software implementation

What it does

Implements tasks from SPEC.md through a plan-and-execute workflow with verification and failure backpropagation.

When to use it

Use when asked to build or implement a specification or one of its tasks.

Give it a project containing SPEC.md; it implements and verifies the chosen tasks, updating their code and status.

What you provide

No additional actions listed in the analysis.

Delegates to the backprop skill after a failed verification instead of retrying blindly.

Delegates specification corrections and unspecified edge cases to the spec skill before resuming the build.
