Permission prompts don't say what is being approved #50234

When opencode asks me to approve access to a directory outside the working
directory, the prompt tells me the directory and nothing else. I'm asked to
grant access, but I can't tell what is about to be done to that directory or
the files in it, or why. So I either approve blind or reject something that
was probably fine.

Here's what it looks like:

All it tells me is Access external directory ~/.config/opencode and the
pattern it would allow. Whatever tool call triggered this is invisible.

At a minimum, the prompt should show the exact tool call that requires the
approval — the command for a shell tool, the path and target for a file
operation, and so on. Ideally it would also show what the agent is trying to
do and why, since that context exists in the conversation right before the
prompt appears.

I hit this most with shell commands that touch paths outside the working
directory. In that case the command is already known to the permission
system, it just isn't shown to me. I'd expect to see something like:

$ rg -n "old-path" /srv/data

(or the file path for a read/write).

There's no way for me to get this from the prompt itself, and rejecting
blind on every outside-directory request isn't workable.

Happy to test a fix.
