@ -163,6 +163,17 @@ The log captures the request (model id, body byte length), each HTTP attempt (st
wait, elapsed ms), every stream event payload, and the terminal finish reason + usage. It is
useful for diagnosing model selection, retry, tool-call, and finish-reason issues.
## ZDR header toggle
The `x-cmd-zdr: 1` request header is **omitted by default** because it is rejected by some
models. Set `COMMANDCODE_ZDR=1` (or `true`/`yes`) when launching opencode to opt back in. The
value is read once at provider load, so restart opencode after changing it. Per-provider
overrides still win: `headers: { "x-cmd-zdr": "..." }` in `opencode.json` takes precedence over
the environment variable.
With `COMMANDCODE_DEBUG` enabled, the trace logs a `zdr on|off` line per request so the toggle
state is observable.
