Open dev server

Find dev servers running in tmux panes and open in browser.

Usage

/open - list servers, open if only one found /open /api/docs - open with path appended /open my app - match server by freetext (match against pane name or command)

Steps

1. Run the discovery script:

./find-servers.sh

2. Parse the tab-separated output: PANE\tPORT\tCOMMAND

3. Decide what to open:

   • If ARGUMENTS starts with /, it's a literal path - append to the chosen server
   • Otherwise, ARGUMENTS is freetext - use it to match against pane names and commands to pick the right server
   • If no arguments given, use conversation context to infer which server and path to open
   • If one server found, use it
   • If multiple servers found and context doesn't clarify, show a table and ask the user to pick
   • If no servers found, tell the user

4. Open in browser:

open "http://localhost:$PORT$PATH"

Arguments: $ARGUMENTS
