Error message from OpenCode GO

Some of your requests to OpenCode Go are missing an x-opencode-session header. If we don't have this we cannot properly optimize our service. Starting 09/06 requests missing this header may error.

Suggested fix

Generate a stable UUID per installation and include it as x-opencode-session header in all curl requests. Example:

SESSION_ID_FILE="${HOME}/.local/share/opencode/go-usage-session-id"
if [[ -f "$SESSION_ID_FILE" ]]; then
  SESSION_ID=$(<"$SESSION_ID_FILE")
else
  SESSION_ID=$(cat /proc/sys/kernel/random/uuid)
  mkdir -p "$(dirname "$SESSION_ID_FILE")"
  printf '%s' "$SESSION_ID" > "$SESSION_ID_FILE"
fi

# Add to curl calls:
curl -H "x-opencode-session: $SESSION_ID" ...
