Feature Flags
Boolean switches (default false) that gate unreleased or experimental functionality.
Extensions & Developer Tools
| Flag | Default | Description |
|---|---|---|
isDxtEnabled |
false |
Load browser extensions in app. DXT = Desktop Extension, Anthropic's extension format for the desktop client. |
isDxtDirectoryEnabled |
false |
Enables a browsable extensions directory UI. Separate from isDxtEnabled, suggesting a phased rollout (sideloading first, then directory). |
isLocalDevMcpEnabled |
false |
Allows local development MCP servers to connect to the app. For developers building custom integrations. |
isUvSystemPythonEnabled |
false |
Use the system-installed Python for UV runtime extensions instead of a managed installation. |
Prototypes & Experiments
| Flag | Default | Description |
|---|---|---|
isSparkleHedgehogEnabled |
false |
Activates the sparkleHedgehog prototype. See codenames below. |
isMidnightOwlEnabled |
false |
Activates the midnightOwl prototype. Has a corresponding setEnabled() Swift native API method, indicating macOS system-level integration beyond the web layer. |
isPhoenixRisingAgainEnabled |
false |
Debug override for a new auto-updater system. The "Again" suffix indicates this replaces a previous updater. |
isChicagoEnabled |
false |
Forces chicago_config.enabled and teachModeEnabled to true regardless of GrowthBook remote config. Requires restart. |
Internal Codenames
Anthropic uses an adjective+animal naming convention for internal prototypes (with one geographic exception). Each codename has its own configuration keys in the app's settings store.
sparkleHedgehog
| Key | Default | Type |
|---|---|---|
sparkleHedgehogAppearance |
"default" |
string |
sparkleHedgehogScale |
1 |
number |
Has an appearance setting (implying multiple appearances) and a scale factor. The keys are consistent with a UI appearance/theme system or a visual element with configurable size and style.
plushRaccoon
| Key | Default | Type |
|---|---|---|
plushRaccoonEnabled |
— | bool |
plushRaccoonOption1 |
"off" |
string |
plushRaccoonOption2 |
"off" |
string |
plushRaccoonOption3 |
"off" |
string |
Three independently togglable sub-options, all defaulting to "off" as strings (not booleans), suggesting they may have more states than just on/off. Purpose not determined from binary analysis alone.
quietPenguin
| Key | Default | Type |
|---|---|---|
quietPenguinEnabled |
— | bool |
Single on/off toggle. Name suggests notification suppression or a do-not-disturb mode.
louderPenguin
| Key | Default | Type |
|---|---|---|
louderPenguinEnabled |
— | bool |
Counterpart to quietPenguin. Same structure. Name suggests enhanced notifications or more aggressive alerting. These two form a notification spectrum: quiet ← normal → louder.
chillingSloth
| Key | Default | Type |
|---|---|---|
chillingSlothLocation |
"default" |
string |
A location setting with a "default" value. Consistent with an idle-state behavior or ambient UI element that can appear in different positions (toolbar, menu bar, floating overlay, system tray, etc.).
midnightOwl
| Key | Type |
|---|---|
Feature flag: isMidnightOwlEnabled |
bool |
Swift API: midnightOwl.setEnabled() |
method |
Has both a feature flag and a Swift native API setEnabled() method through @ant/claude-swift, meaning it hooks into macOS at the system level. The "midnight" prefix and native integration are consistent with scheduled background tasks or time-based automation. The existence of coworkScheduledTasksEnabled and ccdScheduledTasksEnabled config keys (both false) suggests scheduled task infrastructure exists in the app.
floatingAtoll
| Key | Default | Type |
|---|---|---|
floatingAtollActive |
— | bool |
| (dimensions) | 320 × 54 px | hardcoded |
| (offset) | 12 px | hardcoded |
A floating UI element with hardcoded pixel dimensions: 320px wide, 54px tall, with a 12px offset. This is the quick-access floating bar — visible to users in Cowork sessions. The naming parallels Apple's Dynamic Island ("atoll" = ring-shaped island). At 320×54px it fits a slim toolbar or single-line input. Corresponds to the quickAccess Swift native API.
chicago
| Key | Default | Type |
|---|---|---|
chicagoEnabled |
— | bool |
chicagoAutoUnhide |
— | bool |
chicagoUserDeniedBundleIds |
— | string[] |
Feature flag: isChicagoEnabled |
false |
bool (overrides GrowthBook) |
Related: teachModeEnabled |
— | bool |
The most well-documented codename and the only one that breaks the animal naming convention. This is the interactive teach mode / guided walkthrough system (see computer-use-tools.md for the teach mode tools). chicagoUserDeniedBundleIds tracks which macOS applications the user has declined to grant Claude access to during walkthroughs.
