Harness Engineering Playbook A skills.sh-compatible skill that operationalizes the practices from OpenAI's Harness Engineering guide. Use it to set up or refactor agent-first workflows so that autonomous runs are repeatable, observable, and safe. Install What It Does - Bootstraps harness artifacts: , , , , , and CI workflows. - Wraps deterministic commands behind , , so agents can run them reliably. - Enforces strict module boundaries and data-shape contracts. - Wires structured observability (correlation IDs, key transitions) from day 1. - Adds entropy-control audits and nightly harness chec…
