**Date**: 2026-01-09
**Phase Completed**: Phase 0 & Phase 1 (Schema & Storage Layer)
**Status**: ā
Ready for Phase 2 (API Layer & Endpoints)
---
## š What Was Accomplished
### Phase 0: Research & Planning ā
COMPLETE

- Documented file format (YAML frontmatter + Markdown)
- Mapped category structure
- ā
Reviewed mcp-project-orchestrator repository
- Identified hexagonal architecture patterns
- Documented template system
- Analyzed integration points
#### 2. Architecture Decisions
- ā
**Decision 1**: Use unified Prompt table with `promptType` discriminator

**Decision 2**: Separate table for execution records
- ā
**Decision 3**: Use `/v1/` prefix for new API endpoints
#### 3. Documentation Created
- ā

### Phase 1: Schema & Storage Layer ā
COMPLETE
#### 1. Extended Prompt Entity
**File**: `src/core/entities/prompt.entity.ts`
**New Types Added**:
```typescript
export type PromptType =
| 'standard'
| 'subagent_registry'
| 'main_agent_template'
| 'project_orchestration_template';
export type ClaudeModel =
| 'claude-opus'
| 'claude-sonnet'
| 'claude-haiku';
export interface AgentConfig {
model?: ClaudeModel;
systemPrompt?: string;
tools?: string[];
mcpServers?: string[];
subagents?: string[];
compatibleWith?: string[];
sourceUrl?: string;
executionCount?: number;
successRate?: number;
lastExecutedAt?: Date;
}
```
**New Helper Methods**:
- `isSubagent()`: Check if prompt is a subagent
- `isMainAgent()`: Check if prompt is a main agent template
- `isProjectTemplate()`: Check if prompt is a project orchestration template
- `getModel()`: Get the Claude model for this agent
- `getSystemPrompt()`: Get the system prompt for this agent
#### 2. Database Migrations Created
**Location**: `data/migrations/`
**Files**:
1. `000_migration_tracking.sql` - Migration history table
2. `001_add_agent_fields_to_prompts.sql` - Extends prompts table
3. `002_create_agent_execution_records.sql` - New execution tracking table
4. `README.md` - Comprehensive migration documentation
**Schema Changes**:
- **11 new columns** added to prompts table
- **10+ indexes** created for query performance
- **2 constraints** added for data integrity
- **1 new table** created (agent_execution_records)
#### 3. VoltAgent Subagents Imported
**Script**: `scripts/import-voltAgent-subagents.ts`
**Results**:
- ā
**127/127 subagents imported successfully** (100% success rate)
- ā
**0 errors** during import
- ā
**10 categories** organized:
- dev: 10 subagents
- language: 26 subagents
- infra: 14 subagents
- quality: 14 subagents
- data: 12 subagents
- dx: 13 subagents
- specialized: 12 subagents
- business: 11 subagents
- meta: 9 subagents
- research: 6 subagents
**Output**:
- 127 JSON files in `data/prompts/subagents/`
- 1 index file at `data/prompts/subagents/index.json`
#### 4. Extended Repository Interface
**File**: `src/core/ports/prompt-repository.interface.ts`
**New Interface Methods**:
```typescript
// Type filtering
findByType(type: PromptType, limit?: number): Promise<Prompt[]>;
// Subagent operations
findSubagents(filter?: SubagentFilter, limit?: number): Promise<Prompt[]>;
findMainAgents(projectType?: string, limit?: number): Promise<Prompt[]>;
findProjectTemplates(limit?: number): Promise<Prompt[]>;
// Metadata queries
getSubagentCategories(): Promise<string[]>;
getAgentModels(): Promise<ClaudeModel[]>;
// Execution tracking
updateExecutionStats(
id: string,
executionCount: number,
successRate: number,
lastExecutedAt: Date
): Promise<void>;
```
#### 5. Implemented File Storage Adapter
**File**: `src/adapters/file/file-prompt-repository.ts`
**New Methods Implemented**:
- ā
`findByType()` - Filter prompts by type
- ā
`findSubagents()` - Find subagents with advanced filtering
- ā
`findMainAgents()` - Find main agent templates
- ā
`findProjectTemplates()` - Find project orchestration templates
- ā
`getSubagentCategories()` - Get all categories
- ā
`getAgentModels()` - Get all models used
- ā
`updateExecutionStats()` - Update execution metrics
- ā
`scanDirectory()` - Recursive directory scanning for nested files
**Improvements**:
- Enhanced `findLatestVersions()` to recursively scan subdirectories
- Added support for both `template` and `system_prompt` fields
- Backward compatible with existing prompt files
- Handles malformed data gracefully

- `get_subagent(id)` - Fetch subagent definition
- `get_main_agent_template(projectType)` - Get main agent config
- `list_project_templates()` - List available templates
#### 4. Add OpenAPI Documentation

- Add examples for each endpoint
#### 5. Create Validation Schemas
- Use Zod for request validation

## š§ Technical Decisions Summary
### 1. Unified Prompt Table
**Rationale**: Single table with discriminator maintains backward compatibility and simplifies API surface.
### 2. AgentConfig as Nested Object
**Rationale**: Optional configuration object allows flexible extension without polluting main entity.
### 3. File-Based Storage First
**Rationale**: Start with file storage for simplicity, migrate to PostgreSQL later.
### 4. Model Selection Strategy
- **Haiku**: Fast, cheap tasks (exploration, scanning)
- **Sonnet**: Most development work (analysis, review)
- **Opus**: Complex orchestration (main agents, architects)
### 5. Execution Tracking in Separate Table
**Rationale**: Keeps prompt definitions immutable, enables analytics without modifying prompts.
