OpenCode CLI

See the generated compatibility matrix for capability details and version-scoped evidence.

opencode-cli is the OpenCode-backed harness for teams that already rely on OpenCode as their command-line assistant layer.

Good fit

Provider-flexible environments that already use OpenCode
Workflows where you want ctrlyoke orchestration without switching assistant tooling

Install with npm install -g opencode-ai and make sure opencode models lists the models you want before selecting this harness.
The workflow surface is the same as the other CLI harnesses.
Models use OpenCode's provider/model form. The dashboard lists what opencode models reports for your setup.
Tool permissions (mode, allowedTools, deniedTools), MCP servers, and ctrlyoke's completion plugin are delivered per process through OPENCODE_CONFIG_CONTENT; ctrlyoke does not write a workspace opencode.json. OpenCode's own categories are coarser than tool patterns (for example, write and edit both map to OpenCode's edit permission).
permissions.trustedExternalRoots is not passed to OpenCode; it has no --add-dir equivalent.
