[ACP] Opencode sets rawInput back to empty #7370
Description
Description
Here is an example tool call when using opencode acp (removed irrelevant fields):
[
{
"update": {
"kind": "execute",
"rawInput": {},
"sessionUpdate": "tool_call",
"status": "pending",
"title": "bash",
"toolCallId": "id1"
}
},
{
"update": {
"rawInput": {
"command": "echo 'foo'",
"description": "Print 'foo'"
},
"sessionUpdate": "tool_call_update",
"status": "in_progress",
"toolCallId": "id1"
}
},
{
"toolCall": {
"kind": "execute",
"rawInput": {},
"status": "pending",
"title": "bash",
"toolCallId": "id1"
}
},
{
"update": {
"rawInput": {
"command": "echo 'foo'",
"description": "Print 'foo'"
},
"sessionUpdate": "tool_call_update",
"status": "in_progress",
"toolCallId": "id1"
}
}
]As you can see, we:
- Get the initial SessionUpdate for the tool call
- Get an update with command and description
- Get a permission request that sets
rawInputback to{} - Get an update for the status that sets
rawInputback to the state from before the permission request.
This is unfortunate, because that means when we display the details of the tool call to the user, they have nothing to base their decision on except the title and kind, which didn't get overwritten.

Ref: above issue, based on my reading of the spec I think there is no reason to send all that information on each update.

/oc I think? this may have been a recent regression, investigate the acp implementation and make a fix if u can figure out the issue

Is how this should be handled explicetely defined in the ACP protocol? The convention seems to be that OpenCode should send
title = "full bash command here"like others are doing. See here for more details: carlos-algms/agentic.nvim#232 (comment)leduckhc commentedon May 19, 2026
Why I can see several implementations here and PRs, such as #7374, but are all closed? This bug/inconsistency is really annoying. Is there somebody willing to merge the fix?
