Send x-opencode-session header on API requests (required by OpenCode Go from 09/05) #13723
Description
Hi — we operate the OpenCode Go managed-inference API, and 1154 of your users' orgs call it through Kilo Code (UA Kilo-Code/7.5.6 ai-sdk/provider-utils/4.0.27 runtime/bun/1.3.14).
Starting 09/05, requests without an x-opencode-session header will error on our side — we need a stable per-conversation ID for routing/optimization. Kilo Code doesn't send it in any version we've seen.
Ask: include x-opencode-session: <stable-id-per-conversation> on all outbound inference HTTP requests. Any stable UUID per conversation works. Happy to confirm from our telemetry once a build ships it. Thanks!

Has this been not updated on vscode extension?
cavalia88 commentedon Sep 8, 2026
Can we please get this fixed? Need to use opencode inside kilocode for VScode
esfolk commentedon Sep 8, 2026
OpenCode Cli is also good, may not fit everyone's use case.
KiloCode was slow and chunky - OpenCode Cli works smooooothh.

@thdxr thanks for the bug report. This should be fixed in kilo >= 7.5.12
If there are any sessions with versions greater than this, we would love to know. Similarly, if anyone else watching this issue continues to have issues after updating to the latest version of kilo, please reach out.
Cheers!

Confirming this is only partially fixed: #13752 covers the session request path, but memory consolidation still sends no header.
On 7.5.16 with
opencode-go/deepseek-flash, chat works while every turn close fails with "Memory error · ... missing x-opencode-session" (400 MissingSessionID).Cause:
packages/opencode/src/kilocode/memory/ports.ts(memoryText()) callsgenerateText/streamTextdirectly withoutheaders, bypassingLLMRequestPrep.prepare.Same
opencode*header logic is needed there.intentionally-left-nil commentedon Sep 10, 2026
@oscarlocatelli thanks for the report. I have drafted up a revised fix here: #14015
However, I don't have an opencode go subscription on hand to test with. Are you able to build the local branch with the fix and confirm it solves your issue?
oscarlocatelli commentedon Sep 11, 2026
@intentionally-left-nil Thanks for the reply.
Yes, I can confirm that the error no longer appears.

@thdxr @intentionally-left-nil Please look at the issue above. kilo has not been properly modified yet and is causing conflicts with opencode.
Unable to use kilo's memory feature when selecting opencode models

fix: opencode's row says which OpenCode product each of its citations…
fix: opencode's free models are for OpenCode alone, in its maintainer…
