Metadata

  • Commit Message: refactor(cli): remove direct sqlalchemy import from system command module
  • Branch: refactor/cli-system-remove-sqlalchemy-import

Background and Context

The cleveragents.cli.commands.system module directly imports sqlalchemy. This is a violation of the layered architecture, where the CLI layer should not directly interact with the database layer. All database interactions must go through the application service layer, which acts as the boundary between the CLI and infrastructure concerns.

File: src/cleveragents/cli/commands/system.py

This coupling was detected automatically by the Architecture Guard supervisor agent scanning for cross-layer import violations.


Expected Behavior

The cleveragents.cli.commands.system module should have no direct dependency on sqlalchemy. Any database-related errors or operations surfaced in the CLI should be handled by catching application-layer exceptions, not by importing or referencing SQLAlchemy types directly.


Acceptance Criteria

  • src/cleveragents/cli/commands/system.py contains no import sqlalchemy or from sqlalchemy statements
  • Any database error handling in the system command is done via application-layer exception types (not SQLAlchemy exceptions directly)
  • All existing tests for cleveragents.cli.commands.system continue to pass
  • No new direct sqlalchemy imports are introduced in any other CLI module as a side-effect of this change
  • nox passes with coverage >= 97%

Subtasks

  • Identify all usages of sqlalchemy within src/cleveragents/cli/commands/system.py
  • Determine which application-layer service(s) or exception types should replace the direct SQLAlchemy references
  • Refactor the system command to delegate database error handling to the application layer
  • Update or add unit tests to cover the refactored error-handling paths
  • Verify no other CLI modules have been inadvertently affected
  • Run full test suite and confirm coverage >= 97%

Definition of Done

This issue should be closed when:

  1. The direct sqlalchemy import has been removed from src/cleveragents/cli/commands/system.py
  2. Database error handling flows through the application service layer
  3. All tests pass and coverage remains >= 97%
  4. A PR has been merged to master referencing this issue

[AUTO-ARCH] Architecture Supervisor Review

This violation has been reviewed by the Architecture Supervisor (Cycle 1).

Violation Classification

  • Type: Cross-layer import (CLI → Infrastructure)
  • Severity: High — violates the core Layered Architecture principle (ADR-001 through ADR-048 all assume this boundary)
  • Layer boundary breached: cleveragents.cli.commands (CLI layer) → sqlalchemy (Infrastructure/ORM layer)

Architectural Guidance

The CLI layer must never import infrastructure concerns directly. The correct pattern is:

CLI layer
  └── calls Application Service (e.g., SystemService.get_status())
        └── Application Service catches SQLAlchemy exceptions
              └── re-raises as domain exceptions (e.g., DatabaseUnavailableError)
CLI layer catches domain exceptions only

Specifically:

  1. Any sqlalchemy.exc.* exception handling in system.py must be replaced with application-layer exception types
  2. Any SQLAlchemy type annotations (e.g., Session) must be removed from the CLI module
  3. The application service layer must expose a clean interface that hides all ORM details

ADR Reference

This violation is addressed by the layered architecture principle established across the codebase. Worker [AUTO-ARCH-4] has been dispatched to author ADR-049: Layered Architecture Boundary Enforcement Policy which will formally codify this boundary and provide a detection/remediation checklist.

Next Steps

  • Implementer: Fix src/cleveragents/cli/commands/system.py per acceptance criteria above
  • AUTO-ARCH-4: Author ADR-049 to formally document this boundary rule
  • Architecture Guard: Continue scanning for similar violations in other CLI modules
