What problem does it solve? Running tests is easy, but diagnosing why they fail and deciding who should fix them is not. This Skill provides a stack-agnostic, read-only test orchestration core that runs project test commands, classifies every failure by root cause, and routes the fix to the right executor instead of patching code blindly. ## Core Features & Use Cases - Fixed diagnostic pipeline: pre-check for orphaned runs, sequential blocking execution, diagnosis, routing, and a maximum of one fix-retest iteration before escalation. - Root cause classification: every failure is categorized as code defect, test defect, environment/infrastructure issue, flaky test, or unclassifiable, with escalation instead of guessing. - Structured reporting: produces PASSED or FAILED reports with per-test failure tables, root cause localization, and recommended executors. - Use Case: A project wrapper skill imports this core and defines stack-specific test commands and a root-cause-to-executor routing table; the core then enforces the read-only contract and diagnostic discipline across unit, integration, smoke, and e2e levels. ## Quick Start Import this core from a project wrapper skill and ask the agent to run the full test suite and report any failures with root cause analysis.
