The sandbox is off by default and native Windows has none.\n\n**Harness.** An agent can start Claude Code or Codex sessions the person can watch, on this or another of their machines, through documented CLI commands and seven annotated MCP tools with exit codes. Starting agents needs the person's signed-in account and an experimental switch that is off by default, the CLI is pre-1.0, and usage counts are shared by default.\n\n## Before you call either\n\n### Claude Code\n\n1. Pass `--permission-mode`, `--max-turns` and `--max-budget-usd` on every `claude -p` run. The unset mode changed again in 2.1.302, and the docs page still gives the older rule\n2. Turn on the sandbox with `sandbox.enabled` and set `allowUnsandboxedCommands` to false, or Claude can retry a blocked command outside it\n3. Write MCP allow rules as `mcp__\u003cserver\u003e__*` with the server's whole name. Since 2.1.299 a rule for `mcp__a` no longer covers a server named `a__b`\n4. Set `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1` on a Claude login to stop metrics and error reports in one go\n5. Set `autoUpdatesChannel` to stable or `DISABLE_AUTOUPDATER=1` in CI. Native installs update themselves about once a day\n\n### Harness\n\n1. Run `harness whoami` first. If it says you may not start harnesses, tell the person and do the work yourself\n2. Ask the person before installing Harness, and leave `harness login` and the agents-start-agents switch to them\n3. Treat exit 5 as final and do not retry. Treat exit 3 as needs the person, and never answer a harness's question or permission prompt\n4. Name every harness, put the whole task in `harness new`, then wait, read with `harness show` and close only the ones you started\n5. Run each `harness` command on its own or joined with `\u0026\u0026`, since piped commands no longer match the permission rule\n\n## Questions\n\n### Which is better for AI agents, Claude Code or Harness?\n\nHarness and Claude Code score within a point of each other on agent readiness, 60.3 (C) and 59.9 (C). Claude Code leads on reliability, agent ergonomics, security \u0026 auth, maintenance \u0026 community and transparency \u0026 trust.\n\n### Are Claude Code and Harness open source?\n\nNo open-source release is listed for Claude Code.
