Allium

Allium is a formal language for capturing software behaviour at the domain level. It sits between informal feature descriptions and implementation, providing a precise way to specify what software does without prescribing how it's built.

The name comes from the botanical family containing onions and shallots, continuing a tradition in behaviour specification tooling established by Cucumber and Gherkin.

Key principles:

Describes observable behaviour, not implementation

Captures domain logic that matters at the behavioural level

Generates integration and end-to-end tests (not unit tests)

Forces ambiguities into the open before implementation

Implementation-agnostic: the same spec could be implemented in any language

Allium does NOT specify programming language or framework choices, database schemas or storage mechanisms, API designs or UI layouts, or internal algorithms (unless they are domain-level concerns).
