How to display the file name details for “read” tool?

[haimanman]

I’m using the OpenCode agent as the backend. Why don’t tool calls like read/patch show file name information, and how should I configure this?

@0xmrpeter I noticed that in the screenshot you shared, the file name is shown after “read.”

Hey! Thanks for bringing this up — it's a real gap and your report helped us identify the root cause.

Why it happens: OpenACP displays file names by reading the file_path field from the tool's input metadata. However, OpenCode sends this field as filePath (camelCase) instead of file_path (snake_case), so the parser doesn't pick it up and falls back to showing just the tool name (e.g. "Read" with no file).

The same issue affects apply_patch and a few other tools that don't send a standard kind, so they show up with minimal context in the tool card.

What's being done: PR #203 by @hightman addresses exactly this — adding camelCase field support and improving titles for tools like apply_patch and todowrite. We're doing a quick review pass on the architecture before merging to make sure it lands cleanly across all adapters, not just Telegram.

In the meantime: There's no config option to work around this right now, but the fix should be in the next release once the PR is merged. If you're running OpenACP from source you can track the PR directly.

Thanks again for the detailed report — the screenshot was super helpful!
