model workflows
/sdlc:adr	Create and manage architecture decisions

Agents

TDD Agents (strict file boundaries enforced via hooks):

• sdlc:red - Write failing tests (test files only)
• sdlc:green - Make tests pass (production code only)
• sdlc:domain - Create type definitions (signatures only)
• sdlc:mutation - Run mutation testing

Review Agents:

• sdlc:story - Business value perspective
• sdlc:architect - Technical feasibility (ARCHITECTURE.md only)
• sdlc:ux - UX/accessibility perspective
• sdlc:code-reviewer - Three-stage code review

Event Modeling Agents (event model files only):

• sdlc:discovery - Domain discovery
• sdlc:workflow-designer - Design workflows with 9-step process
• sdlc:gwt - Generate Given/When/Then scenarios
• sdlc:model-checker - Validate event model completeness

Architecture Agents:

• sdlc:adr - Write architecture decision records (ADRs only)
• sdlc:design-facilitator - Guide architecture decisions

Utility Agent:

• sdlc:file-updater - Config, scripts, general docs (blocked from specialized files)

Development Modes

Event Modeling (for applications):

• Workflow → Vertical Slice → Component → Subtask hierarchy
• GWT scenarios as acceptance criteria
• Full event sourcing methodology

Traditional (for libraries/utilities):

• Feature → Subtask hierarchy
• Architecture documentation focus
