The selected model is validated through getModel(taskModel.providerID, taskModel.modelID, input.sessionID).agentName or agents.defaultInfo().

It then calls prompt with sessionID, optional messageID, resolved model, resolved agent, parts, and variant, and publishes Command.Event.Executed with command name, sessionID, arguments, and the resulting message ID.SessionPrompt.PromptInput contains required sessionID and parts, with optional messageID, model, agent, noReply, tools, format, system, and variant. parts accepts SessionV1.TextPartInput, FilePartInput, AgentPartInput, or SubtaskPartInput; tools is deprecated because tools and permissions were merged.SessionPrompt.LoopInput contains only sessionID. ShellInput contains sessionID, optional messageID, required agent, optional model, and required command.SessionPrompt.CommandInput contains optional messageID, required sessionID, optional agent, optional string model, required arguments, required command, optional variant, and optional file-only parts whose fields are optional id, literal type: "file", required mime, optional filename, required url, and optional source.createStructuredOutputTool() in /home/byk/Code/opencode/packages/opencode/src/session/prompt.ts removes $schema from the provided schema, creates an AI SDK tool using jsonSchema(toolSchema), calls input.onSuccess(args) after SDK validation, and returns { output: "Structured output captured successfully.", title: "Structured Output", metadata: { valid: true } }; toModelOutput maps that to { type: "text", value: output.output }.bashRegex = /!\([^`]+)`/g, argsRegex = /(?:[Image\s+\d+]|"[^"]"|'[^']'|[^\s"']+)/gi, placeholderRegex = /$(\d+)/g, and quoteTrimRegex = /^["']|["']$/g`.SessionPrompt.node depends on, in exact order: 1.

Intended instance-free examples are models, serve, web, account, db, and upgrade; a function form supports cases such as run --attach <url>.effectCmd dynamically imports InstanceStore and InstanceRef, loads context through store.load({ directory }), provides InstanceRef to the handler, and guarantees store.dispose(ctx) in a JavaScript finally block after success or failure.effectCmd dynamically imports AppRuntime, casts yargs’ rawArgs to WithDoubleDash<Args> at the boundary, and propagates errors to the existing top-level handler in src/index.ts; CliError is recognized by FormatError in src/cli/error.ts.
