feat(#66): implement tag filtering in search API endpoint
Add support for filtering search results by tags in the main search endpoint. Changes: - Add tags parameter to SearchQueryDto (comma-separated tag slugs) - Implement tag filtering in SearchService.search() method - Update SQL query to join with knowledge_entry_tags when tags provided - Entries must have ALL specified tags (AND logic) - Add tests for tag filtering (2 controller tests, 2 service tests) - Update endpoint documentation - Fix non-null assertion linting error The search endpoint now supports: - Full-text search with ranking (ts_rank) - Snippet generation with highlighting (ts_headline) - Status filtering - Tag filtering (new) - Pagination Example: GET /api/knowledge/search?q=api&tags=documentation,tutorial All tests pass (25 total), type checking passes, linting passes.

# ORCH-105 Implementation Summary
|
||||
|
||||
## Overview
|
||||
|
||||
Successfully implemented the agent spawner service using the Claude SDK for the orchestrator application. This is Phase 2 of the M6-AgentOrchestration milestone.
|
||||
|
||||
## Deliverables
|
||||
|
||||
### 1. Type Definitions
|
||||
|
||||
**File:** `/home/localadmin/src/mosaic-stack/apps/orchestrator/src/spawner/types/agent-spawner.types.ts`
|
||||
|
||||
Defined comprehensive TypeScript interfaces:
|
||||
|
||||
- `AgentType`: "worker" | "reviewer" | "tester"
|
||||
- `AgentState`: "spawning" | "running" | "completed" | "failed" | "killed"
|
||||
- `AgentContext`: Repository, branch, work items, and optional skills
|
||||
- `SpawnAgentRequest`: Complete request payload with options
|
||||
- `SpawnAgentResponse`: Response with agentId and state
|
||||
- `AgentSession`: Internal session tracking metadata
|
||||
|
||||
### 2. Agent Spawner Service
|
||||
|
||||
**File:** `/home/localadmin/src/mosaic-stack/apps/orchestrator/src/spawner/agent-spawner.service.ts`
|
||||
|
||||
Features:
|
||||
|
||||
- NestJS Injectable service with dependency injection
|
||||
- Claude SDK initialization from ConfigService
|
||||
- Validation of API key on startup (throws if missing)
|
||||
- UUID-based unique agent ID generation
|
||||
- In-memory session storage using Map
|
||||
- Comprehensive input validation
|
||||
- Logging via NestJS Logger
|
||||
|
||||
Methods:
|
||||
|
||||
- `spawnAgent(request)`: Creates and tracks a new agent
|
||||
- `getAgentSession(agentId)`: Retrieves session by ID
|
||||
- `listAgentSessions()`: Lists all active sessions
|
||||
- `validateSpawnRequest(request)`: Private validation helper
|
||||
|
||||
### 3. Comprehensive Tests
|
||||
|
||||
**File:** `/home/localadmin/src/mosaic-stack/apps/orchestrator/src/spawner/agent-spawner.service.spec.ts`
|
||||
|
||||
Test Coverage: **100%** (18 tests, all passing)
|
||||
|
||||
Test Categories:
|
||||
|
||||
- Constructor initialization (3 tests)
|
||||
- Service instantiation
|
||||
- API key loading
|
||||
- Error on missing API key
|
||||
- Agent spawning (11 tests)
|
||||
- Basic spawning
|
||||
- Unique ID generation
|
||||
- Session tracking
|
||||
- All validation paths (taskId, agentType, repository, branch, workItems)
|
||||
- Optional parameters (skills, options)
|
||||
- Error handling
|
||||
- Session management (4 tests)
|
||||
- Get non-existent session
|
||||
- Get existing session
|
||||
- List empty sessions
|
||||
- List multiple sessions
|
||||
|
||||
### 4. Module Configuration
|
||||
|
||||
**File:** `/home/localadmin/src/mosaic-stack/apps/orchestrator/src/spawner/spawner.module.ts`
|
||||
|
||||
- Registered `AgentSpawnerService` as provider
|
||||
- Exported for use in other modules
|
||||
|
||||
### 5. Barrel Export
|
||||
|
||||
**File:** `/home/localadmin/src/mosaic-stack/apps/orchestrator/src/spawner/index.ts`
|
||||
|
||||
- Clean exports for service, module, and types
|
||||
|
||||
### 6. Configuration Updates
|
||||
|
||||
**File:** `/home/localadmin/src/mosaic-stack/apps/orchestrator/vitest.config.ts`
|
||||
|
||||
- Added coverage configuration
|
||||
- Set thresholds to 85% for lines, functions, branches, statements
|
||||
- Configured V8 coverage provider
|
||||
|
||||
## TDD Workflow
|
||||
|
||||
Followed strict Test-Driven Development:
|
||||
|
||||
1. **RED Phase**: Created 18 failing tests
|
||||
2. **GREEN Phase**: Implemented minimum code to pass all tests
|
||||
3. **REFACTOR Phase**: Cleaned up code, fixed linting issues
|
||||
|
||||
## Quality Checks
|
||||
|
||||
All checks passing:
|
||||
|
||||
- ✅ **Tests**: 18/18 passing (100% coverage)
|
||||
- ✅ **Type Checking**: No TypeScript errors
|
||||
- ✅ **Linting**: No ESLint errors
|
||||
- ✅ **Build**: Successful compilation
|
||||
- ✅ **Integration**: Module properly registered
|
||||
|
||||
## Technical Decisions
|
||||
|
||||
1. **In-memory storage**: Using Map for Phase 2; will migrate to Valkey in ORCH-107
|
||||
2. **Synchronous spawning**: Kept method synchronous for now; will add async Claude SDK calls later
|
||||
3. **Early validation**: All input validated before processing
|
||||
4. **UUID for IDs**: Using crypto.randomUUID() for guaranteed uniqueness
|
||||
5. **Configuration-driven**: API key loaded from environment via ConfigService
|
||||
|
||||
## Future Work
|
||||
|
||||
Items for subsequent issues:
|
||||
|
||||
- ORCH-106: Docker sandbox isolation
|
||||
- ORCH-107: Migrate to Valkey for session persistence
|
||||
- Implement actual Claude SDK message/conversation creation
|
||||
- Add retry logic for API failures
|
||||
- Add timeout handling
|
||||
- Add agent state transitions (spawning → running → completed/failed)
|
||||

||||
