CodexMonitor Orchestration Skill
Skill by ara.so — Codex Skills collection.
CodexMonitor is a Tauri-based desktop and mobile app for orchestrating multiple Codex agents across local workspaces. It provides workspace management, thread persistence, git/GitHub integration, file browsing, prompt libraries, and a remote daemon mode for connecting iOS clients or headless setups.
What CodexMonitor Does
- Multi-workspace orchestration: Spawn one
codex app-server per workspace, resume threads, track unread/running state
- Thread management: Pin, rename, archive, copy threads; per-thread drafts; stop/interrupt in-flight turns
- Worktree agents: Clone agents for isolated work under app data directory (legacy
.codex-worktrees supported)
- Git & GitHub: Diff stats, staged/unstaged files, commit log, branch management, GitHub Issues/PRs via
gh
- Composer: Image attachments, autocomplete for skills (
$), prompts (/prompts:), reviews (/review), file paths (@)
- Remote daemon: Run Codex on another machine, connect iOS client via TCP (Tailscale support)
- Prompt library: Global/workspace prompts with create/edit/delete/move and run in threads
- File tree: Search, file-type icons, reveal in Finder/Explorer
- Terminal dock: Multiple tabs for background commands (experimental)

Workspace Management
Adding a Workspace
Workspaces persist to workspaces.json in app data directory.
Via UI: Sidebar → Add workspace → Select directory
Data structure (src-tauri/src/workspaces/mod.rs):
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct Workspace {
pub id: String,
pub name: String,
pub path: String,
pub codex_home: Option<String>,
pub is_remote: bool,
pub remote_host: Option<String>,
pub remote_token: Option<String>,
}
Programmatic Workspace Access
Frontend service (src/services/tauri.ts):
import { invoke } from '@tauri-apps/api/tauri';
const workspaces = await invoke<Workspace[]>('workspace_list');
const newWorkspace = await invoke<Workspace>('workspace_add', {
path: '/path/to/project',
name: 'My Project',
});
await invoke('workspace_update', {
id: 'workspace-id',
updates: { codex_home: '/custom/codex/home' },
});
await invoke('workspace_remove', { id: 'workspace-id' });
Backend command (src-tauri/src/lib.rs):
#[tauri::command]
async fn workspace_list(
state: tauri::State<'_, AppState>,
) -> Result<Vec<Workspace>, String> {
state.workspace_manager.lock().await.list_workspaces()
.map_err(|e| e.to_string())
}
Thread Management
Thread Reducer Architecture
Thread state is managed by a reducer with slices in src/features/threads/hooks/threadReducer/.
Thread reducer pattern (src/features/threads/hooks/threadReducer/index.ts):
export type ThreadAction =
| { type: 'SET_MESSAGES'; messages: Message[] }
| { type: 'ADD_MESSAGE'; message: Message }
| { type: 'UPDATE_MESSAGE'; messageId: string; updates: Partial<Message> }
| { type: 'SET_RUNNING'; running: boolean }
| { type: 'SET_UNREAD'; unread: number }
| { type: 'RESET' };
export function threadReducer(state: ThreadState, action: ThreadAction): ThreadState {
switch (action.type) {
case 'SET_MESSAGES':
return { ...state, messages: action.messages };
case 'ADD_MESSAGE':
return { ...state, messages: [...state.messages, action.message] };
case 'UPDATE_MESSAGE':
return {
...state,
: state..(
m. === action. ? { ...m, ...action. } : m
),
};
:
{ ...state, : action. };
:
initialThreadState;
:
state;
}
}
Resuming a Thread
Frontend (src/features/threads/hooks/useThreadResume.ts):
import { invoke } from '@tauri-apps/api/tauri';
async function resumeThread(workspaceId: string, threadId: string) {
const result = await invoke<{ messages: Message[] }>('thread_resume', {
workspaceId,
threadId,
});
dispatch({ type: 'SET_MESSAGES', messages: result.messages });
dispatch({ type: 'SET_UNREAD', unread: 0 });
}
Backend (src-tauri/src/codex/mod.rs):
#[tauri::command]
async fn thread_resume(
workspace_id: String,
thread_id: String,
state: tauri::State<'_, AppState>,
) -> Result<serde_json::Value, String> {
let manager = state.workspace_manager.lock().await;
let workspace = manager.get_workspace(&workspace_id)
.ok_or("Workspace not found")?;
let server = state.codex_servers.lock().await
.get(&workspace_id)
.ok_or("Server not running")?;
server.call("thread/resume", json!({ "thread_id": thread_id })).await
.map_err(|e| e.to_string())
}
Sending a Message
async function sendMessage(
workspaceId: string,
threadId: string,
content: string,
attachments?: { path: string; mime_type: string }[]
) {
await invoke('thread_send_message', {
workspaceId,
threadId,
message: {
role: 'user',
content,
attachments,
},
});
}
Thread Lifecycle Commands
await invoke('thread_interrupt', { workspaceId, threadId });
await invoke('thread_pin', { workspaceId, threadId, pinned: true });
await invoke('thread_rename', { workspaceId, threadId, name: 'New Name' });
await invoke('thread_archive', { workspaceId, threadId });
await invoke('thread_copy', { workspaceId, threadId });
Worktree Agents
Worktree agents create isolated git worktrees under <app-data>/worktrees/<workspace-id>/.
