Set Session Context

Automatically set session name and color based on the current git branch and PR.

Steps

1. Detect branch:

   git symbolic-ref --short HEAD
   

   • If detached HEAD (command fails) → stop, do nothing
   • If main or master → stop, do nothing

2. Look up PR title:

   gh pr view --json title --jq '.title'
   

3. Determine session name:

   • If PR exists → use PR title
   • If no PR → humanize branch name: strip the conventional prefix and slash/hyphen separator, replace remaining hyphens with spaces
     • feat/add-widget → add widget
     • fix-login-bug → login bug

4. Run: /rename <session name>

5. Determine color from the branch prefix (match ^(type)[/-]):

   Prefix	Color
   feat	blue
   fix	red
   chore	green
   docs	cyan
   refactor	yellow
   test	purple
   ci	orange
   build	orange
   perf	yellow
   style	cyan
   (no match)	blue

6. Run: /color <color>

Behavior

• Execute silently: do not announce, explain, or narrate what you are doing.
• Do not ask for confirmation.
• If gh is unavailable or fails, fall back to the humanized branch name.
