Design Gate

A design gate checker for architecture validation, feasibility analysis, and impact scope assessment.

Design Gate Skill

Overview

A generic design gate checker that validates architecture reasonableness, technical feasibility, and impact scope assessment for a design before implementation proceeds.

Key Features

• Architecture Validation: Checks components, responsibilities, interfaces, dependencies, and structure.
• Feasibility Analysis: Validates tech stack (language, framework, database, external deps).
• Impact Scope Assessment: Validates affected modules, breaking changes, migration needs, and risk level.
• Composite Gate: Runs all checks together and produces an overall pass/fail decision.
• Score-based: Each check returns a 0-100 score with details and issues; configurable pass threshold.
• Persistence: All models serialize to/from JSON for storage and reload.

Use Cases

• Design phase gate review before development.
• Architecture review for new features or refactors.
• Migration risk assessment.
• Standardizing design documentation completeness.

Installation

bash

clawhub install design-gate

Usage

Basic Usage

python

from src import DesignGate, Design, Component, TechStack, ImpactScope

gate = DesignGate()

design = Design(
    title="User Service",
    description="User management microservice",
    components=[
        Component("UserController", "Handle HTTP", ["GET", "POST"]),
        Component("UserRepo", "Persist users", ["save", "find"]),
    ],
    dependencies=["auth-service"],
    tech_stack=TechStack("python", "django", "postgres", ["redis"]),
    impact_scope=ImpactScope(["user-module"], False, False, "medium"),
)

results = gate.run_all_checks(design)
print(gate.overall_pass(results))  # True if all checks pass

Individual Checks

python

arch_result = gate.check_architecture(design)
feasibility_result = gate.check_feasibility(design.tech_stack)
impact_result = gate.check_impact_scope(design.impact_scope)

Custom Threshold

python

strict_gate = DesignGate(pass_threshold=80.0)

API Reference

• check_architecture(design: Design) -> GateResult
• check_feasibility(tech_stack: TechStack) -> GateResult
• check_impact_scope(impact: ImpactScope) -> GateResult
• run_all_checks(design: Design) -> List[GateResult]
• overall_pass(results: List[GateResult]) -> bool

Models

• Design: title, description, components, dependencies, tech_stack, impact_scope
• Component: name, responsibility, interfaces
• TechStack: language, framework, database, external_deps
• ImpactScope: affected_modules, breaking_changes, migration_needed, risk_level
• GateResult: check_name, passed, score, message, details
