plannotator slash commands don't work in claude background sessions

[UberMouse]

Using claude agents if you spawn a background session agent, navigate into it, run a slash command like /plannotator:plannotator-review nothing happens and the review session does not open in a browser. If I then open the same directory directly with claude and run the same slash command it works fine.

The background session is running inside of a worktree, don't know if that matters.

Hi can you try and upgrade with 0.19.20

https://github.com/backnotprop/plannotator/releases/tag/v0.19.20

The issue was directly addressed there.

Browser No-Op Sentinel Handling
Claude Code's agent view sets BROWSER=true in the process environment, a standard convention meaning "do not open a browser." Plannotator was treating this as a valid browser command, shelling out to true http://localhost:NNNN, which exits 0 without opening anything. The server then sat in waitForDecision() indefinitely with no visible URL and no way for the user to recover.

The fix recognizes documented no-op values (true, false, none, :, 0, 1) and treats them as if the variable were unset. This lets the VS Code IPC fallback fire in remote sessions and the platform default browser open in local sessions. Real browser paths like /usr/bin/firefox or macOS app names are unaffected.
