Project Structure

Directory layout implementing the AgentOS 3-layer context model.

3-Layer Directory Structure

Copyproject/
├── docs/
│   ├── standards/        # Layer 1: How you build
│   ├── product/          # Layer 2: What and why
│   └── spec/             # Layer 3: What to build next

AgentOS 3-Layer Model:

• Layer 1 (standards/): Technical patterns, coding principles, architecture decisions
• Layer 2 (product/): Product vision, roadmap, business context
• Layer 3 (spec/): Feature specs and change proposals

Layer 1: Standards (docs/standards/)

Technical standards adapted for the project's technology stack:

• coding.md - TDD patterns (Stub → Test → Implement → Refactor), coding principles
• architecture.md - Layered architecture (Router → Service → Repository → Entity → Database)

Layer 2: Product (docs/product/)

Product-level documentation:

• product.md - Product definition, target users, core features, success metrics
• roadmap.md - Next 3 features in priority order, implementation strategy, current status

Layer 3: Specs (docs/spec/)

Greenfield Features (New Code)

Copydocs/spec/<feature>/
└── spec.md          # Unified requirements + technical design

spec.md contains:

• Requirements (user stories, acceptance criteria, business rules)
• Technical Design (data models, API design, component structure)

Brownfield Changes (Existing Code)

Copydocs/changes/<feature>/<change>/
├── proposal.md      # Change proposal
├── delta.md         # ADDED/MODIFIED/REMOVED changes
└── tasks.md         # Implementation tasks

Workflow:

1. /spec:propose creates proposal.md and delta.md
2. /spec:work executes implementation
3. /spec:complete merges delta into spec.md, deletes change folder

Beads Task Tracking

Copy.beads/
├── beads.jsonl      # Git-tracked task data
├── beads.db         # Local cache (gitignored)
└── bd.sock          # Socket (gitignored)

.gitignore entries:

Copy.beads/beads.db
.beads/bd.sock

Beads provides dependency-aware task management. Commands like /spec:create and /spec:propose automatically create epics with tasks ordered by technical dependencies (Entity → Repository → Service → Router).