Creating a Worktree
Frontend:
const worktree = await invoke<{ path: string; branch: string }>('worktree_create', {
workspaceId: 'workspace-id',
branch: 'feature-branch',
});
console.log(`Worktree created at ${worktree.path}`);
Backend (src-tauri/src/shared/workspaces_core/worktree.rs):
pub async fn create_worktree(
workspace_path: &str,
workspace_id: &str,
branch: &str,
app_data_dir: &Path,
) -> Result<Worktree, WorktreeError> {
let worktree_dir = app_data_dir.join("worktrees").join(workspace_id);
std::fs::create_dir_all(&worktree_dir)?;
let worktree_path = worktree_dir.join(branch);
let output = Command::new("git")
.args(&["worktree", "add", worktree_path.to_str().unwrap(), branch])
.current_dir(workspace_path)
.output()?;
if !output.status.success() {
return Err(WorktreeError::GitError(
String::from_utf8_lossy(&output.stderr).to_string()
));
}
Ok(Worktree {
path: worktree_path.to_string_lossy().to_string(),
branch: branch.to_string(),
})
}
Listing Worktrees
const worktrees = await invoke<Worktree[]>('worktree_list', {
workspaceId: 'workspace-id',
});
Removing a Worktree
await invoke('worktree_remove', {
workspaceId: 'workspace-id',
path: '/path/to/worktree',
});
Git Integration
Git Diff Stats
Frontend:
const stats = await invoke<{
staged: { path: string; status: string }[];
unstaged: { path: string; status: string }[];
}>('git_diff_stats', { workspaceId: 'workspace-id' });
Backend (src-tauri/src/shared/git_ui_core/diff.rs):
pub fn get_diff_stats(repo_path: &str) -> Result<DiffStats, GitError> {
let repo = Repository::open(repo_path)?;
let mut index = repo.index()?;
let head_tree = repo.head()?.peel_to_tree()?;
let diff_index_tree = repo.diff_tree_to_index(Some(&head_tree), Some(&index), None)?;
let diff_index_workdir = repo.diff_index_to_workdir(Some(&index), None)?;
let staged = collect_diff_entries(&diff_index_tree)?;
let unstaged = collect_diff_entries(&diff_index_workdir)?;
Ok(DiffStats { staged, unstaged })
}
Branch Management
const branches = await invoke<{ name: string; current: boolean; ahead: number; behind: number }[]>(
'git_list_branches',
{ workspaceId: 'workspace-id' }
);
await invoke('git_checkout_branch', {
workspaceId: 'workspace-id',
branch: 'main',
});
await invoke('git_create_branch', {
workspaceId: 'workspace-id',
branch: 'feature-new',
fromBranch: 'main',
});
GitHub Integration
Requires gh CLI:
const issues = await invoke<GitHubIssue[]>('github_list_issues', {
workspaceId: 'workspace-id',
});
const prs = await invoke<GitHubPR[]>('github_list_prs', {
workspaceId: 'workspace-id',
});
const diff = await invoke<string>('github_pr_diff', {
workspaceId: 'workspace-id',
prNumber: 42,
});
await invoke('github_ask_pr', {
workspaceId: 'workspace-id',
prNumber: 42,
question: 'What does this PR change?',
});
Backend (src-tauri/src/shared/git_ui_core/github.rs):
pub async fn list_prs(repo_path: &str) -> Result<Vec<GitHubPR>, GitHubError> {
let output = Command::new("gh")
.args(&["pr", "list", "--json", "number,title,author,state"])
.current_dir(repo_path)
.output()
.await?;
if !output.status.success() {
return Err(GitHubError::CliError(
String::from_utf8_lossy(&output.stderr).to_string()
));
}
Ok(serde_json::from_slice(&output.stdout)?)
