**Scope**: 4-6 hours
**Phase 2 Deliverables**:
- src/tools/relationships/create_relationship.ts tool implementation
- src/tools/relationships/update_relationship.ts tool implementation
- Extended tests in src/__tests__/tools/relationships.test.ts
## Phase 3: Destructive Operations with Safety Measures
### RELS.3001 - Implement DeleteRelationshipTool with Safety Warnings
**File**: `RELS.3001_delete-relationship-tool.md`
**Primary Agent**: implement-feature
**Summary**: Implement delete_relationship tool with comprehensive safety warnings and agent guidance to prevent unintended data loss.
**Dependencies**: RELS.1001, RELS.1002, RELS.2001, RELS.2002
**Scope**: 4-5 hours
**Phase 3 Deliverables**:
- src/tools/relationships/delete_relationship.ts tool implementation
- Complete test coverage for delete scenarios
- Final documentation updates
## Phase 4: Integration and Verification
### RELS.4001 - Integration Testing and Coverage Verification
**File**: `RELS.4001_integration-testing.md`
**Primary Agent**: verify-task
**Summary**: Run comprehensive integration tests to verify all relationship tools are properly registered, execute correctly, and meet coverage thresholds.
**Dependencies**: All previous tasks (RELS.1001-RELS.3001)
**Scope**: 2-3 hours
### RELS.4002 - Final Verification and Documentation Review
**File**: `RELS.4002_final-verification.md`
**Primary Agent**: verify-task
**Summary**: Perform final verification of all relationship tools, review tool descriptions for agent clarity, and confirm all success metrics.
**Dependencies**: RELS.4001
**Scope**: 1-2 hours
**Phase 4 Deliverables**:
- Passing test suite with coverage >= 40% (lines/functions/statements) and >= 20% branches
- All linting checks pass
- Verified tool descriptions for agent safety

## Critical Path
The critical path for implementation is:
1. RELS.1001 (Foundation) → 2-3 hours
2. RELS.1002 (Read tool) → 4-6 hours
3. RELS.1003 (Registration) → 1-2 hours
4. RELS.2001 (Create tool) → 5-7 hours
5. RELS.2002 (Update tool) → 4-6 hours
6. RELS.3001 (Delete tool) → 4-5 hours
7. RELS.4001 (Integration) → 2-3 hours
8. RELS.4002 (Final verification) → 1-2 hours
**Total Estimated Time**: 23-34 hours
## Success Metrics
All tasks contribute to these success metrics from plan.md:
- [ ] All four relationship tools implemented and registered
- [ ] get_relationships returns accurate relationship data
- [ ] create_relationship successfully creates relationships with lookup/summary fields
- [ ] update_relationship adds fields without deleting existing ones
- [ ] delete_relationship has prominent destructive operation warnings
- [ ] Test coverage >= 40% lines/functions/statements, >= 20% branches
- [ ] No lint errors
- [ ] Tool descriptions help agents understand when to use each tool
- [ ] Destructive operations clearly marked and explain consequences
## Quality Gates
Before proceeding to next phase, verify:
**After Phase 1**:
- get_relationships tool functional and tested
- API response structure validated
- Tools registered in main index
**After Phase 2**:
- create_relationship and update_relationship functional
- JSON Schema conditional validation working
- ADDITIVE ONLY behavior verified for update
**After Phase 3**:
- delete_relationship implemented with safety warnings
- All warning requirements met (see RELS.3001)
- All four tools functional
**After Phase 4**:
- All tests pass
- Coverage thresholds met
- All success metrics satisfied
- Ready for commit
## Notes
- Each task is scoped to 2-8 hours of work
- All tasks include comprehensive test requirements
- Safety verification is critical for delete operation (RELS.3001)
- Phase 4 tasks are verification-focused, not implementation
- Parameter naming follows snake_case convention throughout
- Tool descriptions are designed for AI agent consumption
