Why it matters
Small tools are easy to create but often abandoned when deployment ownership and maintenance remain implicit.
Scope
A stable concept used by Service Cards, deployment contracts and the SmallGreen Spec.
Out of scope
It is not a guarantee of security, permanence or universal compatibility.
How it works
Bound the purpose declare the resource budget publish the deployment contract and keep a tested exit path.
Example
A URL shortener with one deployment contract one evidence trail and a complete teardown path is Small Software.
