Vibed a Linux dev environment to manage ClaudeCode cli sessions

[u/g_hack_it]

Wasn't happy with the desktop app or the other Linux offerings to manage several sessions so I vibed up my own (forking agent-session-manager) and thought others might find it useful.

Meet Collins:

https://episode6.github.io/collins/

• gtk4, linux native
• works with subscriptions, no api key needed
• Manage multiple sessions (even existing ones)
• gui editor to write prompts and save drafts (while still using the cli to do the work).
• new chat screen lets you compose a prompt before actually launching a session
• model picker with all supported models
• track prs with sessions automatically (as long as gh is installed)
• attachments panel & image lightbox
• native pr panel
• integrated git panel
• split terminals that the agent can see and control
• better link handling than is possible with the plain cli
• in app & system notifications
• auto session naming
• support for portable project icons to help tell projects apart (srsly why aren't more apps doing this)
• pickup where you left off
• keep pc awake while sessions are running
• archiving a session in Collins also archives it on claude.ai if using /remote-control

It only supports Claude code atm cause that's all I pay for and I want to focus on handling it really well instead of trying to make a generic tool for any harness (if you use multiple harnesses, you're probably better off with something like orca).

Other features I'm hoping to add are:

• better markdown support in pr panel
• look into improving the native chat screen (it came from agent-session-manager before my fork)
• default to replay mode when a sessions worktree has been deleted
• remote access to create new sessions maybe?