Swift Native APIs (@ant/claude-swift)
The @ant/claude-swift module is a native addon bridging Claude's Electron UI with macOS system capabilities.
| API Namespace | Purpose |
|---|---|
quickAccess |
Floating quick-access panel. System-level window management for the always-available Claude input (floatingAtoll). |
notifications |
macOS native notification delivery via Notification Center. |
desktop |
Desktop environment integration — window positioning, display detection. |
api |
Direct API communication layer for authenticated requests to Anthropic's backend. |
midnightOwl |
Native hook for the midnightOwl prototype. Exposes setEnabled(). |
vm |
Virtual machine management — isRunning, isGuestConnected. Handles lifecycle for Cowork's Linux VMs. |
hotkey |
Global keyboard shortcut registration. Works even when the app isn't focused. |
permissionFixer |
macOS permission remediation. Guides users through granting accessibility, screen recording, or automation permissions. |
computerUse |
Computer use capability bindings — screen reading, mouse/keyboard control, GUI automation. Separate SPM product, computer_use.node, nest builds only. |
Configuration Keys
Additional configuration keys found in the app's settings store.
Security & Permissions
| Key | Default | Notes |
|---|---|---|
secureVmFeaturesEnabled |
true |
VM sandboxing — Claude's compute runs in isolation |
bypassPermissionsModeEnabled |
false |
Skip permission checks. Dev-only. |
autoPermissionsModeEnabled |
false |
Auto-grant permissions without user confirmation. Dev-only. |
allowAllBrowserActions |
false |
Unrestricted browser automation |
dispatchTrustedCodeWorkspaces |
[] |
Folders where code execution is trusted without confirmation |
localAgentModeTrustedFolders |
[] |
Folders trusted for local agent operations |
Launch & Session
| Key | Default | Notes |
|---|---|---|
launchEnabled |
true |
Whether the app is allowed to launch |
launchPreviewPersistSession |
false |
Persist preview sessions across app restarts |
Capabilities
| Key | Default | Notes |
|---|---|---|
coworkWebSearchEnabled |
true |
Web search in Cowork mode |
coworkScheduledTasksEnabled |
false |
Scheduled/recurring tasks in Cowork |
ccdScheduledTasksEnabled |
false |
Scheduled tasks in Claude Code Desktop |
keepAwakeEnabled |
false |
Prevent system sleep while Claude is working |
dockBounceEnabled |
false |
Bounce Claude's dock icon for attention |
The Clod Avatar
default.clod is a zip archive found in the app binary containing assets for an alternative AI persona:
| File | Contents |
|---|---|
personality.txt |
Persona definition ("You are Clod, a minimalist AI assistant...") |
cursor.png |
Custom mouse cursor graphic |
idling_0.png, idling_1.png, idling_2.png |
Idle animation frames |
working_0.png, working_1.png, working_2.png, working_3.png |
Working animation frames |
celebrating_0.png, celebrating_1.png |
Success animation frames |
error_0.png |
Error state |
"Clod" is a play on "Claude." The .clod format is a self-contained avatar package: personality definition plus sprite sheets for different states (idle, working, celebrating, error). The working animation has multiple frames for a looping animation during processing.
This may connect to sparkleHedgehog — the appearance and scale settings could control which .clod avatar is active and how large it renders. The .clod format being a zip archive means custom avatar packs could be created and distributed.
Apple App References
String references found in index.js suggesting planned or gated native integrations:
Calendar, Reminders, Notes, Contacts, Photos, Health, Maps, Safari, Shortcuts, Music, Freeform, Focus
No tool registration patterns (name + inputSchema) were found for any of these in the current binary. These are string references only — they may represent planned integrations, configuration labels, or permission identifiers rather than functional tool implementations.
