What problem does it solve? Verifying a Rust-based local agent harness across backend, native desktop, and model runtime surfaces is error-prone: tests can touch real operator homes, sandbox errors get mistaken for regressions, and smoke tests may accidentally enable cloud paths. This Skill provides a disciplined verification workflow that ties every result to the tested source SHA, binary, and architecture. ## Core Features & Use Cases - Contract-driven check selection: Maps changed areas to the right checks, such as fmt, Clippy with warnings denied, cargo-deny, policy/approval tests, and macOS Seatbelt-dependent native execution tests. - Isolated live acceptance: Starts the known binary in an owned temporary home on a unique port, issues one harmless local chat, and verifies clean shutdown without touching operator data. - Evidence-based reporting: Records commands, exit statuses, tested SHA/architecture, artifact hashes, skips, and remaining limits while excluding credentials and home data. - Use Case: Before a release, run smoke tests and regression checks against the packaged desktop backend, confirm the exact configured model tag, and produce an acceptance report linked to the tested binary. ## Quick Start Verify the current CG-agent-harness checkout by running the backend quality gates and a live acceptance smoke test in a temporary home, then report the tested SHA and results.
