This issue might be a duplicate of existing issues. Please check:

• task tool "SyntaxError: Unexpected end of JSON input" #3034: Same exact error message "SyntaxError: Unexpected end of JSON input" with task tool and tool calls failing, making build mode degraded/unusable

Feel free to ignore if none of these address your specific case.

in this case what i am noticing is that the agents first step happens to be creating some folders and subfolders and it is using / instead of \

i am not sure why this is such an issue, or if something broke in the tool calling. it is still doing this even after downgrading back to .0.15.39

for example:
mkdir development/terminal-frontend
The syntax of the command is incorrect. OC just aborts and stops.

instead i can manually run; mkdir development\terminal-frontend

I am also getting this in pwsh on windows.

For whatever reason this only seems to happen on windows

I've done some digging, weirdly the first message succeeds then all subsequent calls fail:

SyntaxError: Unexpected end of JSON input

Windows 11 Terminal - installed via:
winget install OpenJS.NodeJS.LTS
npm install -g opencode-ai

Mines a bit different I feel as it's in the prompt and I get stuck
I actually have to: ctrl+p undo command to regain the prompt

On my end, it's not tool calls, but specifically the bash tool. Other tools work just fine.

Maybe something in bash.ts ...

After some quick pairing, @Hona and I fixed the issue, in #4234
