Select an existing project or open a local directory. Git projects also show a workspace selector: * **Local repository** runs in your current checkout. * **Existing workspace** targets an already-created worktree. * **Create new worktree** prepares an isolated branch before the prompt is sent. ## Select an agent and model The agent controls instructions, tools, permissions, and working style. The model picker shows models from connected providers. Variants such as reasoning effort appear when the provider supports them. ## Submit the first prompt The initial prompt creates a durable session and promotes the draft tab. You can attach images and supported files before submission. A session remains associated with its project and workspace. ## Work with tool calls The timeline streams assistant output, tool input, results, reasoning, and errors. TurenOS pauses for permission when a tool requests authority that has not already been allowed or denied. Use the review panel to inspect changed files and line comments. Use the terminal or Git surfaces for independent verification. ## Continue or redirect * A normal follow-up **steers** the active session at the next safe provider-turn boundary. * A queued follow-up is promoted one at a time after in-flight tool calls settle. * Stop interrupts the active execution chain without deleting durable history. * Revert returns the workspace and conversation to an earlier user message when supported. Ask for evidence: file paths, line numbers, commands, test output, hashes, or captured security flows. A verified result is more useful than a confident summary.
