Eliminates flaky tests by replacing arbitrary timeouts with smart condition polling for actual state changes.
Condition-Based Waiting is a specialized Claude Code skill designed to resolve race conditions and timing dependencies in test suites. It provides patterns and implementation logic to replace fragile sleep and timeout calls with dynamic polling mechanisms that wait for specific events, state changes, or file existence. By ensuring tests wait for actual conditions rather than arbitrary time intervals, this skill significantly improves test reliability, reduces execution time in CI/CD pipelines, and eliminates inconsistent pass/fail behavior across different environments.