}
Remote Daemon Mode
Remote daemon mode allows running Codex on a separate machine (e.g., desktop) and connecting from iOS or other clients.
Desktop Daemon Setup
Via UI:
- Settings → Server
- Set
Remote backend token (shared secret)
- Click
Start daemon in Mobile access daemon
Standalone Daemon CLI:
cd src-tauri
cargo build --bin codex_monitor_daemon --bin codex_monitor_daemonctl
./target/debug/codex_monitor_daemonctl start
./target/debug/codex_monitor_daemonctl status
./target/debug/codex_monitor_daemonctl stop
./target/debug/codex_monitor_daemonctl start \
--listen 0.0.0.0:4732 \
--token $REMOTE_TOKEN \
--data-dir /path/to/app/data
Daemon RPC Architecture
Daemon entrypoint (src-tauri/src/bin/codex_monitor_daemon.rs):
#[tokio::main]
async fn main() -> Result<()> {
let listener = TcpListener::bind(&args.listen).await?;
let shared_state = Arc::new(DaemonState::new(app_data_dir, codex_path)?);
loop {
let (socket, _) = listener.accept().await?;
let state = shared_state.clone();
tokio::spawn(handle_connection(socket, state));
}
}
async fn handle_connection(socket: TcpStream, state: Arc<DaemonState>) {
let (reader, writer) = socket.into_split();
let reader = BufReader::new(reader);
let mut writer = BufWriter::new(writer);
let mut lines = reader.lines();
while let Some(line) = lines.next_line().await? {
let request: JsonRpcRequest = serde_json::from_str(&line)?;
= (request, &state).;
writer.(serde_json::(&response)?.()).?;
writer.().?;
writer.().?;
}
}
RPC routing (src-tauri/src/bin/codex_monitor_daemon/rpc.rs):
pub async fn handle_rpc_request(
request: JsonRpcRequest,
state: &DaemonState,
) -> JsonRpcResponse {
match request.method.as_str() {
"workspace/list" => workspace_list(state).await,
"workspace/add" => workspace_add(request.params, state).await,
"thread/list" => thread_list(request.params, state).await,
"thread/resume" => thread_resume(request.params, state).await,
"thread/send" => thread_send(request.params, state).await,
"git/diff_stats" => git_diff_stats(request.params, state).await,
_ => JsonRpcResponse::error(-32601, "Method not found"),
}
}
iOS Client Connection (Tailscale)
Desktop (Tailscale helper):
- Settings → Server → Tailscale helper
- Click
Detect Tailscale → note suggested host (e.g., your-mac.your-tailnet.ts.net:4732)
iOS:
- Settings → Server
- Enter desktop Tailscale host and matching token
- Tap
Connect & test
Frontend client (src/services/remoteDaemon.ts):
class RemoteDaemonClient {
private socket: WebSocket | null = null;
private requestId = 0;
async connect(host: string, token: string): Promise<void> {
this.socket = new WebSocket(`ws://${host}`);
await new Promise((resolve, reject) => {
this.socket!.onopen = () => {
this.send('auth', { token }).then(resolve).catch(reject);
};
this.socket!.onerror = reject;
});
}
async send(method: string, params: any): Promise<any> {
const id = ++this.requestId;
const request = { : , id, method, params };
( {
= () => {
response = .(event.);
(response. === id) {
.!.(, handler);
(response.) {
( (response..));
} {
(response.);
}
}
};
.!.(, handler);
.!.(.(request));
});
}
}
Composer & Autocomplete
Autocomplete Triggers
$ — skills
/prompts: — prompts
/review — code review
@ — file paths
Frontend autocomplete hook (src/features/composer/hooks/useAutocomplete.ts):
export function useAutocomplete(value: string, cursorPosition: number) {
const [suggestions, setSuggestions] = useState<Suggestion[]>([]);
useEffect(() => {
const prefix = value.slice(0, cursorPosition);
if (prefix.endsWith('$')) {
invoke<string[]>('autocomplete_skills', { prefix }).then(setSuggestions);
} else if (prefix.includes('/prompts:')) {
invoke<Prompt[]>('autocomplete_prompts', { prefix }).then(setSuggestions);
} else if (prefix.endsWith('@')) {
invoke<string[]>('autocomplete_files', {
workspaceId,
prefix,
}).then(setSuggestions);
} else {
setSuggestions([]);
}
}, [value, cursorPosition]);
return suggestions;
}
Follow-up Behavior
Settings → Composer → Follow-up default:
Queue — queue messages if agent is running
Steer — interrupt current turn and steer
Override for single message:
- macOS:
Shift+Cmd+Enter
- Windows/Linux:
Shift+Ctrl+Enter
Prompt Library
Prompts load from $CODEX_HOME/prompts (or ~/.codex/prompts).
