# Implementation Plan: 012-remove-superset-tool

**Branch**: `012-remove-superset-tool` | **Date**: 2026-01-22 | **Spec**: [spec.md](specs/012-remove-superset-tool/spec.md)

## Summary

The primary requirement is to refactor the backend by removing the redundant `superset_tool` module and merging its essential logic into the `backend` package. This involves migrating the `SupersetClient` logic, utility modules, and configuration models while deprecating CLI-specific interactive logic.

## Technical Context

**Language/Version**: Python 3.9+  
**Primary Dependencies**: FastAPI, Pydantic, requests, pyyaml (migrated from superset_tool)  
**Storage**: SQLite (tasks.db, migrations.db), Filesystem  
**Testing**: pytest  
**Target Platform**: Linux server  
**Project Type**: Web application (FastAPI backend + SvelteKit frontend)  
**Performance Goals**: N/A (Cleanup task)  
**Constraints**: Zero references to `superset_tool` in `backend/` source code.  
**Scale/Scope**: Refactoring core backend infrastructure.

## Constitution Check

*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*

1. **Semantic Protocol Compliance**: All migrated code must use `[DEF]` anchors and `@RELATION` tags as per `semantic_protocol.md`.
2. **Causal Validity**: Contracts (Pydantic models and API surfaces) must be defined before implementation.
3. **Everything is a Plugin**: Ensure that logic previously in `superset_tool` that acts as a tool or extension is integrated within the backend's plugin architecture if applicable.
4. **Fractal Complexity Limit**: Migrated modules must adhere to complexity limits.

```

**Structure Decision**: Web application structure. The `superset_tool` logic will be absorbed into `backend/src/core/` and its subdirectories.
