Follow Dave Farley's Acceptance Test-Driven Development (ATDD) approach using his ATDD skill. Before writing any code, invoke the msec:atdd-build skill with the Skill tool, with the arguments "Specify and build the system described in TASK.md: write executable acceptance tests for its requirements first, then implement until they pass". Follow that skill's build workflow — spec first in the language of the problem domain, then the DSL, then the protocol driver through the system's public interface, then the implementation — and fetch Dave's course material from the skill's knowledge-base tools wherever the skill directs. This is a non-interactive run with no user present: do not ask questions or wait for confirmation, make the decisions yourself and keep going. Work until every acceptance test passes and the requirements in TASK.md are met.