Prompt File Format
---
description: Generate unit tests for a function
args:
- name: function_name
description: Name of the function to test
---
Generate comprehensive unit tests for the function `{{function_name}}`, covering edge cases and error handling.
Managing Prompts
const prompts = await invoke<Prompt[]>('prompt_list', { workspaceId });
await invoke('prompt_create', {
workspaceId,
name: 'generate-tests',
content: '...',
isGlobal: false,
});
await invoke('prompt_run', {
workspaceId,
threadId,
promptId: 'generate-tests',
args: { function_name: 'calculateTotal' },
});
await invoke('prompt_run_new_thread', {
workspaceId,
promptId: 'generate-tests',
args: { function_name: 'calculateTotal' },
});

[features]
collaboration_modes = true
unified_exec = true
apps = false
[personality]
tone = "professional"
Load/save via:
const config = await invoke<CodexConfig>('get_codex_config_path');
await invoke('codex_doctor');
iOS Development
Build for Simulator
./scripts/build_run_ios.sh
Build for USB Device
./scripts/build_run_ios_device.sh --list-devices
./scripts/build_run_ios_device.sh --device "<device name>" --team <TEAM_ID>
Signing Configuration
Preferred: src-tauri/tauri.ios.local.conf.json (gitignored):
{
"bundle": {
"iOS": {
"developmentTeam": "YOUR_TEAM_ID"
}
},
"identifier": "com.yourcompany.codexmonitor"
}
TestFlight Release
./scripts/release_testflight_ios.sh
Required env vars in .testflight.local.env:
IOS_TEAM_ID=YOUR_TEAM_ID
BUNDLE_ID=com.yourcompany.codexmonitor
TESTFLIGHT_BETA_GROUP="Beta Testers"
APPLE_ID=your-apple-id@example.com
APP_STORE_CONNECT_TEAM_ID=YOUR_ASC_TEAM_ID
Terminal Dock
Experimental feature for background commands.
await invoke('terminal_exec', {
workspaceId,
tabId: 'tab-1',
command: 'npm test',
});
await invoke('terminal_create_tab', { workspaceId, name: 'Tests' });
await invoke('terminal_close_tab', { workspaceId, tabId: 'tab-1' });
Troubleshooting
Native Build Errors
npm run doctor
Common issues:
- CMake not found: Install CMake
- bindgen errors (Windows): Install LLVM/Clang
- Rust targets missing (iOS):
rustup target add aarch64-apple-ios aarch64-apple-ios-sim
Codex Not Found
Set custom Codex path in Settings → General → Codex binary path, or ensure codex is in PATH.
Remote Daemon Connection Fails
- Confirm daemon is running:
./target/debug/codex_monitor_daemonctl status
- Check token matches between desktop and client
- Verify host/port reachable (Tailscale: both devices online in same tailnet)
- Check firewall rules for listening port (default 4732)
Thread Resume Shows Stale Messages
Threads are restored from disk via thread/resume. If messages are stale:
- Ensure workspace
cwd matches thread working directory
- Restart workspace server: Remove and re-add workspace
Worktree Creation Fails
Ensure workspace is a git repository:
cd /path/to/workspace
git status
Legacy worktrees under .codex-worktrees/ are supported but new ones use <app-data>/worktrees/<workspace-id>/.
iOS Signing Issues
First-time device setup:
- iPhone unlocked and trusted with Mac
- Developer Mode enabled on iPhone (Settings → Privacy & Security → Developer Mode)
- Open Xcode via
./scripts/build_run_ios_device.sh --open-xcode and approve signing
