Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Control and inspect the built-in Web UI (packages/serve) — start, stop, status, openKey capabilities
- →Show Web UI server status
- →Start the Web UI server in the background
- →Stop the running Web UI server
- →Open the Web UI in the default browser
- →Detect port conflicts before starting the server
How it works
This skill controls the built-in Web UI server by checking its status, managing its lifecycle (start/stop), and opening it in a browser. It also detects if the required port is already in use.
Inputs & outputs
When to use omcustomcodex:web
- →Check if the web UI is running
- →Stop the background server
- →Open the web UI dashboard
About this skill
Web UI Control
Interactive control for the built-in Web UI server (packages/serve).
Arguments
| Argument | Action |
|---|---|
status (default) | Show server status (PID, port, URL) |
start | Start the Web UI server in background |
stop | Stop the running Web UI server |
open | Open the Web UI in the default browser |
Workflow
Step 1: Check Server Status
Run these checks via Bash:
PORT=${OMCODEX_PORT:-${OMCUSTOM_PORT:-4321}}
PID_FILE="$HOME/.omcodex-serve.pid"
PID=$(cat "$PID_FILE" 2>/dev/null)
# Process alive?
if [ -n "$PID" ] && kill -0 "$PID" 2>/dev/null; then
STATUS="running"
else
STATUS="stopped"
# Clean stale PID file
[ -f "$PID_FILE" ] && rm "$PID_FILE"
fi
# Port check
PORT_PID=$(lsof -ti :$PORT 2>/dev/null | head -1)
echo "STATUS=$STATUS PID=$PID PORT=$PORT PORT_PID=$PORT_PID"
Step 2: Display Status
Web UI Control
─────────────
Status: ● Running (PID {PID})
URL: http://localhost:{PORT}
PID: ~/.omcodex-serve.pid
or
Web UI Control
─────────────
Status: ○ Stopped
Port: {PORT} (free)
Step 3: Execute Subcommand
| Subcommand | Action |
|---|---|
status | Display status from Step 2, then exit |
start | If stopped → run omcodex serve via Bash. If running → show URL |
stop | If running → run omcodex serve-stop via Bash. If stopped → inform user |
open | If running → open http://localhost:{PORT} (macOS). If stopped → ask to start first |
Step 4: Port Conflict Detection
Before start, check if port is already occupied by another process:
PORT_PID=$(lsof -ti :$PORT 2>/dev/null | head -1)
if [ -n "$PORT_PID" ]; then
PROC=$(ps -p $PORT_PID -o comm= 2>/dev/null)
echo "Port $PORT is occupied by $PROC (PID $PORT_PID)"
fi
If occupied by a non-serve process, warn the user and suggest --port option.
No Argument Behavior
When called without arguments (/omcustomcodex:web):
- Show status
- If stopped, suggest: "Run
/omcustomcodex:web startto start the server" - If running, suggest: "Run
/omcustomcodex:web opento open in browser"
When not to use it
- →The task requires interaction with a different web server
Limitations
- →The skill controls only the built-in Web UI (packages/serve)
- →Opening the Web UI is specific to macOS for the 'open' command
How it compares
This skill provides direct command-line control over the Web UI server, offering specific actions like status checks and port conflict detection, unlike manually managing server processes.
