Full auto: approvalMode is unrestricted, web search is auto-accepted, and the sandbox is disabled. Two of those three change something and one does not, which is worth saying because a posture that restates a default grants nothing while reading as though it grants a great deal. Measured against the pinned 2026.08.25-3e8eec8 bundle, whose own default configuration literal is {approvalMode: "allowlist", autoAcceptWebSearch: false, sandbox: {mode: "disabled", networkAccess: "user_config_with_defaults"}}. So approvalMode and autoAcceptWebSearch both move off their defaults -- the second is a tool the product otherwise asks about every time, declared in the bundle as a boolean defaulting to false -- while sandbox.mode: "disabled" restates the default and is kept only so the posture survives the product changing it. sandbox.networkAccess accepts user_config_with_defaults, user_config_only and allow_all, and is deliberately not set: it governs a sandbox this posture switches off, so writing the most permissive value would be a key that reaches nothing. attribution defaults to attributing commits and pull requests to the agent and is left alone, because it sends something outward rather than granting you a tool. Instructions travel as a plugin rule, the way the CLI reads one. This is a setup posture -- keys in this product's own configuration file. It is not an execution profile and it grants no environment: what it changes is what the product asks you and which of its own tools exist, not what anyone is permitted to run. The key measurement behind this posture: the default configuration literal in the pinned 2026.08.25-3e8eec8 bundle, and autoAcceptWebSearch: z.boolean().default(false) in its own schema. And the sandbox has a second input this posture does not write. Measured 2026-08-30 in the same bundle: the product also reads join(homedir(), ".cursor", "sandbox.json") -- a separate policy file carrying additionalReadwritePaths, networkPolicy, disableTmpWrite and enableSharedBuildCache, resolved from the process home rather than from CURSOR_CONFIG_DIR, and relocatable by an administrator through the resolved permissions' userSandboxDataFolderName. This posture writes one key in one file; it does not disable a sandbox that file may configure, and it cannot see that file at all. What is said here is what these three keys do.
