263263Enterprise administrators can use `allowManagedHooksOnly` to restrict which hooks run:
264264
265265* Your user, project, local, and plugin hooks are blocked. Hooks from plugins force-enabled in managed settings `enabledPlugins` are exempt
266* Claude Code also narrows your [`statusLine`](/docs/en/statusline), [`fileSuggestion`](/docs/en/settings#file-suggestion-settings), and [`subagentStatusLine`](/docs/en/statusline#subagent-status-lines) settings to managed settings
267* Claude Code also disables plugins with a [`command` source](/docs/en/plugin-marketplaces#command-sources), including plugins force-enabled in managed settings `enabledPlugins`, unless [`disableCommandPluginSources`](/docs/en/settings#available-settings) is explicitly set to `false`

271271Hook entries merge across settings levels rather than replacing each other: user, project, and local settings add their own hooks without removing managed ones, and the [`disableAllHooks`](#disable-or-remove-hooks) setting can't disable managed hooks from outside managed settings.

275275* `allowedHttpHookUrls`: when defined at any settings level, Claude Code runs an HTTP hook handler only if its URL matches the merged allowlist
276276* `httpHookAllowedEnvVars`: when defined, Claude Code interpolates only the environment variables on that list into hook headers

1782There is no timeout or retry limit. The session remains on disk until you resume it, subject to the [`cleanupPeriodDays`](/docs/en/settings#available-settings) retention sweep, which deletes session files after 30 days by default, following the [retention sweep rules](/docs/en/claude-directory#cleaned-up-automatically). If the answer is not ready when you resume, the hook can return `"defer"` again and the process exits the same way. The calling process controls when to break the loop by eventually returning `"allow"` or `"deny"` from the hook.

17841784`"defer"` only works when Claude makes a single tool call in the turn. If Claude makes several tool calls at once, `"defer"` is ignored with a warning and the tool proceeds through the normal permission flow. The constraint exists because resume can only re-run one tool: there is no way to defer one call from a batch without leaving the others unresolved.

2663`policy_settings` changes can't be blocked. Hooks still fire for `policy_settings` sources, so you can use them for audit logging, but any blocking decision is ignored. This ensures enterprise-managed settings always take effect.
2663`policy_settings` changes can't be blocked. Hooks still fire for `policy_settings` sources when a managed settings file on the machine changes, so you can use them to log those edits, but any blocking decision is ignored. This ensures enterprise-managed settings always take effect. Claude Code doesn't run `ConfigChange` hooks when [server-managed settings](/docs/en/server-managed-settings) arrive or refresh.
26642664
26652665Claude Code acts on the blocking decision from a ConfigChange hook's JSON output and discards `systemMessage` and `continue`. A blocked change surfaces no message to you or to Claude, whether you block with `reason` or with stderr on exit 2. Claude Code only writes a line to the debug log.

31513151
3152In addition to command, HTTP, and MCP tool hooks, Claude Code supports prompt-based hooks (`type: "prompt"`) that use an LLM to evaluate whether to allow or block an action, and agent hooks (`type: "agent"`) that spawn an agentic verifier with tool access. Not all events support every hook type.
