What problem does it solve? Running tests and builds across heterogeneous repositories often means guessing which toolchain is present, manually invoking runners, and losing track of which checks actually ran. This Skill compiles a verification contract first, then executes and reports every tier against it so no check is silently skipped or falsely reported as passed. ## Core Features & Use Cases - Contract-first verification: Compiles the tier list, risk level, and detection gaps via the DoFlow runtime before any command runs, so the expected scope is stated up front. - Toolchain auto-detection: Detects the repo's existing build and test runners from its manifests instead of requiring manual configuration. - Honest reporting: Reports every tier status (PASS, FAIL, UNRESOLVED, SUBSUMED, NOT_APPLICABLE, SKIPPED, NOT_RUN) and marks runs INCONCLUSIVE when required tiers cannot be resolved. - Use Case: After implementing a feature, invoke the skill to verify the build compiles, the test suite passes, and coverage numbers are reported, then record the handoff so the next workflow stage knows the verification result. ## Quick Start Ask the assistant to run the test suite and verify the build for the current project using the do-test skill.
