Project install script not working (Version 3.0 - 2026-01-20)

[carlospeix]

OS: WSL 2.0 on Ubuntu 24.04
AgentOs v 3.0 - 2026-01-20

Running ~/agent-os/scripts/project-install.sh on a empty project folder outputs this:

Gave the problem to Claude Code and came up with this error and changes:

Found the bug. (( chain_depth++ )) when chain_depth=0 evaluates to 0 (the old value), which bash's set -e treats as failure and exits. This affects all (( var++ )) patterns in the script when the variable starts at 0.

After those changes the script worked with this output

$ ~/agent-os/scripts/project-install.sh
