flext-architecture-layers

The flext-architecture-layers Skill enforces layer boundaries by utilizing AST-based static analysis to validate import directions, preventing subprojects from importing private modules and ensuring strict L3 -> L2 -> L1 -> L0 layering.

Subproject imports fail checks when they violate dependency direction contracts by importing private flext_core modules. AST-based static analysis flags these disallowed imports to prevent unintended dependencies and maintain architectural integrity.

The best way to prevent unintended dependencies in a layered architecture is defining strict dependency rules between layers and automatically validating imports using AST-based static analysis to flag disallowed cross-layer access.

To check flext-core architecture layer compliance, run a command like `make check PROJECT=flext-core` to verify that all subproject imports adhere to the established L3 -> L2 -> L1 -> L0 dependency direction contracts.

AST-based static analysis works for validating Python import contracts by precisely parsing the abstract syntax tree to detect and flag disallowed imports from private modules before runtime execution.
