Decomplect-Py

Architectural analysis for Python design quality.

Usage

/decomplect-py                # Run all 3 analyzers in parallel
/decomplect-py --simplicity   # Specific analyzer
/decomplect-py --fcis         # Specific analyzer
/decomplect-py --coupling     # Specific analyzer

Analyzers

Analyzer Question
simplicity-analyzer Is this truly simple or just easy?
fcis-analyzer Is pure logic separated from I/O?
coupling-analyzer Are modules well-separated?

What It Checks

Pillar Focus
Simplicity Values over state, decomplected concerns
FCIS Functional core (pure), imperative shell (I/O)
Coupling High cohesion, low coupling

When to Use

  • Reviewing Python system design
  • Before major refactoring
  • Assessing architectural quality
  • Checking if code is "Rich Hickey approved"

Supported Languages

  • Python (.py files only)

Python-Specific Patterns

  • dataclasses(frozen=True) and NamedTuple for immutable values
  • Mutable default argument anti-patterns
  • Django/Flask view architecture
  • Circular import detection
  • Module-level state analysis
