# Task: [RELS.1001]: Domain Setup and Directory Structure

## Status
- [x] **Task completed** - acceptance criteria met
- [x] **Tests pass** - tests executed and passing (or N/A if no tests)
- [x] **Verified** - by the verify-task agent

**Note on "Tests pass"**:
- If tests were created/modified, you MUST run them and show output
- "Tests pass" means tests were EXECUTED and all passed
- "Tests pass - N/A" is only valid for documentation-only tickets
- Test file existence alone does NOT satisfy this requirement

## Summary
Create the relationships domain directory structure and registration pattern following the existing codebase patterns for domains like tables, fields, and records.

## Background
This is the foundation task for the relationship management feature. The MCP Quickbase server organizes tools into domain-specific directories (apps, tables, fields, records, etc.). This task establishes the relationships domain structure and registration pattern that all subsequent relationship tools will use.

This implements Phase 1 foundation work from plan.md.

## Acceptance Criteria
- [x] Directory `src/tools/relationships/` exists
- [x] File `src/tools/relationships/index.ts` exists with `registerRelationshipTools()` function
- [x] Registration function accepts `QuickbaseClient` parameter
- [x] Registration pattern follows existing domain patterns (see `src/tools/fields/index.ts` or `src/tools/tables/index.ts`)
- [x] Exports are structured for future tool additions
- [x] File structure validated by TypeScript compilation (`npm run build` succeeds)

## Technical Requirements
- Follow existing domain registration pattern from other tool directories
- Use TypeScript with strict type checking
- Export a `registerRelationshipTools(client: QuickbaseClient)` function
- Prepare for 4 tools: get_relationships, create_relationship, update_relationship, delete_relationship
- No actual tool implementations yet - this is structure only

## Implementation Notes
Study existing patterns:
- `src/tools/fields/index.ts` - Shows registration pattern with toolRegistry
- `src/tools/tables/index.ts` - Shows how to organize domain exports

Pattern to follow:
```typescript
import { QuickbaseClient } from '../../client/quickbase';
import { toolRegistry } from '../registry';

export function registerRelationshipTools(client: QuickbaseClient): void {
  // Tools will be registered here in subsequent tasks
}

// Future exports
// export { GetRelationshipsTool } from './get_relationships';
// export { CreateRelationshipTool } from './create_relationship';
// export { UpdateRelationshipTool } from './update_relationship';
// export { DeleteRelationshipTool } from './delete_relationship';
```

## Dependencies
- None - this is the first task in the sequence
- Existing infrastructure: BaseTool, QuickbaseClient, toolRegistry

## Risk Assessment
- **Risk**: Directory structure doesn't match existing patterns
  - **Mitigation**: Study at least 2 existing domain directories before implementing
- **Risk**: Registration function signature incompatible with main tools/index.ts
  - **Mitigation**: Review how other domains are registered in src/tools/index.ts

## Files/Packages Affected
- src/tools/relationships/ (new directory)
- src/tools/relationships/index.ts (new file)

## Deliverables Produced

Documents created in `deliverables/` directory:

- None

## Verification Notes
Verify-task agent should confirm:
- Directory structure matches existing domain patterns
- index.ts compiles without errors
- Registration function signature is correct
- No actual tools registered yet (that happens in subsequent tasks)
- Code follows existing naming conventions (snake_case for tools, camelCase for functions)
