Intract is an intent-contract layer for codebases and software delivery artifacts.

It lets you describe, validate and monitor intent across:

code
functions
classes
files
project manifests
API endpoints
Dockerfiles
CI/CD workflows
Kubernetes manifests
DevOps artifacts

Intract is not primarily a programming language. It is a contract system for short, portable intent declarations.

Quick example

# @intract.v1 scope:function intent:validate:user_permission priority:1 domain:security input:user,resource output:allowed effect:none forbid:write,network validate:input_presence,return_value,no_forbidden_effect meaning:"check whether user can modify resource without changing state"
def can_update_resource(user, resource):
    return user.is_admin or resource.owner_id == user.id

Run:

python -m intract scan .
python -m intract validate .
