A deterministic validation harness for AI agent skill execution. Each SDD workflow step is an isolated skill module invoked by natural language, ie "I want to write the spec to add..".
A single binary spec-bridge-skill-tool , acts as a schema-validating, outcome-verifying harness that AI agents call at the end of each skill's instruction set.
