SDD Init Skill

Initialize Spec-Driven Development (SDD) in the current project. Detects tech stack, conventions, architecture patterns, and bootstraps all persistence backends (Constitution + Knowledge Graph).

When to Use

Trigger phrases:

"sdd-init", "init sdd", "setup sdd"
"initialize sdd", "setup project", "initialize project context"
"bootstrap sdd", "start sdd"
"detect project stack", "detect tech stack"

Workflow

1. Detect Project Context
   ├── Scan tech stack (languages, frameworks, tools)
   ├── Identify conventions (folder structure, patterns, configs)
   └── Detect architecture (monolith, microservices, serverless)

2. Bootstrap Constitution
   ├── Check if docs/specs/architecture.md exists
   ├── If missing → ask user to create with constitution skill
   └── If exists → show current state

3. Bootstrap Knowledge Graph
   ├── Check if docs/specs/knowledge-graph.json exists
   ├── Create with initial discoveries (stack, patterns, conventions)
   └── Link to Constitution

4. Return Structured Result
   └── status, executive_summary, artifacts, next_recommended

Phase 1: Detect Project Context

1.1 Scan Tech Stack
