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**OpenCode.** Runs with no key or account on free OpenCode Zen models. Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox.\n\n## Before you call either\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### OpenCode\n\n1. Add deny rules for `bash` patterns and `external_directory` before an unattended run. Most tools default to allow\n2. Set `\"autoupdate\": false` or `OPENCODE_DISABLE_AUTOUPDATE=1` and pin the version in CI\n3. Configure a provider key. With none, prompts go to free Zen models that may train on them\n4. Set `OPENCODE_SERVER_PASSWORD` before `opencode serve`. Without it the server runs unauthenticated\n5. Install `opencode-ai` for the 1.x server API and SDK. After `opencode upgrade --major`, use `@opencode/client` and add an `external_directory` ask rule\n\n## Questions\n\n### Which is better for AI agents, Harness or OpenCode?\n\nOpenCode scores 68.5 (B) on agent readiness against Harness's 60.3 (C), and leads in 5 of 7 scored categories.\n\n### Are Harness and OpenCode open source?\n\nYes. Harness is open source (MIT).
