skills

Design tiered software tests, validation plans, QA strategy, and regression coverage across agents, APIs, CLIs, UIs, workflows, and orchestration systems.

Evaluate systems, workflows, test suites, agents, APIs, UIs, and software artifacts for trustworthiness, coverage gaps, regressions, and failure modes.

Verify current time, date, and timezone before any temporal claim. Convert relative time to absolute timestamps. Handle cross-host timezone coordination and log timestamp parsing.

Safely guide installation, upgrade, repair, rollback, and verification workflows by verifying current state, official upstream instructions, environment risk, rollback readiness, and deterministic post-change checks before producing mutating commands.
